My favorite character from anything is Ai-Ai from the Monkey ball series. Ai-Ai has his happy-go-lucky persona. A close second is Sheldon (preferably young Sheldon) from the Big-Bang theory/Young Sheldon. He is soooooo funny........ Like when he goes to penny's door, knocks 3 times, says penny every time, and she answers with an annoyance in her tone, That gets me rolling around on the floor laughing.
