Sam Carter from Stargate SG1 would be an amazing resource for the NCIS team when it comes to any sort of technological mystery. The NCIS agents might be in awe of her intelligence and ability to understand and work with advanced alien technology. However, she might find the more down - to - earth, crime - focused investigations of NCIS a bit of a novelty at first. The interactions between these characters from two very different universes would be full of humor, tension, and mutual respect as they learn from each other.
The characters would interact in very interesting ways. For instance, Jack O'Neill from Stargate SG1 is a military man with a sarcastic sense of humor. He would probably find Gibbs from NCIS to be a kindred spirit in terms of military discipline, but their leadership styles might clash at times. Gibbs is more about leading by example and getting his hands dirty in investigations, while O'Neill has to deal with leading a team on dangerous off - world missions.
