I was thinking that the Power Ponies must have actual designs, so I thought, hey, what if the Power Ponies real designs were some of the toy designs. This is Flitterheart (http://mylittlewiki.org/wiki/Flitterheart)  
Flitterheart is an ordinary guidance counselor in Maretropolis with a dark secret. She was born sickly and weak, and doctors didn’t believe she’d survive. Her parents searched everywhere for a cure. Their travels brought them to a shady potions dealer as a last resort. The potions dealer offered them a mysterious potion that she said would make Flitterheart grow up big and strong. The potion worked wonders, but it came at a cost. Soon they discovered Flitterheart would change into a monster when mad, after she threw a tantrum as a foal. Her parents tried to raise her right despite this, and as a result of her fear of turning into a monster, Flitterheart repressed anger, resulting in her meek demeanor and quiet nature. She works as a guidance counselor for fillies and colts at Maretropolis Public School. She first used her strange powers to fight evil when the Mane-iac attacked her school, she hid away, but transformed when the Mane-iac foalnapped a colt. She put on a mask and cloak over her hulking body and chased after the Mane-iac. When she arrived at the crazed mare’s hideout, she found that she was not alone in the fight, a masked mare who called herself Radiance. They teamed up on the Mane-iac and saved the colt. Now, she’s joined the group of heroes Power Ponies as the Saddle Rager. She usually plays little role in the fights, as she isn’t quick to anger, but the second her friends are hurt, she’ll jump into action. First appears in issue 3# “Saddle Up, Flitterheart!”
