Ok, because I am making an indie soldier, and in his biography he receives a set of dog tags at the end with his code name on it, god, six chapters of just... Pure.... Awesome! Maybe a lot of gore because he is under training from a secret assassin group, he shall be amazing! and this is just when he is seven lmao!
I would recommend you focus less on making someone who was a "super badass assassin" at age 7, because that concept looks like it's going to be rife with cliches, and focus more on fleshing out his story so that it looks like you're creating a real character with real feelings and emotions. Secondly, just under this thread you're asking questions about Yoda's species, and on top of that you already have two characters.
You're falling into the trap most of us have in the past: making a lot of characters and ending up not doing anything with them. Slow down and reevaluate what you're doing.
The Yoda idea was thrown out, the assassin has replaced him, my final count will be three characters for now and once I either retire one or they are killed I might make another character.
