A little weird but every piece of media that involves fighting infuriated me enough to learn how to kickbox. Let me explain.
I always felt a little self-conscious that I didn't know how to fight? I don't know why but eventually I got my Dad to teach me since that dude was like the third scariest street fighter in his town (the other two were my uncles).
But if I were to give a specific comic that just straight up motivated me, it was Tomorrow's Joe. It helped me be less self-conscious with my fighting and made me realize "Wow.... I really am doing good" (the only thing that's killing me is footwork, I seriously need to find time playing handball). The uppercut chapter hyped me up so much I was like "is it really THAT hard to do an uppercut????" and made me wonder if I could take the characters in the manga which is a weird statement considering the fact one of the characters was knocking out bulls but like... realistically speaking.
Another one was this webcomic book in High School I found that showcased different webcomics and I was like "You know what? I should make a webcomic" and my teacher was like "Yeah you should do that".
Not a comic, but Steven Universe motivated me into writing again since I didn't like the show as a kid for whatever reason (probably the way they handled villains... yeah it was most likely that). In High School (before I found the book in the Library) I was sorta comic'd out. Felt like that scene from the Godfather "THEY PULLED ME BACK IN!". Hell, Red Giantess was created IN RESPONSE to Steven Universe and that was way back in 2016 when it began as a Green Lantern/Booster Gold rip-off. Flash forward to 2023 and it became it's own beast (that still retains the themes of the original, just expanded from Hell and back).
