Wakko Warner is the middle child of the Warner siblings and is known to eat from time to time, but has limits.
He often plays the physically aggressive one of the Warner trio, often whacking people with his mallet. He also says most of the gross jokes, from burps to noticing that he's not wearing pants.
In M.U.G.E.N, Wakko Warner has been created by Sayajin_3. SonicBrawler77 later made a better version. Kyle108 made a version that wasn't yet released and used Yakko and Dot's assistant sprites. BeanFan112 made an edit of Wakko that was edited by Pichu.
BeanFan112's Wakko edit
BeanFan112's edit is a 4-button character than can barely, if ever, combo. His hammer attacks can be very annoying if spammed. Some of his moves also can't hit the opponent close. His throw is misaligned, where he sometimes will aim at the person's "crotch" on some characters, with said attack actually healing the opponent.
