An autonomous, spherical, electrically charged weapon created by the combine but some how it's a humanoid!? Ahem well...good luck getting zap by that thing...

A lot of crazy things that the combines are experimenting on lately...but this one is very different, Electra likes to play pranks of passing civilian vehicles and annoy other over watch unit when she's bored, and sometimes she throw those sphere rollermines on the cliff just to see them explode when they hit the water...
