Unicorn

After the Heroes defeated the Sky Pirates on Earth and had secured the majority of the Sweetypies there, Unicorn made his appearance above Pure Heart Valley, intent on destroying the world. Mao Mao's team of Heroes and the Sweetypies returned home via a warp gate to see the Chaos Bringer unleash a wave of destruction upon the great cities of their world. The Sweetypies joined together to form the Matrix Cannon, the Vanguard Booster and the Nemesis Shield for the Heroes to use against Unicorn. The Heroes flew into Unicorn's maw and blasted their way into his energy core, damaging it enough to send Unicorn spiralling out of control and destroying him.
