I never watched reboot...probably due in part to being born in the US? I had to go look it up.

The idea actually came about due to my roommate/best friend and I joking about how Axum was just a virus an then turned into like a little Shimeji like thing for Tech's computers and was his permanent recycle bin. He wants to get rid of a file permanently? Drag it over to Axum and let him tear it to shreds.At this point he was still kind of an adaptive VI and did whatever Tech told him to. And then her character Contra/Contraband gets attached to Axum and starts playing with him and he gains intelligence on emotion and such enough to mimic it. Tech reprograms his intelligence to full AI status, not realizing that Axum will become incredibly intelligent. Contra complains about having to go to Tech's room to visit Axum(cause even though her and Tech are total bros,he has a life that she doesn't want to interrupt just to visit her computer pet.

cue tech starting to prototype Axum's body.

First go is a small inconspicuous thing mostly suited to recon.Tech scraps it due to malfunctioning hardware when he uploads Axum.

Second go is bigger, upon a suggestion from his boyfriend/co-leader of the resistance. This one functions better but is still buggy and unarmed.

Final prototype leaves Axum with a body that is just about bullet proof, and has a kinetic type shield generator. He is big enough for an entire team(about five people) to ride and is equipped with both tazer-like claws and a laser rifle in his mouth.
