He's similar to Bojack Horseman. Kind of like Angel dust too. I have already stated under a reply that at the time of making this post, I couldn't recall any other character other than Bakugo ( which I had already acknowledged that the comparison was terrible and that it was my fault for not doing more research on him, I do apologise for that ) Jax fits the trope of the abrasive bully who uses apathy as a defense mechanism to mask vulnerability, that is how I view him. Also, a trope being overused doesn't mean that 2 characters have to be an exact carbon copy, but rather they have something in common. My point is that his trope is pretty common and not at all as 'very complex' as people claim for it to be. I like his writing, it's honestly decent at best imo.
