Heres a drawing of a robot girl mini sentry i came up with. Her name's Mimi.

She's a sadist (Enjoys seeing others in pain), Going purely off of how much mini sentries annoy other players.
She often can be found doing her own thing and doesn't tend to stick around her engineer for long. (Going off of how much mini sentries liberate you to be less dependent on your sentries)
