Back in my roblox days (im embarrassed to even bring them up.) I went by robinthegamerboi
And after a while I got bored of Roblox after thinking that I probably made a a few people uncomfortable on accident (I was 13-14 at the time)
As for the zelo part. I wanted to feel a bit more original aka I didn't like being called Robin anymore.
Then I decided to usually call myself a gremlin coz boredom hits me in the balls
So after a few thoughts. I combined them. And well. ZeloTheGremlin was born.
As for where I found Wario. I can't actually remember. I didn't fully do research till I saw a video of Warioware MOVE IT! came to my recommendation page.
