Bulla is from the Dragonball-verse and is the daughter of Vegeta and Bulma. She's an extremely friendly person who deals with grumpy people reasonably well, and she's a little tank due to having half-saiyan abilities. She's on pleasant terms with Dante and will be nice to Nero unless given reason not to be.

I also have Hellmaster Phibrizzo (brat_from_hell). He's the 5000 year old lord of death and the afterlife in his canon and takes a child's form. He loves to troll people on the network because he feeds on negative emotion.
