Aaron and Jessy have been dating a long time now. Like his best friend, Cedric with Raina, he is truely in love with Jessy, vowing to protect her from her suitors and help her out with her and her friends' cases. In certain stories, Aaron is very helpful to the team no matter what it is.
In "LMXB: First Case" he and his group want to do a case like their girlfriends do. So they form their own team called the LMXB. In JLMXB: Jungle Adventure, he forms a bond with Jonny Quest and when Jonny becomes part of the Junior LMXB, Aaron becomes his teacher.
Like Jessy with OogieJess, Aaron can turn into a monster by drinking a potion as well. BoogieTeen4 is like his archnemisis Oogie Boogie except with his hair, and hoodie and he's skinny unless he eats some people. As BoogieTeen4, he is charasmatic, charming, suave and hungry. He has a friendly rivalry with HarPI(his best friend Cedric) when it comes to crooning. BoogieTeen4 turns back into Aaron by two ways. 1) The potion wears off or 2) he kisses his true love, Jessy.
