Rival Needed

Alrighty so; with the work being put in to get Seiken's second power installed- and so much emotional progression with Emily, I'm after someone to give Seiken the next push in his actual development when it comes to tackling his other emotional issues. Seiken has a severe issue with holding back despite his natural talent and skill in anything physical (with a few exceptions). He refuses to ever actually go all-out, he refuses to have passion, for anything out of fear of it biting him in the ass.

Before Emily, he never would have even tried. But she's opened the door to (with enough of a push) getting him to care about something. Specifically, there are a few different ways I'd like for this to pan out, and due to the specific requirements, I've made a wanted add up for it.

Passion for Basketball: I'd love to see him develop a passion for basketball again- when I wrote him out, basketball was one of the sports that Seiken was able to bond with Hai over. It has immense emotional meaning to him, and it's the sport he has the most experience and talent in due to his height (superhuman body aside). So re-awakening that passion could be neat- as well as make the Thunderbirds a more active "club".

• Teammate Rival or Rival: Someone to join the Thunderbirds as a friendly rival that's not afraid to call him out on his bullshit. Maybe the polar opposite of him, no natural talent, and got where they are through nothing but stubborn willpower and effort to hone themselves. Seeing someone that obviously just casually tosses that talent away out of fear of being hurt when he cares, could likely rub them the wrong way immensely. It could lead to frenemy, or rivalry depending on the characters personality. Having this person have a similar powerset that allows them to clash with Seiken when he's serious, would be fantastic as well.

Passion for Martial Arts: Something Seiken was immensely pleased with, it was the first thing hai taught him "to control his body" so that he felt like he had some measure of control that made him more than just a beast. The guy knows more martial arts skills than he does anything else really, but he refuses to use them. Thinking that he lost the privilege to use them after he used them to kill his own master (even if it was accidental).

• Teacher: Someone that could become a "teacher" for him again, maybe not in the way of learning martial arts (though he would need to shake the rust off), but in the idea of helping him understand himself, and his fear of them. Maybe opening doors for him in the field that he could do, since at the moment- he has no dreams, goals, desires, or passions since he thinks he's just a weapon, a killer, or a monster that has no real future in the modern world.
• Rival or Friend: Same as the Teammate/Rival thing for Basketball really! Just different material for them to bond over and such.

Open to new characters, or characters that are already made. No preferences on personality really, long as they vaguely could fit in I'm open to poking around the ideas and giving it a shot. :D
