Ronimo Games introduced its 13th character to Awesomenauts, and his name is Genji. Genji is one of the last living Entin, a caterpillar-like monk "on a pilgrimage to restore his faith in the great space butterfly."
He is also a support character that specializes in "shielding allies and banishing enemies." Ronimo tells us that Genji is being put through testing in closed beta, along with a sizable balance overhaul for the game, so there's no specific date for when the character will join the rest of the Awesomenauts crew. The official site for the game lists him as a Steam exclusive, though.
