Any aesthetic is fine (such as metallic), but they're generally very human with an unnatural "doll-like" appearance. So sprite wise they'd typically be pale/look a little off, but there isn't any particular requirement here as a synthetic is just an artificial body that's enhanced and linked in to the network of an Entity. Anything from YohRa to a straight up cyborg is good.

Skill-tree will be something like:

Anti-Magic Field, toggle-buff: +5% DR, light passive AoE damage.
Suppression: Skillshot/stronger variant of the gem.
Self-Repair: Cleanse/heal.
Eradication: Aura. +10% AP / +5% DR.

Might give them access to all three gems but increase opener costs by 5, something gimmicky... Still brainstorming here.
