Colin is a character from the anime Level E, where he serves as a member of the Dogura Kingdom's Royal Guard. He is a young adult male with brown hair cut to ear length and black eyes. He has been in service as a guard for only one year, making him the most junior member of the team assigned to protect the planet's unpredictable prince.

In terms of personality, Colin is portrayed as the most sensible and good-natured individual among the Dogura people who appear in the story. Unlike his more experienced and wary colleagues, Colin has not yet been fully exposed to the prince's long history of troublesome behavior, a fact that leaves him less cautious in his duties. He is characterized by a tendency to trust people openly and believe things in a straightforward manner without harboring suspicion. This trusting and honest nature stands out against the more jaded attitudes of his fellow guards. A personality assessment places him within the ISFJ type, often referred to as the Defender, which aligns with his loyal and dutiful yet gentle disposition.

Colin's primary role in the narrative is as a supporting member of the prince's entourage on Earth. He is one of the subordinates who must follow and manage the eccentric and troublesome prince, often being dragged into elaborate schemes and pranks. While his superior officers, Captain Kraft and the more analytical Sade, are frequently exasperated by the prince, Colin's shorter service history means he is less wary and therefore more vulnerable to being manipulated or caught off guard by the prince's antics. His function within the group is to contrast with the others, providing a perspective of relative naivety and normalcy.

Information regarding Colin's specific personal motivations, notable abilities, character development over the course of the series, and details on his key relationships beyond his professional association with the prince, Kraft, and Sade is not available.
