elf, golem, and beholder

Elves are excellent archers, although they have almost no chance against dragonflies. I also think they were drawn best in the third game (both the regular and upgraded versions, even without cloaks or hoods).
Golems have a lot of HP, good defense, and are just likable. They are good in all parts of the game.
Beholders have something special about them, and they can even fight well in melee. Maybe they can even defeat a dragonfly.

Orcs have a great appearance.
