Unicorn is a pink unicorn with the ability to fly. She is the only Animal Mechanical who cannot walk on two legs. The horn on her head can be made to blink like a beacon, allowing other creatures to follow her while she is flying. When flying, her legs are bent backwards and her hooves become rocket boosters, propelling her through the air. Her wings are folded inside her back, except when in use where they provide direction and speed control. Unicorn can also throw lightning, and create a whirlwind with her horn. She is also Rex's love interest.
Like Pinkie Pie,Unicorn possesses the element of laughter.
