But like, unless they wind up being important to the series later, there's no point other than for you to have free access to my world--and maybe whip up some kind of spin-off.
Gotta be honest, that don't sit too well with me. Especially since everyone involved in the series up to this point (which is already 90% complete,) had to bring something to the table. To me this question is like asking if you can live in my house without paying rent or doing any kind of chores or anything.
That makes sense. Unless they could become important later (which is something I think we both know the answer to), I guess I'll resort to just making them in my own universe... it might be more informative if I explained the character overview idea that I had so far to you, though, if you don't mind.
So basically, there'd be this teenager (leaning towards a hedgehog, but don't wanna be generic) who basically lives a double life. His parents are more education-heavy, and they just want him to live a steady life with a family and settle down like a normal person. This unnamed kid, though? He wants a lucrative life, he wants adventure. And he wants to join the Blitz Pit. He's been doing some training by himself, but when he actually has to confront some baddies, he gets hi butt kicked, and a trained fight at The Blitz Pit sees this and decides to train him. Thus, this teenager would be living half slice-of-life and half-action-packed adventure.
imean it's not a bad idea by any means, just it doesn't have to be the Blitz Pit. Or a fighting arena. It could be something else entirely that would require some level of fighting experience.
for example what if he's inspired by (Sonic Heroes styled) teams of crime-fighters and wants in on that action, but gets beat down when he tries on his own. Let's say the guy who sees and trains him used to have his own team, but they split for unknown reasons that could be revealed at a later date?
You don't have to go with that idea but that's just an example of how you can go about it--plus give the trainer some depth too.
