Junior is one of the three members of The Amoeba Boys. He is a short round Amoeba with a gangster affectation. Junior is based loosely on James Cagney and Al Capone, he can be decribed as the little one. He wears a black cap and usually repeats whatever Bossman says. Like the other amoebas, Junior would love nothing more than to be regarded as a serious villain worthy of fighting, and even getting beaten up and sent to jail by the Powerpuff Girls. Unfortunately, his brain is far too primitive to devise a crime above the level of littering or jaywalking. He is definitely one of Townsville's least malicious villains, even having a friendship-of-sorts with The Powerpuff Girls. He is generally harmless, but his actions have on several occasions endangered both the girls and the town purely by accident. Juinor acts much like Bossmans Yes-Man, repeting things he says to add emphases, he has also shown the ability to regurgitate a wide varity of objects, such as Paperclips and a Basketball.
