Firecracker Burst, Equestria's mad bomber supervillain? Or just a harmless pyrotechnics expert entertainer you can hire to liven up your party?

Not even an OC. This is a character from the blindbag toys. Therefore she is canonical and (C) Hasbro. This also explains why she looks like a lazy Twilight Sparkle recolor - it's because she is!

Too cute not to draw, though, because adorable unicorns with bombs. D'AAWWWW!!!!!
