Sebastian is easy going and sometimes gullible, often falling for Iris bluffing or making excuses to conceal her powers. He's also artistic as he is an expert in graffiti, sometimes being seen tagging a monorail or the side of a building.

Iris Tyler:
In The Ultra Violets: Power to the Purple, Sebastian has a quite fondness with Iris, usually bonding with her about art and the environment. Sebastian also shows to genuinely care for her despite Iris lying and making excuses as an attempt to hide her powers, thinking Iris as a "mysterious but interesting" person. Even helping Iris to round up the brain washed students as Iris told him it was for a "public art installment".
