Rapidmon (Ultimate)

Rapidmon is a Cyborg-type Digimon, the Ultimate form of Terriermon. Called "The Keen Hound", he defeats his enemies reliably with speeds close to the speed of light. Alternatively, Rapidmon (or GoldRapidmon) is the Golden Armor form of Terriermon using the Digi-Egg of Destiny.

Rapidmon Armor
Rapidmon Armor never fails to stop his prey with his homing missiles. Led by fate, this holy knight travels at the speed of sound. When he gets in alignment, his cannons shine. Hidden within his holy golden armor lies a great strength.

Abilities
His huge ear-type radar can act even in the darkness and can even discover enemies that are far away.
