No worries.
This is a personal matter, because you are the character's creator so you make the decisions. Personally, I like it when villains have a change of heart and become heroes or at least rivals/anti-heros like Shadow and Dr. Eggman.
My recommendation is for him to be redeemed and become a hero because, after all, he started out as a hero.He is also an anthropomorphic character, so it fits with the Sonic universe/lore.
Yes I believe. If he has a change of consience due to an unpredictable event of a decision he has to make. This decision will have to be based on his past. For example, like Shadow deciding to save the world because of a promise of a loved one.
What if Ominous somehow saw his mistakes because he encounters a person with a similar background/problems?
You were right. I'm from the good old days of 2010.
Juely is next.
Ominous seems like an interesting character at first but I found his background cliche and melodramatic. I did not buy that Ominous does what he does because he was scarred from a bullying incident. Also, I feel like bullying doesn't fit in the Sonic franchise generally. Furthermore, I found it odd that he was bullied at school 10,000 years ago.
Therefore, I can not empathize with him and cannot really understand his motives. The concept of misunderstanding is a nice touch. Maybe you could build on that as his motive for revenge.
His character, abilities and appereance are all clear. Just try to avoid repeating yourself. I found that you kept mentioning him self-loathing several times.
I also found the song and lyrics surprisingly good. Well done.
Overall, the page is well written. I would suggest you do not repeat yourself, as I mentioned earlier, and avoid writing in the past tense. Use only the present tense. It's the correct way. I believe if you replaced the bullying incident with something more relevant to his misunderstanding, he would be a more well-rounded character. Maybe if he was falsely accused of something?
Can someone delete my page "Ugandan Knuckles (2018 game)"?
