Barrier Reef (Earth-1010)

Barrier Reef is the Omnitrix's DNA sample of a Coral Titanoform from the planet Aquillis in Earth-1010.

Appearance
Barrier Reef is a large humanoid creature with a body made of a coral-like material. His body has many sharp edges on top, and the Omnitrix symbol is on his forehead.

Powers and Abilities
Barrier Reef's most notable ability is his ability to generate barriers of energy either around himself, or projected around someone or something else. These barriers can withstand a huge amount of damage but are not totally invulnerable, though the actual damage required to break through them could crack a small moon in half anyway.

He has highly enhanced strength and durability, as is befitting of his shape, size, and body composition.

He can breath underwater, though he cannot swim as he is too heavy.

Somehow, Barrier Reef possesses the ability to detect when nearby coral is in danger.

Weaknesses
Being effectively made of coral, Barrier Reef is vulnerable to high levels of stress, which are capable of killing him. Whilst he is fine in most situations, things that can induce heightened levels include being exposed to elements outside of his comfort zone and being put into situations that overwhelm the user.

Barrier Reef is vulnerable to sonic attacks, as they can also highly increase his stress levels.

He is also vulnerable to the cold. Being exposed to the cold does not stress him out, but it does slow him down and potentially force him into hibernation.

Barrier Reef's shields do not prevent changes in temperature from passing through via convection or conduction. Heat distributed by radiation is still blocked, though.

Death of Ben 10
Rocky Blocker was used by Ben 23 in Chapter 11 to save Ben Prime from Apollo's fire. The shield prevented Ben from being ignited by the fire, though most of the temperature still went through it was not enough to kill him.
