How do you (sort-of) build the cast of undertale using pathfinder?

I admit, i love undertale, and i love pathfinder as well. so i was wonderting how to build some of those kind of characters in pathfinder.

The main ones i would like to create are Undyne(the magical spear wielding, Heavily armoured fishlike warrior "OF JUSTICE"), Alphys(the highly intelligent, socially awkward, techno-savvy Reptilian scientist), and Muffet(the bakesale Spider queen with command over a small Arachnid force(and one big Spider muffin)).

Playable versions are preferable, but not necessarily required. you can also post your own favorite characters and how you would translate them into pathfinder.

Have Fun.


Undyne is probably the easiest. Her race is a no brainer (the Undine). For class, you need something that is A) good in heavy armor, B) a capable thrower, and C) is hard to kill. Barbarian, Armored Hulk seems the most appropriate, with a Javelin of Brilliant Energy.

Okay. Other options i would consider race-wise for Undyne include gillmen(their fishlike scales and river varients vulnerability to heat are fairly solid, and they still have good con and an unaffected strength score), and most recently added (as an option in the bestiary 5) the deep one hybrid(in the true deep one form). Details are as follows:

bestiary 5 pg 70:

+2 Constitution, +2 Wisdom, –2 Dexterity

Slow: A deep one hybrid’s base speed is 20
feet

Low-Light Vision: A deep one hybrid can see twice as far as a human in starlight, moonlight, torchlight, and similar conditions of dim light.

Natural Armor: A deep one hybrid’s thick skin and dense fatty tissues grant it a +1 natural armor bonus to AC.

Final Change (Su):A deep one hybrid ages at the same rate as a half-orc. A mere 1d12 months after a deep one hybrid reaches venerable age (at 60 years old), it dies a painful, agonizing death, only to have its body transform into that of a mature deep one. This transformation functions as the reincarnate spell, with the newly formed deep one gaining the following modifications to its physical ability
scores: +6 Strength, –2 Dexterity, and +6 Constitution.

Sea Longing (Ex): Sea Longing (Ex) Every 24 hours a deep one hybrid spends in an area more than 10 miles from the sea, it must succeed at a DC 20 Will save or take 1 point of Wisdom drain.

Take to the Water (Ex):A deep one hybrid can hold its breath 10 times longer than a human can, and gains a +2 bonus on Initiative checks and Reflex saving throws while swimming. A deep one hybrid has a swim speed of 30 feet, and gains a +8 racial bonus on all Swim checks.

Languages: Deep one hybrids begin play speaking Aklo and Common.
Hybrids with high Intelligence scores can choose from
the following languages: Abyssal, Aquan, Dwarven, Elven, Giant, Gnome, Goblin, Halfling, Orc, and Undercommon.

Bracer of Infinite Daggers that produces Javelins instead?

Multi-class into monk? It would need to be a karma monk though.

Returning spear? Reflavouring Kineticist to its blasts look like spears?

Walken voice:I Don't Know.


Muffet could be an Aranea Blight Druid, with her muffin-spider being an Improved Familiar of some sort and using Vermin Empathy on the other smaller spiders.

(And if you feel bad about having those innate Sorcerer casting levels going to waste, just have her multiclass into Theurge or something. All the Blight Druid abilities she needs are low-level ones.)


Alphys is probably the simplest to actually build - she's a Lizardfolk Expert with the Technologist feat. She's a complete noncombatant, but she has a high Intelligence, low Charisma, and lots of ranks in knowledges (particularly history, engineering, arcana, and whatever would be used for remembering useless trivia about anime) and craft (alchemy) and craft (machinery).

If you want a non-NPC-class build for her, it'd probably be some variant of Alchemist.


Asgore and Toriel are both spellcasters who focus on fire magic, but Asgore mixes it up with melee attacks while Toriel seems to be just a caster. Magus or Wizard/Eldritch Knight and Sorcerer or Kinetecist respectively. Though Asgore will need some kind of archetype that makes it viable for a Magus to use a two-handed weapon like a trident.

Race-wise, the first thing that jumps to mind from their goat-like appearances is something like a Satyr or Faun, but their behavior doesn't really match the flavor. Bestiary 5 added the Glaistig as well, but I haven't gotten a chance to look at its Pathfinder interpretation so I don't know if that will fit either. I made a homebrew Glaistig years ago with the race builder, well before B5 was announced, so I guess they could use that if you wanted.

Papyrus is turning out to be surprisingly tricky to theorize a build for. Originally I was just going to write him off as a Neutral Good Skeletal Champion with some Fighter levels tacked on. The problem is that this doesn't account for his Blue Attack in any way.

