He looks like 11-year old way big but with blue fins.
XTRALARGE is very strong (even for his size.)
XTRALARGE has great durability, withstanding attacks from enemies while barely even feeling them.
XTRALARGE 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 green ray.
Way Big can survive in the vacuum of space and in extreme temperatures.
