One of two dragons designated to awaken Taven & Daegon in the konquest mode of Mortal Kombat: Armageddon. Caro was assigned to Daegon. Caro somehow lost telepathic contact with Blaze shortly after the two brothers were entombed. Mistaking this for the signal from the fire elemental, Caro awakened Daegon prematurely.
Upon awakening, Daegon enslaved Caro, using him as the basis for the Red Dragon clan. Daegon used Caro's ability to create portals to transport his troops between realms. Daegon also used Caro's DNA to create a race of half-human dragon hybrids.
Caro was eventually freed from his servitude by Taven, and despite his weakened state, took his revenge on Daegon by destroying his precious Red Dragon clan and headquarters. His final fate is unknown, however, in Taven's ending, Quan Chi is said to have killed Caro.
