Who's your favorite character(s)? Whose character arc is your favorite?

(I wanted to add something since there are not many conversations or topics.)

personal answer (I do not hate any character, unless it's the intention ex: a 'villain'):
Jaime Reyes/Blue Beetle: This mainly stems from nostalgia from watching his Batman The Brave and The Bold version and back then I knew nothing about Blue Beetle. I loved seeing his YJ counterpart especially with his situation with the Scarab from the various mini conversations to seeing him become more confident in wielding it.
Bart Allen/Impulse, now Kid Flash: There almost no reason to dislike a friendly, humorous, hyper-energetic speedster. He finds everything in the relative present amazing. There's also his 'original' personality while in his original timeline I feel adds a hidden maturity/layer to his character. He's often seen as jovial and happy, but he's also come to appreciate his current present as it has what his past doesn't.
