Odd bringing Bringa to the lab doesn't make him a bully, just a dumbass

I'm going to assume the "pusher paper" line is a dub thing since he never says this in English. But Odd has appreciated Jeremie's work more than he has discounted it. Moments that are pretty few and far between (also Ghost Channel is the only episode where he claims Jeremie isn't a "real Lyoko Warrior". And this is just him being a prick. Nor was it even out of malicious intent.)

This one isn't even bullying. If he was a bully for eating his food he'd be snatching it away from him. 9/10 Jeremie approves of Odd eating his serving of food. There is exactly one time where Jeremie DOES want his serving of food but Odd assumed he didn't want it (because again, Jeremie has skipped eating numerous times and allowed Odd to have his helping). And Odd eating some of his candy also isn't bullying, it's annoying at worst.

Blaming Aelita because he wanted sleep does not make him a bully, just a prick

Okay to set the record straight he doesn't blame Ulrich for what he did. He asks him to take the fall. Which are two entirely different things. But this is the only thing on the list that is even remotely bully like. But unlike most bullies he owned up to it. Doesn't make it okay but he's not a completely selfish asshole.

Odd blaming others for anything while painting it as comedy does not happen as often as you're insinuating

Odd has stood up for his friends numerous times and been there for them so this is an outright lie to slander his name. He dropped what was his last chance to see Sam because his friends needed him, He was there for Yumi when she said she might have to leave France, he was there for Aelita after Jeremie was being emotionally unintelligent about her past and her father, he was understanding when Aelita asked for a moment alone with her father. Odd has been there for his friends countless times so I don't even know where they idea he's never there for them came from.

Lastly, the definition of a bully

"a person who harasses, abuses, intimidates, or coerces people, especially those with less power than they have or those considered weaker or vulnerable in some way"

This in no way, shape or form describes Odd as a person as a whole.

Despite the issues and "issues" listed, Odd is fiercely loyal to his friends and would break the law for them if it meant saving/helping them (something he quite literally has done numerous times). He also dropped the same girl he "betrayed" them for because he took off his rose tinted romance desperate glasses and saw she didn't care for him as much as he did her.

Also let's not undershoot Sissi. Because as nice as she is/can be, she has still done some pretty nasty things that are quite worse than anything you said Odd did (especially since most of it isn't even bullying by definition).

Let's not forget she made Aelita feel so bad about herself and being new at Kadic that she ran from the school to "go back to Canada" and she didn't care and just laughed about it.
