Way Big is a To'kustar from no planet in Ben 10.
He is a big white and red humanoid who has a fin and yellow eyes. He wears the prototype Omnitrix symbol on his chest.
In Alien Force and Ultimate Alien, he has green eyes and he appears slightly different. He wears the prototype Omnitrix/Ultimatrix symbol on his chest.
In Omniverse, he he has three red lines on his neck. The blades on his shoulders have returned and he also has fingerless gloves, similar to the ones Four Arms wears. He now has eyes on his cheeks again. There are also blades on his waist and front thighs. Both 11-year old and 16-year old have this appearance.
Way Big is very strong (even for his size), as shown when he defeated Vilgax (who was Way Big's size at the time) and threw him into orbit.
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 blue (green in Omniverse) ray.
Way Big can survive in the vacuum of space and in extreme temperatures.
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.
It's revealed in Ben 10: Destroy All Aliens that Way Big's fin is a weak spot. A hit to that area can paralyze him.
