ULTIMATE GRAVATTACK: is the evolved form of Gravattack.
Ultimate Gravattack no longer has legs, and floats entirely by manipulating his gravitational field. His skin crust becomes more jagged, as crests and peaks form on the surface. His planetary core is engulfed in his mouth now, with a red spiral circling outwards. His hands are much larger than Gravattack's.
The most notable change, however, are the three smaller orbiting planetoids that spawn around him, caught in his gravitational field. They each have a little face on them that resembles Gravattack's original form in orbit mode.
POWERS AND ABILITIES
Like his devolved form, Ultimate Gravattack can control gravity to manipulate weight of objects, motion of objects, or slam them down to the ground with ease. Ultimate Gravattack can make matter or energy orbit around him. He can also manipulate his own gravity in order to levitate. Like Gravattack, his three smaller orbiting planetoids also have gravikinesis. Being made of rock, plus his naturally large size, he has enhanced strength and durability. The long, pointy mountain peaks on his head and arms could easily be used as a sharp weapon.
Ultimate Gravattack's large size makes fitting in smaller spaces difficult.
Because he has no legs, Ultimate Gravattack must use levitation on himself via gravikinesis, in order to be mobile at all.
