Thinking about how traumatized the Hagure Leaguers probably are...
Note: I mention Narcissistic personality disorder in the last segment. I do not have it, nor know if anyone I know has it, so I wrote my understanding of it. If it is wrong, please tell me.
Gold Arm is likely in constant fear of forgetting what he knows. Dark clearly has messed with his memories; They made him forget Silver Frontier.
Gold Foot hurt Gold Mask during the arc; He likely fears hurting his family again.
Gold Mask saw first hand what happens to the soldiers, they're likely terrified of losing their family again.
Gebara is traumatized by being abandoned, and likely worried about being manipulated again
Wild Hawk is a difficult case, as he was mostly a Stray due to hubris, but he was unable to find work. The way his eyes light up when he's told people want to hire him again should tell you something.
Deus and the rest of his team desire nothing but to be defeated in a game, knowing they are "useless" and "defective". Dark has ruined their self esteem, and they are so desperate to prove themselves, but as soon as they lose their flight, they feel helpless.
Dyson is one of the most obvious cases of trauma; He fears everyone has come to dispose of him, his former employer instilling in him the worst paranoia ever. This man thinks children are out to get him.
Sisley is a little different, as we have no clue to what he did before becoming a pirate, but he obviously is very distrustful of Dark. It's possible that he is not directly traumatized, but lashes out on behalf of his crew, which is a bunch of Leaguers abandoned by Dark.
The Earth Pulse Miners were easily manipulated, but they are seemingly young, and have not let life beat them down. Despite being abandoned and manipulated, they still trust easily. They are probably a little scared of being manipulated again, but they know that they can trust Windy.
Alucard is probably simply lost in life, no longer having the sole purpose of bringing oil back to his master, and struggles to understand society.
Jet Setter is an example of how trauma can make people into their worst selves. He saw his team killed, almost died himself, and his response was to start taking Leaguers that were already meant to be scrapped, and make them fight for his entertainment. Those who did well would be scrapped later. He never once thought about how easily he could have been sent to that arena, outnumbered and overwhelmed, and literally crushed. While he did destroy the facility and free those that still lived, he is likely going to need a while before he stops trying to hurt people.
Amp is traumatized by her own sister turning against her, but she is likely more concerned about losing Watt again than whatever Watt might do to her. She turned to police work to try to help everyone she could.
Watt learned life was unfair, and took it into her own hands, not thinking about her sister at all. She probably fears hurting her sister again.
Thirteen is SO traumatized. First off, he's always been alone, it's only natural as an Iron Golfer, as golf has no teams or teamwork. It's everyone for themself. So he has never had reason to trust anyone, and never worked with anyone long. Secondly, he is a hitman. He turned to literal murder as a job opportunity. And he was efficient. When Juurouta stopped his attempts, he nearly pleaded for another chance, so desperate to prove himself useful. He wants, needs, to be useful, because otherwise he is alone in the world. I recently read a bit about Narcissistic Personality Disorder, and how it can come around from never having the affection and praise of others, so the person has to hype themselves up, and end up having to do it so much they end up seeming obsessed with themselves. Thirteen was so confident in himself, and likely had NPD or was on the path to developing it in himself. We can see how he starts to crumble as soon as things don't go like he calculated, and he starts to doubt himself. As soon as he knows he has lost, he says "I lost... You can dispose of me as you see fit." Thirteen sees himself as useless at this point; he has failed and therefore is no use to anyone. He has fully accepted that he is going to die, and he is so shocked to learn he will not be killed. His entire world is shattered by the revelation that failure is okay. And then he is once again left alone by Magnum. Like, Magnum just walks away. It's kind of surprising Thirteen didn't just kill himself after that.
I like them as homies, and their dynamic is really nice! But I think of them more as platonic than romantic. I think the ship stuff is cute, but it's not my thing.
BABIES!! Like Wheeljack and Bulkhead, I see them more as really strong friends instead of romantic interests. I really like seeing them together though, because they're very cute! Let them play basketball together! There was that one scene in the show that really made me happy for Gebara, which I won't spoil, but anyone would know what I'm talking about if they've seen it.
