Ogres

Ogre evolved from a Goblin.

Evolution
Ogre
 * Ogre Shaman
 * High Ogre
 * Ogre General
 * Ogre King
 * Oni: Unique species, raises Taboo upon evolving. Has a human-like appearance

According to Wrath the most notable differences in Ogre's evolutions are the sizes. With each evolution, the size of the individual increases. If the individual chooses to evolve into an Oni from Ogre General, the individual will decrease in size, but gain considerable power.

Trivia

 * Presumably, Ogre's evolution options just like Goblin's are Ogre Fighter, Ogre Ranger, and Ogre Shaman.
