Blue Mauli

Mech Designation # H2SO4 B-F

Mauli may look ridiculously scary with her extra set of arms and
quadruple, double-edged tempered protosteel pickaxes, but she's a 
sweetheart underneath that carbonox armor. trained as a highly efficient
excavation specialist, she hammers away at bedrock with twice the speed 
of a normal two-armed miner. she carries this over to her new derby 
position, using the extra set of shoulders and elbows to inflict twice 
the blocking pain.

on the track, her pickaxes combine to form a massive throwing star that
can be hurled like a boomerang, or used as a shield to block incoming 
ballistic attacks. her mask of speed lets her keep up with the rest of
the pack, given that her extra arms take the place of where the usual
booster wings would be.
