Ultimate Way Big

Ultimate Way Big is the evolved form of Way Big.

Appearance
Ultimate Way Big is similar to Way Big but the black parts of his body are changed to blue and he has 2 horns in the left and right of his fin on top of his head, similar to Alien X's. He is also shown to be bigger than his original form, about 3 times bigger than Way Big.

Powers and Abilities
Ultimate Way Big is extremely strong, able to throw Diagon to the ground, who was colossal at the time.

Ultimate Way Big has the ability to fly.

Ultimate Way Big can fire a more powerful version of Way Big's cosmic ray, as well as Cosmic Disks.

Ultimate Way Big's super speed has been enhanced, allowing for him to run and/or spin at super speed to deflect attacks.

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 couldn't bear the acid rain brought by Diagon in The Ultimate Enemy: Part 2.
