Hulk Apollo

Hulk Apollo is a villain in Death of Ben 10. He first appeared in Chapter 15. He is a Pyronite from the planet Pyros. He is an alternate version of Apollo from an unknown dimension.

Appearance
Ordinarily, this version of Apollo is by far the scrawniest of the alternate Apollos summoned in Chapter 15. He resembles his prime counterpart, but thinner and sans the shoulder volcanoes.

Personality
Hulk Apollo is a coward, often seeking to avoid conflict lest he unleash his terrible power.

Powers and Abilities
Hulk Apollo possesses all of the standard abilities of the Pyronite species.

Additionally every time Hulk Apollo takes a hit that he can recover from, he gets stronger. This effect makes him bigger, tougher, and hotter. He can be defeated if he is knocked out or killed quick enough to nullify the effect of this ability, however this gets harder the more hits he takes and survives.

Death of Ben 10
Hulk Apollo was summoned by Apollo to fight the alternate Bens in Chapter 15.

He fought Ultimate Ben 10'000 in Chapter 16: Part 2. Even though Ben figured out why Apollo was getting stronger after each hit, he failed to beat him alone. Ben 10'000 showed up and helped defeat Hulk Apollo by using Tickin' Clock to undo Apollo's gained strength -making him weak enough to beat.
