Lava
Lava is based off of my love for lava cake. Yes, that's literally what he's inspired by. I love lava cakes so much that I made a character based off them.
He is sweet most of the time. You know, lava cakes are very chocolately and sweet, so that's why he's sweet. But, since his name is Lava, he has a short temper. I would advise you to not get on his nerves.
