Brianna is Teri Forman's best friend. In the episode Toothache, it is shown that she doesn't really care much
for biology and would much rather sleep. She is on the cheerleading team. She is portrayed by Camille Spirlin.

She wears braces and works at Burger on a Bun. She is shown to be on the cheer squad. She knows that Marvin is an alien and swears to keep it a secret. She is a vegan. She is generally kind and sweet, but can stand up for herself at times.

She later found out that Marvin's an alien (though she didn't belive him until he transformed)
