Devilites and Soul Jellies first appeared in Underwhirled Drift, but there is a third character that seems like they missed: the Pit Brute. I wondered why OOO did not add Pit Brutes to the game, but recently I realized there's many visual similarities between the Pit Brute and Lord Vanaduke. Perhaps Vanaduke is a Pit Brute? Did anyone else notice this?
I am pretty sure Vanaduke and Krogmo share more similarities than Pit Brutes. The only similarity I see is that that they have pointy teeth chin/mouths and stocky bodies.
