»OddxAelita
The popularity (or lack thereof) of non-canon couples aside, Odd and Aelita are probably the most widely accepted one out there. Though it could just be in his personality, Odd has been known to like to flirt with Aelita a little bit... This is especially apparent in season two. His nickname for her, "Princess," is also very widely thought to be a hint at his feelings for her.
Fanfiction often puts Aelita and Odd together when Jeremie and Aelita have just broken up and she's in need of some comfort... Go figure.
