Charco REX, Awakening ("Charco REX, Kakusei")
By accepting the aide of the ancient spirit, Rex, Charco can tap into the nigh boundless power of the Tyrannosaurus who once nearly drove humanity to an early end. This power is not without risk, however, as the spirit uses it to try and erode the will of his host until the entity can fully possess them, regardless of their consent. As of this current time, Charco can raise his power (5x) his usual base power level before Rex's influence becomes a threat, although the latter will always offer the temptation of going beyond this limit.
Only the STRONGEST Survives
The innate ability of Rex which had allowed the dinosaur to survive the savage conflicts of an early world. By consuming anything possessing energy, whether it's a destructive ki technique, or the flesh of a living creature, Rex, and by extension, Charco while under the influence of the former's power, can replenish their energy reserves, heal injuries, and boost their power, depending on the state of their being before using this ability.
Atomic Breath ("Genshi Kokyū")
A technique developed through the combination of Charco's ability to catch and release foreign energy (such as the KameTyrannoHa) and the ParaSHOUTolophus. By performing the latter in defense of an enemy's ki technique, Charco can shape and expel the energy back with a roar of destruction.
Yucatan Crash
Long ago, before humanity's rise, a being from another universe named Yucatan approached Earth with the intention to judge its population. Determining the beings of Earth guilty, this God of Destruction sought to destroy it but found an unlikely defender: a dinosaur named Rex. Although much more powerful than this beast, Yucatan's arrogance would prove to be his undoing as the dinosaur defeated and ate him, absorbing his destructive Hakai energy. Perhaps as a result of Rex's immortal death or how the energy was digested, Rex or a host under his influence, can summon the energys of death, misery, hatred, and other negative emotions from the world and its population into a sphere of pure destruction. Much like a similar technique to it, the Spirit Bomb, collecting this energy takes time, but isn't it worth savoring the results?
