Archimedes has all the appearance of a praying mantis of humanoid proportions. He carries himself on four thin, insectoid legs attached to his thorax, with long abdomen behind, and bears two pairs of wings on this part of his body. The outer pair forms a hard shell to protect the fragile inner pair. He can fly with these wings, but with little to no grace or agility. His torso is perpendicular to his lower body and is of more humanoid proportions rather than the thin prothorax of a true mantid. His arms end in long, serrated, scythe-like blades, while a long, stiff neck holds his wedge-shaped head above his shoulders. His eyes are huge and ovoid, unlike a true mantid's in that they possess true pupils with all the focusing ability of human eyes. He has two long antennae and powerful mandibles that prevent him from speaking any but insectoid tongues. His entire body is covered with thick, green-brown carapace.

To modify his form, the mantis has a respectable bit of cyborware to call his own. Cyborware hands have been grafted to his forearms at the 'wrist' joint of the scythes, usable when he folds his scythes to his forearms and holds them closed that way. An entire second set of small arms are also joined to what passes as his lower ribcage. Though not visible, he has several memory chips augmented to his brain for the storage of all manner of robotics facts and diagrams.

Archimedes is a brilliant man, wholeheartedly and enthusiastically devoted to his work. He is a fellow of good cheer as well, always ready to take an order and get right to work building his next robot. He'll work with or for absolutely anyone as long as he is treated with respect, though he responds much better to similarly friendly and well-meaning people. That being said, he never forgives or forgets a slight, so one had better be on their best behavior if they want him to customize a 'bot for them.