Then I thought of perhaps Barbarian - Undyne does say that Papyrus is "tough as hell". The Ground Breaker chain of Rage Powers would be easily reflavored as his various bone-based combat moves, and Overbearing Advance/Onslaught could also be reflavored as him running things over with his bones. I didn't see a Rage Power that could just plain knock enemies prone, but I might have just missed it.

Obviously you'll have to rewrite/ignore some of the rules regarding undead for this to work, since no Constitution score and immunity to morale effects (both good and bad) equals not much good to be had out of Barbarian and Rage. Also you'd have to reflavor Rage as something other than being angry and out-of-control. Perhaps being flustered or excited empowers Papyrus's combat ability.


Mettaton is some kind of sapient golem or robot with a heck of a lot of DR (or Hardness? He shrugs off your laser attacks from the yellow heart) and levels in Bard. Like Papyrus, you'll need to alter or ignore a lot of the rules about what Constructs are allowed to do and what benefits and immunities they can have for him to work as displayed in the game.

When he becomes MettatonEX, he switches from being a golem to something more like a Warforged. He retains the Bard levels or even gains more in exchange for his golem HP and DR, with lots of ranks in Perform (oratory) and Perform (dance).

MettatonNEO...:
... looks like he should be a Kinetecist or maybe 3.5 Warlock with his Mega Man-looking gun. But since we never actually get to see him attack, it's hard to say.

On the subject of Bards, that's also what I'd make Napstablook. Race is, of course, a Ghost; base race unknown (or possibly straight-up none?).

Sharding property from Weapon Master's Handbook. Putting it on a spear basically gets you Undyne.

You'd need her to have a special shark-kin subtype, though. No way her attribute modifiers include a penalty to strength. This is a woman who suplexes boulders just because she can, after all.

Maybe promethan alchemist or construct rider, due to her background in robotics. I could see her maybe using a bunch of minor construct(like camera mounted spiderbots, scouting spheres, and (when in danger) some example of combat droid. direct combat is not her forte but she does have a background in advanced science.

And if constructs are not on the table(because pathfinder society just HATES giving us constuct creation), something that maximises her capacity to NOT kill her opponents, using stun, paralysis, sleep, flash, and ocassionally more lethal bombs to support the actual fighters.


That really just leaves Flowey and Sans of the major characters.

Flowey at the end of the Neutral Route is some homebrewed monstrosity that hybridizes the Plant and Aberration types, with a veritable army of templates slapped onto it. None of its attacks fit in with any class or currently-existent monster (unless you really want to be super-liberal with Wizard), so it's something the GM cooked up from scratch or perhaps even on-the-fly.

Pacifist Route:
Asriel is whatever race Asgore and Toriel are, with a sudden influx of a ton of levels in Wizard (the one melee attack he does, with the swords, could be written off as him using Transformation). His second form is, once again, the GM flying by the seat of their pants and making things up on the fly or homebrewing up a storm of a final encounter, though the appearance suggests there might be a Half-Fiend template or something like that involved. Given the nature of the fight, stats really aren't all that important anyway.

Genocide Route:
Sans can glimpse into alternate timelines, is aware of other realities, can teleport, and has an array of abilities that rivals the entirety of the rest of the combat encounters in the game. He's dodgy as hell but goes down in one hit ... IF you can hit him. Meanwhile, he's putting you through hell, attacking you with terrain, with gravity, with GIANT FRICKIN LASER BEAMS with the Gaster Blasters, and with just about every other trick in the book.

Yeah, Sans is a Wizard.

Or, yet again, the GM pulling homebrew stuff out of their backside and playing the rules extremely fast and loose.

so alter her bonuses for strength instead of wisdom, since she was also able to believe that everything she heard about humans from Alphys(which she got from anime and comic books) was true. wisdom is linked to perception as well, and considering you can simply run away from undyne a good amount before she even twigs that you are no longer there, the moment an opening presents itself.

I like that. Undyne is physically intimidating but not the best thinking wise.


She's also easily distracted, between getting pulled away from the chase due to spotting Sans, and later her constant lack of focus during the meeting at her house and the frequent interruptions and sidetracks that happen in conversations with her whenever you call Papyrus.

Her Wisdom is in the tank, easy.

Undyne tanked her wisdom and intelligence to put her strength, dexterity, and charisma through the roof. Meanwhile Alphys is sweating profusely in the considerable effort to let Undyne play the character she wants to play and not lecture her on the importance of wisdom for a martial character.

sans meanwhile has compiled a ridiculous amount of magical power, gaining ludicrous levels of magic, but mostly stores up a wide variety of spells just for use as pranks.

Papyrus, being ever the kind soul attempts to negotiate with every enemy he encounters, non-lethally subduing as many as he can.

Metatron starts to form a chain of metatron related businesses, using his wealth to become a media icon.

