But like I said, the additional boxers would make good assist trophies. It's unfortunate that Punch-Out!! currently doesn't have an AT because there's lots of potential options to choose from:
Glass Joe: obvious joke assist trophy, who wimply throws out weak punches and gets KO'd far earlier than the other assist trophies
King Hippo: big and powerful, but the catch is that he can only be KO'd by hitting his weak point on his stomach
Great Tiger: teleports around the stage, distracting and tricking opponents with his Rushing Magic Attack
