## Powers

* Ouroborosaurus has a healing factor, allowing him to heal himself from having mercury poisoning.
* Ouroborosaurus' spikes have healing properties, as seen when he put his spike to Jessica's leg wound, healing it.
* Although he had to heal himself from mercury poisoning, Ouroborosaurus himself is immune to mercury, as he had no problem regurgitating the mercury, and also was not affected by the mercury that got on his spike after healing Jessica's wound.
* As revealed in *RWBYA*, Ouroborosaurus has a pacifying aura. This makes it so that enemies that get too close will no longer decide to fight him, allowing for a much easier time healing.

## Weaknesses

* Ouroborosaurus' aura can be bypassed, should the enemies keep a distance from him and use ranged attacks.

## History

### *The Alan 10 Adventures*

#### Actually Used

 *RWBYA* Part 3 | Ouroborosaurus appeared to heal Blake's stab wound given by Adam. He also healed himself and temporarily knocked down Adam.Ouroborosaurus was one of many aliens used to overwhelm Cinder Fall with the power she was absorbing. It is likely this appearance was also used to heal Alan of the mercury given to him by being Mad Hatter. | Alan Nomaly | 2

## Etymology

* Ouroborosaurus' name is a combination of the words "ouroboros," a symbol of cyclicality, usually represented by a reptile, such as a snake or dragon, eating its own tail, and the suffix "-saurus," primarily used for dinosaurs.
* Ouroborosaurus' species comes from the Latin words "mortuus est," meaning dead, and "piscinae," meaning pool, as a reference to the Marvel anti-hero, Deadpool.
* Ouroborosaurus' planet name is the word "homunculus" backwards. This is a reference to the Homunculi from *Fullmetal Alchemmist: Brotherhood*, which can easily heal themselves.

## Trivia

* Originally, the species Mortuus Est Piscinae was called "Curedium," being a mix of "cure" and "carbonadium," the latter being the only substance to ignore the healing factor of characters like Deadpool and Wolverine. This, paired with the prototype planet name, Cancare, was created as a joke, parodying how *Ben 10: Alien Force* had retconned Kevin Levin's mutant origins to be an alien, and Gwen Tennyson's origins from magician to alien. The joke was that, had characters like Deadpool shown up in the franchise, the mutant/mutate origins would be retconned to be alien.
	+ The species were also at one point going to be Mutantem, a play on the word "mutant" and the Latin word "elementum," meaning factor.
* Ouroborosaurus' design is based on Zilla from the 1998 *Godzilla* movie.
