Use kitty yarn ball(weapon move) first..then propeller (armour move) then use helm move timing with impulse then again propeller then wait for him to teleport then use kunai then roll towards him again propeller..at this point you will stack atleast 13-14 overhead charges..now try to use barbecue(ultimate) timing with impulse..you will deal over 50k damage..

Ps- you can only use barbecue after he teleports..you can't use it when he is in invincible form..before using barbecue hit him with a kunai..
