In case you didn't know what the different Titans are like, here:
Ulamog is mostly humanoid, only he has more hands and no face, and tentacles. It warps the physical properties.
Kozilek is partially humanoid, with a very small or nonexistent head, and plates of bone or rock floating above it. Also tentacles. It warps reality.
Emrakul resembles most closely a jellyfish, with most of its body being tentacles that fuse into a mushroom-like structure on top. It warps creatures' biology.
This goes into more detail, and is more accurate.)
Beyond my infamous Quo'aqo (Who warps intelligence), what other types of titans would there be? What would their brood look like? Cards are welcome, but this isn't a contest.