Toriel tries to protect the party as best she can and foster good actions, but also starts making terrible puns.

Chara keeps trying to kill everyone he meets and ruin the game for everyone, as well as deliberately playing the chaotic evil alignment.

Asgore cannot stop coming up with terrible names for his characters, but always tries to save people or, if they cannot be spared, try's to kill them as painlessly as possible, and always mourns them.

Muffet stores money away as part of a 'good cause fund', does bake sales to raise money, charges sometimes high sums of money, and always 'targets' those that are either stingy with money or showing hate to spiders.

Frisk is kind of neutral or pasifistic, but always determined to complete the quests he can, though always getting figity when people start talking about EXP and LVL, until he is reassured that it's just experience and levels, not EXecution points and LeVel of violence.

And flowey... Well... He either is trying to manipulate people or outright kill them. Kind of like chara, but not quite as violent or sadisticly torturesome as Chara.


Admittedly they're a pretty balanced party all around, if a bit large.


I FEEL THAT THIS "BARBARIAN" CLASS YOU SPEAK OF FAILS TO CAPTURE MY TRUE POTENTIAL. WHILE IT SEEMS MOST EXCELLENT, I BELIEVE IT LACKS A CERTAIN.... COOLNESS. PERHAPS THE CLASS CALLED BLOODRAGER WOULD BE A BETTER FIT FOR ME?

Bloodrage would also fit with the supernatural nature of some of his attacks. Plus, THE DESTINED BLOODLINE WOULD BE A PERFECT FIT FOR THE GREAT PAPYRUS, SINCE HIS TRUE GREATNESS IS ULTIMATELY WHAT FUELS HIS TRUELY GREAT POWERS. that or undead, but i'm still not certain on that one, while the other is more set.


I can definitely see it. The combination of the spells, bloodline, and Rage Powers pretty much puts him together perfectly.


Here's my idea for the Undertale gang in Pathfinder.

Frisk: Young Human Rogue, NG

Flowey: Ghoran Sorcerer, NE

Toriel: Tiefling cleric of Sarenrae, NG

The Great Papyrus: Obitu (A third party race of living skeletons) Paladin of Sarenrae, LG

Sans: Obitu Oracle, NG

Undyne: Gillman fighter (Dragoon), CG

Alphys: Kobold Wizard, LG

Mettaton: Android Bard, LN

Asgore: Tiefling Magus, LG


You may be interested to know that Frisk has already been built in Pathfinder, just check out p.7 of Chronicle of the Righteous. Androgynous? Check. Flirtatious? Check. E even has the same hairstyle and facial expression.

Flowey is most definitely a sorcerer with the Impossible Bloodline.


I personally am DM a full Undertale playthrough with 3 of my friends in pathfinder. It is insanly broken and stuff as it is literally going past level 80. This is what I have for the characters:

Toriel: ??? Sorcerer 40 (Arcane Bloodline)/ Wizard 40 (Fire)
Sans: Human Skeletal Champion Sorcerer 80 (Destined)/ Monk* 40/ Wizard 40 (Divination)
Papyrus: Human Skeletal Champion Bard* 20
Undyne: Undine Urban Barbarian 20/ Unbreakable 20
Alphys: Lizardfolk Scholar 20
Mettaton: Human Ghost Bard* 20/ Performance Fighter 20/ Ranger* 20 (Favored Enemy [Human]) soulfused with Iron Golem
Asgore: ??? Polearm Fighter 40/ Paladin* 20/ Wizard 20 (Fire)
Photoshop Flowey: Yellow Musk Creeper (Advanced to CR 60) Sorcerer 40 (Verdant)
Asriel: ??? Sorcerer* 40 (Starstruck/Destined)/ Two-Handed Fighter 40/ ??? 40
Undyne the Undying: Undine Paladin* 40/ Unbreakable 40/ Monk* 30/ Cavalier 30*
☝✌❄☜☼: Alchemist 20/ Sorcerer 20/ Scholar 20/ Summoner 20 (Gaster Blaster Edilon)/ Wizard 20/ Fighter* 20/ Monk* 20/ Pathfinder Chronicler 10/ Master Spy 10/ Loremaster 10/ Shadowdancer 20

*Archetype not chosen/ Name forgotten


I actually picked out classes for the six human souls:

Patience: Rogue
Bravery: Brawler
Integrity: Ascetic Entertainer
Perseverance: Wizard
Kindness: Cleric
Justice: Gunslinger

Obviously, they would all be human. I've spent an absurd amount of time statting them out, picking feats, etc. I'll probably wind up playing as each of them, in due time, they're coming along quite nicely.


Gaster; 20th level Astomoi Sorcerer (Impossible Bloodline).

I'd say throw a few mythic levels in there, Archmage?
