I'm sorry, but what exactly do you copy from Yuri? His coolness? His bantz? His vigilante arc?
In my view, a character like Yuri is best executed when he's a foil to the other surrounding cast around him. Flyn, Judith, Estelle, etc are what makes Yuri's character compelling with how they bounce off each other, and imo, that's why I didn't have an especially high fondness of Yuri once it came to the latter part of his arc, because once it became about that one specific trait of his, he's far less compelling a character.
My go-to of a protagonist that more games should look to copy the formula of would be Luke's arc.
