maybe you can have a special option (like capture the dragonball)that you work with two (you chose your partner at the beginning of the match and if you have a partner you have to go searching for the fussion earings and then if the team is like vegeta and goku they fusion into gogeta and there power will be multiplied 4times and then they play the game stronger and faster then everybody . with other words you have to chose a partner at the beginning of the game you fight your way through until you two find the earings pick them up go stand next to eachother then press w and fusion and then wile in fusion you can transform again (ssjgogeta) and again (ssj4gogeta) anyway thanks for reading this
