Prep-ella

Prep-ella is a half-girl, half-aeroplane. With her propeller tails, she spins them around when she wants to fly. Her wings also allow her to fly about.
Prep-ella is not unlike Superman; flying around seeking out danger. When she finds danger, she uses wind gusts from her wings and propellers to knock over the 'bad guys'. She can also use her propeller tails to 'whip' them.
