The story behind this picture, as explained by ~zwoots
say that the Charizard's name is Jimmy McTittybong.
He used [to be] a young, pink female pony and his old name was Beethoven the 3rd.
She was bullied by rainbow dash for being named after Beethoven who, in pony world, committed genocide against frogs.
So one day, after coming home from school, Jimmy comes across a frog. The frog says, "wow you're so politically incorrect.
The frog then casts a spell meant to kill the pony, but the spell goes horribly wrong and turns her into a male charizard instead.
So then, being a male charizard, his teasing powers increase by 100000.
Using his new powers, he changes his name and teases rainbow dash until she dies of humilation and teenage angst.
The frog, having very short memory, forgets about the entire event and hops away into the sunset, snorting lots of cocaine as he does so.
Drawn in my livestream because haha Rainbow Dash how do you like it now?
