Converting Yu Yevon into Pathfinder

[Kaelan Ashenveil]

So I have been replaying FFX, and realized that Yu Yevon is the poster child for synthesist summoner. Yevon wears his aeon (eidolon) as unholy armor, and can create more mooks to fight (sinspawn).

While I realize that even Synthesist Summoner isn't as brokenly OP as Sin is, how would one go about converting him?

Sin would be a base Aquatic, with magic flight evolution, improved nat armor, poison (Sin's Toxin), frightful presence and size?

Was struck by inspiration, and did it. It's a 36 pt Eidolon, made possible by 26 from level 20, 5 from Extra Evolution feats, and 5 from Half-Elf favored Class Bonus. This is off of an Aquatic base.

Here are the evolutions:

Improved Nat Armor x2
Limbs
Slam
Tail
Tail Slap
Large/Huge
Flight (5 points to make it magic and expand it to 40ft)
Poison
Frightful Prescence
Breath Weapon (What it did during Operation Mi'ihen)
DR 10 Lawful (or good... I guess)

Nice. I just picked up the remastered FFX/FFX-2 and replayed them and was talking about pathfinderizing some of the monsters and characters with my husband. I'll have to show him this. I think building some of the summons could be cool, especially Anima.

I also just picked that up. Mostly why I was thinking of this myself.

But I just ran the stats, and "Sin" would end up a 48 Str 24 Dex/Con Huge flying Armored monster with +8 Nat Armor. And "Yevon" would still be able to summon more Sinspawn the whole time.

EDIT: I think I'll be making the rest of the Aeons for summoners for a campaign I'll be hosting shortly. I'm looking forward to my PCs fighting Ifrit xD
