Yeah, it's the Wario Land 4 version of the character. Honestly, I'm impressed. Would be neat to make a ROM hack based on this moveset whenever it gets released:
Each subsequent Wario platformer (1994-2004) kept pushing the envelope with the weirdness and crudeness. In a way, Wario World is the grand finale and peak of how weird a Wario game's atmosphere could get.
I agree with CM30 on this one. Though I admit Wario World was closer to the original Wario Lands in terms of how crude it was artistically, even though it was much more exaggerated.
That's amazing! VB Wario Land has amazing sprites and animations. Such a shame it was stuck in monochrome VB hell! But not anymore it seems! It actually makes wanna play it again.
