Ultimate Brainstorm is a blue-tinted metallic-skinned crab-like alien. He has eight legs with two massive arms holding elongated pincers funneling electricity between them.
The Ultimatrix symbol is located on his torso.
- Rail Gun Projection- Ultimate Brainstorm's headplates press down on his brain to funnel the energy to his claws to fire a powerful rail gun attack.
- Electrokinesis- Ultimate Brainstorm can control and disperse electricity with even more potency than his unevolved counterpart.
- Durable Exoskeleton- Ultimate Brainstorm's copper-based skin is very durable.
- Low Intelligence- The heightened electrical abilities of Ultimate Brainstorm come at the cost of a lower intelligence due to his headplates pressing down on his brain.
