Doctor- This popular do-gooder exists solely to help people. S/he has no weapons, but comes with the powerful Med Kit, an item that mends friendly hearts for the low-low price of a single battery. The Gloop Angel queen on the Doctor's Gloop side flies around giving friendly aliens an armor bonus.

PROS: Great team player. Gloop Immunity can really wreck an alien's game.

CONS: Not much of a fighter. Gloop Angel sometimes won't be worth evolving two glooplings.
