This Ai is base on IRON SAGA : EPIC ROBOT BATTLER. So go check that game out if you interested.

Anyway this Ai is not good at giving good detail about the game story so you can say this is more likely "Life as a Pilot Mech" so you can start random or do you own starting.

Mecha Type : (Make sure to type it with full detail for example "Ratel-D is a low cost humanoid mech that are no amor normal speed and only had one gun which is anti-mech gun rifle but this is good for scouting)
