Oh ok, you meant my favorite character from my own story. I was about to characters from my favorite mangas.
Anyway, here's my favorite character I've made (so far)
He's the protagonist of my JoJo fan series I used to upload on amino. His name is Joss and he's a kid from a really small town in Germany. The idea of his character is that I wanted him to be a guy who struggles with keeping his anger in check and blows up at people when he's under stress. His stand reflected this, which an ability that shoots bullets in all directions at a rapid rate and it builds up stress from the damage it takes and can shoot single bullets with even more force. He also ends up learning the spin and gets his act 2. His stand's second act looks mostly the same, it's just sleeker and it can no longer shoot rapid fire bullets, only powerful spinning ones so he has to be more accurate with his shots. The spin was meant to represent learning control and discipline in order to calm down and think rationally in stressful situations, but it still has the power to blow up at people when it takes damage. In the end of the story, he drops his stand entirely and only uses the spin, showing that he now has matured and won't lose control of himself under stress.
He's my favorite because even though I never finished the story, I still got to do some stuff with him. I think it's really important to learn how to be mature about your feelings and let them out in a safe, controlled manner. I've had similar problems earlier in my life, I think I'm mostly over it now, so I put that part of myself into the character. It made me relate to him, love him, and write him in a better way than I could've otherwise.
I have new stories that I'm working on now, so I think I'll have characters that I like even more than him. I'm 6 months into a comic and working on starting a new novel, and already I love the characters I'm coming up with. Even then, Joss will still have a special place in my heart :3
