Ultimate Way Big is similar to Way Big but the black parts of his body are changed to blue and he has 2 new horns in the left and right of his original horn on top of his head, similar to Alien X.
Powers and AbiltiesEdit
Ultimate Way Big is shown to be extremely strong, he has the ability to fly and to shoot a more powerful version of his cosmic ray, and his super speed is shown to be increased.
Ultimate Way Big cannot be used in most indoor buildings, as merely transforming raises the risk of destroying buildings since Ben has to transform into regular Way Big first.
His 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.
