Mad Ben is an alternate and evil version of Ben Tennyson.
Mad Ben now wears a black leather spiked-jacket with it's left arm torn out. He wears a silver shoulder patch marked with a 10 on his left shoulder, orange gloves and a bracelet-like Omnitrix on his wrist, which he calls the Power Watch. He wears brown pants and black boots.
Mad Ben has an Australian accent and tends to speak in a calm and cool voice and uses catchphrases akin to those of fierce and cool-headed movie characters.
Mad Ben is extremely bloodthirsty, megalomaniacal, sadistic, spiteful and power-mad towards his subjects in his dimension; he reacts with extreme aggression and threats whenever anyone else at all so much as talks to him as an equal instead of his servant, and after Maltruant left, Mad Ben still had his exhausted and half-dead slaves keep digging for no reason.
Mad Ben apparently thinks highly of himself as having achieved glory by becoming a tyrannical warlord, and contemptuously thought his heroic alternate counterparts to be too "pathetic" to ever be like him.
Mad Ben is also very short-tempered and becomes hotheaded when insulted or irritated, which can both serve as his weakness and serve to make him even more dangerous. He apparently doesn't react well to defeat or humiliation either.
Powers and Abilities
In combat, just like every other Ben, Mad Ben relies on his Omnitrix, which is also known as the Power Watch. He appears to have much finer control of his Omnitrix compared to Prime Ben and Ben 23, as he was never seen mis-transforming.

Like Ben Prime, whenever the Power Watch times out, Ben is left powerless until he either dodges or switches to a new alien form, although he is highly trained in combat. In addition to gaining the selected alien's powers and strengths, he gains its weaknesses.
After using the Ascalon to defeat Vilgax, Ben had the opportunity to take a decision on something that would not only affect him but maybe the rest of the world. While thinking about what to do, his friends kept telling him to do what's right, but Ben had enough.
He didn't want to do what's right, he wanted to do what he wanted for him alone, for the first time in six years. He then used the sword to turn the Esoterica back to humans, just to alter reality by his own, making it a dystopical world. As it detected a negative wish, Ascalon dematerialized from Ben's hand, angrying him. But he also changed some other things.
He remembered what Azmuth told him about not being worthy of The Omnitrix. Well, now he made himself worthy to be the weilder of the universe's greatest tool. Or, in his hand, a weapon. And he will rule with an iron fist.
