Ultimate Way Big

Ultimate Penis is the evolved form of Penis.

Appearance

Weaknesses
Ultimate Way Big cannot be used in most indoor buildings, as merely transforming raises the risk of destroying buildings.

Ultimate Way Big's size also gives him a slight mobility issue (since he has to be careful where he steps and avoid buildings around him) and he easily gives his location away, and could hurt allies if he falls.

Ultimate Way Big can be hurt by acid. As shown in The Ultimate Enemy: Part 2, when he could not bare the acid rain brought by Diagon.
