i would say you should beat the last boss. i do not know him. i NEVER beat 13 bosses in the arena. it was tricky, that's why. your welcome!
You choose the helper you want to battle with (I would suggest bonkers or bio spark) and you fight with them. You have to fight each boss until you get to wam bam jewel then after you beat him you win! Good luck beating helper to hero with every single helper (You get a special reward) :D
