"An old soldier who's served the Frieza Force since King Cold was in power. He uses his well-honed techniques to train the younger soldiers."
Caluppa is an elderly green-skinned member of Dodoria's race who wears Battle Armor similar to Zarbon's. Due to his green skin he can be easily mistaken for a Namekian but lacks their pointy ears and has a spiky head common among members of his race.
Little is known of Caluppa's history but presumably like most fighters in the Timespace Tournament he is a member of the Frieza Force from one of the many timelines connected to the Timespace Rift created by Tekka and Pinich's wish to Shenron.
Caluppa is old veteran of the Frieza Force who's served within the organization since before King Cold handed over control to his sons. He uses his well-honed techniques to train many of the younger soldiers within the Frieza Force and claims to Tekka that he has trained at least 8000 soldiers over the course of his career. Interestingly, unlike most Frieza Force members, Caluppa is a master swordsman.
After learning how to recruit new allies from Master Roshi, Tekka's Team can find him fighting alongside Dodoria, Zarbon, and several other Frieza Force members. They can recruit him by KO'ing him with a Zenkai Attack. After he is recruited, he will join Tekka's team (allowing he to be selected as playable character) and will appear in the Team's Spaceship.
