I feel that metal powers on a taunt would be imbalanced. It doesn't really fit, either.
this why you take 30% dmg and i will try to do so you can´t spam metal mario taunt too so you can only do it 1 time per 2min
or like my Shadow-kong´s chaos control
if you got much dmg you can do it but still takes dmg for using it
or i will do so up-taunt is a Random Mario item taunt
Mushroom(Super and postion too)
metal box
but that idea i dont think so i think metal box after got much dmg is best
btw i am back
and stronger then ever
(PC fixed and hopefully soon SMBZ mario´s FS so i can code my ide for metal mario and the other things)
offtopic: got new sign. with both Gotenks/Mario
