Way Big (Earth-73)/Timeline 1

Way Big is the Omnitrix's DNA sample of a To'Kustar, a race of gigantic aliens from the Cosmic Storms.

Curtis as Way Big
Way Big is a colossal humanoid creature with a large fin on his head, which is red at the front and black at the bottom. He has blade-like growths on his shoulders. He has blue arms with two black lines and white fins on the elbows. He has wristband like outgrowths on his wrist and has blue eyes on his head. He has blue feet with a boot-like design and a line on the side of his neck. He also has a stripe running down his chest, with the Omnitrix residing in the middle of the stripe.

Bad Curtis as Way Big
He as the same design as Curtis as Way Big but the is replaced with purple and the red replaces the blue.

Powers and Abilities
Way Big is very strong (even for his size).

Way Big has great durability, withstanding attacks from enemies while barely even feeling them.

Way Big can shoot a cosmic ray similar to the Ultraman signature technique Specium Ray. He does this by crossing his wrists together, with his right forearm vertical and left forearm horizontal in front of it and the thumb edge of his hands facing his body, to shoot from the outer edge of his right hand a powerful pale orange ray. He sometimes performs this attack by crossing his arms in an X shaped pattern.

Way Big can survive in the vacuum of space and in extreme temperatures.

Although he hasn't trained himself to do so, Way Big can create and control cosmic storms, which can also be used for inhabitation and transportation.

Weaknesses
Way Big often forgets how strong he is. 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.

Way Big's fin is a weak spot. A hit to that area can paralyze him, transforming him back to Curtis.

Despite his immense durability, Way Big is vulnerable to opponents with sufficient strength, such as an another To'Kustar.
