Random Thoughts.....What Are You Thinking?

Name (full name and how they prefer to be called)
Age
Physical description (including smaller stuff like eye colour, hair style, etc)
Personality
Clothes (or preferred style of clothes if you want them to change outfit often)
Whether or not they pilot a mobile suit / mobile armour
Pilot suit / normalsuit (spacesuit) design
Occupation (junk dealer, mechanic, referee, commentator, groupie, etc.)
Sexual orientation (only if you want them to have a romantic interest involved)


If they pilot a mobile weapon, give a description of their mobile suit/armour (anything from any Gundam universe is cool, but the more powerful it is, the more expensive it is; GN Drives take years to make and require travelling to Jupiter and back, so they're going to be a shitload more expensive than a Deuterion Battery made in China for example, and this will affect when your character appears).
Also design or give a description of their personal emblem (will be displayed somewhere on the mobile weapon).

Using pre-existing suits as bases or examples for appearance is fine, as is using actual parts right off the suits or even the entire suit themselves. Also specify their weapons loadout, the pilots' preferred combat style, if they fight as part of a team and how they travel between arenas/tournaments (via mobile weapon, truck, cargo ship, warship, public transport, etc. (again keep in mind cost)).

If they're part of a team, feel free to go into as much detail about the team, their mobile weapons, and their tactics as you want. If you want a team but can't be bothered to make one, I'll make one based around your character's mobile weapon and combat style.
