Name: Ambrosia
Alias: Saddle Rager
Power: Her anger personifies as a huge raging monster she can turn into.
Weakness: Her powers only work when she’s angry, so if a villain can manipulate her emotions, she can’t turn into her rage form. But when she is in her raging form, not only is she hard to calm down, but she's also like a stampeding elephant; big, makes a lot of damage, and is hard to direct. The team and city run the risk of getting in her way and being trampled if she ever went too far.
About:
Her family are very high class, with both a cloud home and a land home. They send her to Boarding School to get rid of this anger of hers, but that only causes it to be repressed, it's not gone, and it has had years to grow inside her.

During a freak storm, 5 ponies are struck by lightning and gain superpowers.
Ambrosia was in Central Park when the lightning struck her. She had just had a fight with her parents and had ran off to vent and cool off. Her anger manifested itself into a monsterous raging form and she proceeded to trash the park until she calmed down.
