Bunnie was finished years ago, awaiting other rebel buddies.

Rabbot was amputated and prepped but was rescued before implants were installed, so she gets around in an exo-suit. Amy one of the few pristine ones, armed with a power hammer. Both Rab's suit and Amy's hammer cobbled together from Eggbot parts, hence the red.

Cream's got a prototype neural implant that controls a polymorphic alloy, shaped by her mind into a friend named Cheese.

If Cheese is a character, then by technicality this is a round number of 4.

And that's it, that wraps up this little designing misadventure. Want to work on other projects.
