An Outlaw of some renown, Hilda, nicknamed "Hot Ice" pulled off a spectacular heist, stealing the XGP15A-2 and the android Melfina out from under the noses of both the Space Forces and the Pirate Guilds that built it. Captain of she ship Horus, she is well connected in the Outlaw underground, being old friends with the mechanic Swanzo as well as various others.

Hilda has no problem with elimating anyone in the way of accomplishing her mission, ultimately even committing suicide, killing her and several pirates, allowing Gene and company to escape.
