Character: Clay Terran from Phoenix Wright: Ace Attorney - Dual Destinies
Haven't seen this installment of the series, but everything I know about this character's personality, interests, and design feels very Leon to me.
Closest picture I could find of Leon for reference (Not his normal outfit):
Character: Ron DeLite from Phoenix Wright: Ace Attorney - Trials and Tribulations
As far as I'm concerned, Ron and Angelo might as well be the same character. Same hair, same personality, same premise of "wet noodle of a guy who somehow wound up doing crime." This isn't even really a spoiler for Ron despite the series he comes from. It's one of the first things you learn about the man. Absolutely hilarious.
Angelo for reference.
I forgot which anime this screenshot is from. I wanna say Urusei Yatsura?
I feel like if I really leaned into this type of style, Emil would basically look like a color-swapped version of the character above.
