Cerberus

The Two Headed Dragon is a dragon-like creature that appears in the episode Map of Infinity where it attacked Ben's team for entering a room that lead them closer to the Map of Infinity. It resided on planet Mykdl'dy and guarded a piece of the Map of Infinity.

Appearance
A large maroon dragon-like alien with two heads. It walks on four legs and each head has six eyes. It also has very sharp teeth.

Powers
Its head on the right can shoot blasts of fire while its head on the left is able to fire freezing rays of ice. It has incredibly sharp teeth and neither power is capable of penetrating the stone temple it was living in because of its high temperature resistance. It's ice abilities are proven to be very strong as well as its fire, after Kevin had gotten thrown back from its attack.

Trivia

 * It's assumed that its home-planet is Mykdl'dy because the right side of Mykdl'dy is covered in fiery hot temperatures while the left side is covered in freezing temperatures, making it have a similar adaption to this planet due to its powers.
 * It resembles the Two-headed Snake from Vilgax Attacks.
