Due to being in explosives, Sulfur likes to explode things. She drags her S's when pronouncing them. Although she is used to being called Sulfur, she doesn't mind being called Brimstone, which is her older name. Sulfur used to bond with Thallium to create rat poison before he moved on to making safer things. She is part of Team Sponch, along with Phosphorus, Oxygen, Nitrogen, Carbon, and Hydrogen. As Brimstone, she retains the same personality, but is also evil.
Drags her S’s (“suh-SUL-fur”), talky-rhymed outbursts, sudden stops like a fuse lit; loves quick threats in jokes.
