I suppose the Ex characters could be considered balanced to other Ex characters, but there aer some (Robo-ky, Testament, Dizzy, Jam, Order Sol, Slayer) that I noticed are too spammable (for those who don't know: it means you can almost guarentee victory by using just two or three moves over and over.) to be used against normal characters. (unless you are near perfect with your character of choice! or the Ex player is a noob.) There are some thought that I wold go as far as to say they are balanced against the rest of the cast.
