Molten Kitteh/Backstory

One day, Stormy Kitteh and Joyful Kitteh went on a walk together in Stormy's universe.
Joyful Kitteh: I'm loving this fresh air!
Stormy Kitteh: Me, too, but maybe we should explore a location more unique.
Joyful Kitteh: What about the caves?
Stormy Kitteh: Great idea!
Stormy and Joyful went into a cave. Many tarrs got in the way, but Joyful Kitteh's joy aura made them too happy to attack. The two deities eventually got close to the mantle of the Far, Far range. They made it down there, and sat right above it. It was scorching hot down here, but Stormy Kitteh created a magic, translucent cloud with cold air and vapor. This surrounded the two deities.
Stormy Kitteh: I really wonder what's below the mantle. However, I think we can find that out later.
Joyful Kitteh: Yeah.
Stormy and Joyful relaxed a bit... A bit too much. A couple sparks came out of Stormy Kitteh and hit the mantle. Then, a shape started forming in the mantle where the sparks landed. It was the shape of a tabby slime.
Joyful Kitteh: Ooh are we getting a new friend?
Stormy Kitteh: Oh. Oops.
Joyful Kitteh: This is a good thing!
A red-orange tabby slime emerged from the mantle.
???: WHERE AM I? AND WHY AM I FACE TO FACE WITH SOME DIFFERENT COLORED TABBIES?
Stormy Kitteh: Hello! Who are you?
???: I'm Jake. Duh!
Stormy Kitteh: Yeah, but your new name is Molten Kitteh. Well, if you prove you're worthy of being a god.
Jake: Kitteh? God? Proving I'm worthy? What are you even talki-
Tarrs: A red-orange tabby slime! We've never seen any of those before! CHARGE!
Jake: OH, I'LL PROVE I'M WORTHY!!
Jake turns into a fireball and charges through the tarrs, incinerating any that touched him. He then turned into lava and slid into a crack in the rocks.
Stormy Kitteh: Let's make a boss for him to fight!
Joyful Kitteh: What about a Tarrlossus?
Stormy Kitteh: Lunar already fought that kind of boss.
Joyful Kitteh: What's wrong with repeating the same thing?
Stormy Kitteh: You're right. And besides, we don't have any time to decide!
Stormy and Joyful went to the surface, and a Tarrlossus appeared. Jake came out of the ground and started throwing fireballs. The Tarrlossus tried to grab Jake, but he turned into a fireball himself and dodged. Then he tossed a ball of lava that melted a tentacle of the Tarrlossus. The Tarrlossus tried to grab him again, and succeeded, but Jake just melted again and reformed on the ground. Then he rapidfired fireballs until the Tarrlossus started bashing him to death. He cried out a bit of lava, which burned and confused the Tarrlossus. This gave Jake time to crash right into the Tarrlossus as a fireball. The Tarrlossus roared in pain and rage, and Jake melted more tentacles by throwing globs of lava at them. Eventually, the Tarrlossus collapsed into a puddle of goop, and Jake felt more powerful than before.
Jake: You call that a challenge? That was easy!
Stormy Kitteh: Good job! You are now a god, also known as Molten Kitteh!
