Boss Rush

All of the past 6 bosses all into one! They all have a million hit points and run faster then you. They cannot hit each other, and you have three guns, and a Ultima Weapon. Xemnas clones return, battle field is invisible like the one in the Xemnas boss, but bigger, and same background as the Xemnas boss. Can you last long enough? Or will you just give up? 10 players allowed max. You should have 2000 HP.
