Ultimos

Ultimos is the leader of the Galactic Enforcers and the most powerful hero on the planet T-K. He first appears in The Galactic Enforcers. Ultimos reappears at the beginning sequence of Vengeance of Vilgax.

Abilities
Ultimos's primary powers are superhuman strength and invulnerability, flight, heat vision, and ice breath. He is very similar to Superman in terms of his powers, appearance and attitude. He lost his powers in the Ben 10: Alien Force episode, Vengeance of Vilgax: Part 1 because of Vilgax.

In Ben 10,000, he still has his powers, this is in an alternate timeline, meaning that Vilgax never stole his powers in that timeline or he did and Ultimos recovered.

Weakness
Ultimos' "Kryptonite" is chocolate. It turns his skin to a brownish gray color, makes him cold, shiver and collapse, and becomes skinnier when eaten. Synaptak identified that a specific chemical in chocolate is poisonous to Ultimos and his species.

Original Series
Ultimos showed up in The Galactic Enforcers to help Ben defeat Sixsix.

Alien Force
Ultimos lost his powers to Vilgax after he was defeated by the latter. It is possible that Ultimos, Tini, and Synaptak died after losing their powers.
