I can imagine many more such as
- Optimus Prime (A wise sounding A.I reminding you not to do anything too crazy at times)
With a look of a wise futuristic monk
- Grim Reaper (Part of the oldest reaper team member maybe the 1st? having transferred him into A.I form)
With a kind of spawn look and futuristic too!
- The twins (when 1 A.I is not enough there is 2 sometimes they agree and sometimes they don't)
One blue and one red with animal traits like ears
- A cyborg (Part of the police division specially created for Mek Pilots)
Looks armored and metallic.
