Owen Reynolds is Mike's eccentric best friend and the ideologist of the series. He is one of the three main ninjas. He also describes himself as "cool hat guy" in Season 2.
Owen isn't just in the Supah Ninjas for comic relief: he has quite a few tricks up his sleeves. He has a sense of humor that he's used in many types of situations as well. But still, he is always there for Mike, and other people like Amanda. He can sometimes be a bit over-confident, but is a supportive friend with tons of courage.
Best Friend/Partner In Crime/Classmate
Mike and Owen are life-long childhood friends. Owen knows a lot of embarrassing secrets about him and they usually goof off together while fighting crime as seen in Pilot. Throughout both seasons their friendship seems to grow stronger and they tend to be more reliant on one another depending on missions and types of assignments.
Longtime Crush (Season 1)
Owen has had a long term interest in Amanda's best friend Kelly since the first episode. Much to her chagrin, he enjoys his corny pick up lines and flirts with her, not seeming to take no for an answer. He has a dream about her in DJ Elephant Head and they kiss however it's only a dream.
Owen befriended James while Mike had broken his leg from the previous summer. He mysteriously disappears after that summer. James had become a criminal in "Subsiders". Owen tries to get him to leave the group but James says he will stay with the gang until it feels right to return to his family.
Owen seems to have a good interest in Martin even though most of the time he doesn't treat him the same way. Owen always tries to talk him into doing certain things even if he feels uneasy about it. Their relationship can be best described as a love-hate relationship.
Close Friend/Partner in Crime/Classmate
Owen and Amanda are close friends throughout the series. They both tend to joke around together and make fun of one other at times. Amanda briefly believes that Owen likes her which causes drama in the group since Owen knows Mike likes her. Connor spread this rumor to her. Mike thinks they like each other but Owen says he doesn't like her in that type of way and wouldn't do that to his best friend since Mike likes her.
Good Friend/Helper in crime
In "Kid Q", Owen is paired with Quinton for a science fair project. After the ninjas defeat Wesley, Owen becomes friends with Quinton. When the Ishina destroy the dojo, Owen along with Mike and Amanda bring in Quentin and expose their true identities to him. While fixing the dojo, Quentin accidentally lets Two Ton Harley out of prison. After the ninjas defeat him, Owen apologizes to Quentin along with Mike and Amanda and invite him to be apart of their team.
In some episodes of Season 2, it's shown that Owen had a crush on Paloma Peru, the school news reporter who he finds cute. They began dating in "Wallflower" and grow closer together in "M@yhem". Mike and Amanda thought Owen dating Paloma was a problem because she was investigating the ninjas identity but in the end, they apologize to Owen about Paloma when she states that the ninja's identities should stay a secret.
Best Friend/Training Instructor/Fighting Robot
When Owen first meets Yamato they become fast friends. Owen usually calls him tin man as a nickname seen in Pilot. They both tend to joke around with each other during training sessions too.
