Krakatoa

"Prr..."

The Trent Labs located on Bloop Town, a place that would scare even the most fearless warriors. The task of today: a risky attempt at combining an unidentified reptile's skeleton with volcanic rocks and around 10 liters of an orange acid that was not described before doing this dangerous experiment. After letting it all mix in a special container for 2 hours, the baseless idea had found a definitive result: Krakatoa.

Krakatoa is an unknown creature with reptile traits and a shell made out of black volcanic rock, in wich two severely small volcanoes are what attracts more the attention of those who see him. Since his first appearance in the Labs, he has been working as an assistant to Julia (mostly just carrying boxes, but it's something). He is very affectionate towards people he likes, but is impatient and very easy to get angry. When he gets angry, his volcanoes are more prone to letting out flares or straight-up lava, so he has to be approached with care. At some point, it got known at the lab about that Clara's girl idea of going into an adventure, and Krakatoa eagerly offered to accompany her himself. There wasn't going to be much of an impact, so he was allowed to.

He can breathe fire to attack and can withstand extreme (hot) temperatures, but one can easily tell at first glance his main ability is in his volcanoes. He can choose to erupt them at will, but loses control of them when hit with heavy emotions such as the aforementioned anger. He doesn't have actual lava inside him, the eruptions and all else consist of a boiling hot liquid that only assimilates the real thing.... or so says Trent Labs, at least!
