I think Pepe may be my favourite character on Discovery.
In all seriousness I have found many interesting and flavourful people to RP with, of all shapes and sizes and different RP styles. Many I have enjoyed but to play favourites would be unfair on many. As long as you can show that your character is not just you RPing yourself, then you've done most of the work in creating a believable character.
Pepe ironically, Chanteloup unironically. Not that I know many characters but goddamn, even with my reputation of Gallia-hater I really have to love the Amiral.
