Clione & Beartank from Rakuga Kids, by Konami.
A bit unorthodox, Beartank’s closest comparison would probably be Guilty Gear’s Faust. The kind of character that excels at constantly throwing your opponents off balance, I guess. He’s also quite the combo king.
If Beartank seems familiar but Rakuga Kids doesn’t, you might recognize him from his nifty cameo in Castlevania: Circle of the Moon, or possibly from the underrated Konami Krazy Racers.
