Juvanile Metroid

This creature resembles a jelly fish with three nuclei pulsing in the mitts of its translucency. Its toothy maw twitches hungrily as it dashes towards you.

Icy Paralysis (ex): Whenever a Metroid takes ice damage it must roll a fortitude save (dc 10 + damage done) or become paralyzed for 1d4 rounds. While thusly frozen Its energy resistances and Damage reduction are negated.

Attach (Ex) When a Metroid hits with a touch attack, its barbed teeth latch onto the target, anchoring it in place. An attached Metroid is effectively grappling its prey. The Metroid loses its Dexterity bonus to AC and has an AC of 19, but holds on with great tenacity. A Metroid has a +8 racial bonus to maintain its grapple on a foe once it is attached. An attached Metroid can be struck with a weapon or grappled itself—if its prey manages to win a grapple check or Escape Artist check against it, the Metroid is removed.

Energy Vampipre (Ex) A Metroid drains energy at the end of its turn if it is attached to a foe, Draining 2d6 points of damage which is transferred to the Metroid in the form or healing or temporary hit points. If its victim dies from this damage she is reduced to a fine inert powder, effectively disintegrated.

Energy Transfer (ex): Instead of Draining an enemy from an attached creature a Metroid can instead transfer this energy to a creature healing it up 2d6 points of damage. This ability costs the Metroid the same amount of hit points.

Lol, I'm forwarding this to a couple of friends. Now we just need some goomba's to go with these flying mushrooms.

[Evil Midnight Lurker]

A hardcore Metroid should be immune to ice damage, but suffer the paralysis effect based on the damage it would have taken.

[clff rice]

I thought about the Immune to ice damage thing but in one of the games (fusion i think it was) there was an Omega metroid which-could be harmed by ice missiles. Maybe the younger ones are more resilient not sure It just worked thematically.

[Kelandis]

Hey, sorry if this is a bit of a necro. I really liked your concept for the metroid and decided to refine it a bit.
Starting from the top down I changed the Metroid to the Aberration typ, lowered the DR and energy resistances to 10, and raised the hit points to 53 using the standard 4.5 avg for d8s.
Then I changed the saving throws to match the new Aberration type.
I changed the bite damage to reflect its medium size, plus weapon finesse. I rebalanced the stats, reversing Strength and Dexterity, and lowered Charisma to 5. I applied skill points and feats. I removed the Attach ability and replaced it with the standard grab. I then remodeled the energy drain and transfer after the Vampire blood drain abilities. I also calculated its CMB and CMD, and added trip immunity since it flies.

Anyway, here's the stat block:

SPECIAL ABILITIES

Icy Paralysis (Ex) Whenever a metroid takes ice damage it must roll a fortitude save (dc 10 + damage done) or become paralyzed for 1d4 rounds. While frozen its energy resistances and damage reduction are negated.

Energy Vampire (Ex) A metroid drains energy at the end of its turn if it is attached to a foe, dealing 1d4 points of Constitution damage. The metroid heals 5 hit points or gains 5 temporary hit points for 1 hour (up to a maximum number of temporary hit points equal to its full normal hit points) each round it drains energy.

Energy Transfer (Ex) Instead of draining the energy from an attached creature a metroid can instead transfer energy to heal the creature. The metroid takes 1d4 points of constitution damage and the attached creature heals 5 points or gains 5 temporary hit points for 1 hour(up to a maximum number of temperorary hit points equal to its full normal hit points).

I dunno about Paralized. How about stunned? Wizards with ray of frost can Coup metroids all day.

[Kelandis]

Well, ray of frost will make the dc only from 12-14 I believe, so that's fairly easy to make with a +5 fort. You could probably drop INA for the feat that increases fort saves(cant remember the name for the life of me atm), or perhaps a more progressive freezing of the metroids. Perhaps treat it like an entangled condition where the metroid is able to either make a strength check or fort save to break the ice casing.

I haven't playtested it yet so any considerations are valid.

[Seth Dresari]

This was honestly the last thing I was expecting to see on this forum, but I like it so far. Will other types of metroids also show up, like Fission Metroids, Hunter Metroids, and the different stages of mutation of the SR-388 metroid?

[Seth Dresari]

I also think that Metroids, while still mostly running on instinct, should have the capacity to be very intelligent, and should also have the ability to temporarily grant energy to a creature in addition to the existing energy drain capabilities. Because, you know, that one scene near the end of Super Metroid.

[clff rice]

Look at the original post. The metroids can transfer energy to others.

[Seth Dresari]

Oops, I didn't notice that part.

I think their energy drain needs to be reworked a little bit, and I also think their damage resistance shouldn't be 15/-, but 10/cold or 10/magic or something. If you have a powerful enough weapon, you can kill it without freezing it (as is evident in Metroid Prime). Just keep pounding, and it'll eventually explode.

Of course, there are different varieties of Metroid.
There are the Metroids from the Prime series, which I consider the "normal" kind, and there are the SR388 Metroids, which mutate into Alpha/Gamma/Zeta/Omega stages and grow to larger sizes.

Then there are the Fission Metroids, which split into multiple Metroids of you try to kill them with the wrong element.

Then of course, Hunter Metroids and Hatcher Metroids... And Dark Metroids, if you're into that kind of thing.

Finally, there would be Metroid Queens and the Metroid Prime as boss monsters. Be careful around the Prime, for it might turn into a Dark doppelgänger of whoever kills it.
