Don't even spoil any episodes past Aliver I haven't seen any of them yet omg! And Allegro doesn't really bother me tbh. I actually think he's kind of funny and creepy. But when I found out he was returning in Largo I was actually pretty shocked. I didn't think we were going to see any more of him! But I'm interested tbh, I rlly want to see Largo. I just need an air date for the last 4 episodes on the wiki tbh.
Well, Basically, what I did is First, drew the characters in adobe illustrator, basically tracing the bases from scenes from some episodes and some of them, I drew myself. Second, I swapped the colors of their clothes, and eyes, and put their names in the same colors, and third, I made a colored bkg for each one.
