The Makluan Berserker is the strongest gladiator of the Makluan race.
History[]
When Iron Man, War Machine, Rescue, and Gene Khan defeated the best Makluan gladiators, their overlord released the Berserker. At first, they were overwhelmed, but Iron Man detected his weakness in his energy levels. Iron Man took his hammer while War Machine and Rescue fired their unibeams to overload the Berserker and defeat it.
Powers and Abilities[]
The Berserker is larger than his race's normal size, at least as large as four buses stacked on top of each other. That alone makes him tremendously strong and he can just as easily take serious punishment.
In terms of unnatural abilities, this draconic behemoth is somewhat similar to Ultimo, in that he was capable of absorbing any sort of energy (namely kinetic) and metabolizing it as indominable power to go with his own strength. However, unlike Ultimo, instead of converting energy into mass, he builds up an earth-shattering charge that he can release through a single strike of his hammer. All that strength, power, and durability paired with his warrior training makes him impossible to defeat with sheer force.
His only conceivable weakness is the very thing that makes him so powerful. Specifically, he may be able to absorb huge amounts of energy, but there's a limit to how much he can hold. That's why his hammer proves absolutely essential in battle as it is the only thing that can release all that energy - serving as an exit valve as well as a concussive weapon. In the event he were separated from it and unable to reclaim it, all the unstable energy he's built up would have no way of releasing and more concussive or energy-based attacks against him would just keep leveling up the energy mass until it reaches its breaking point. And when it does, the energy will release in a violent explosion, leaving him catatonic.
