Shameless Fox is one of the three Jaegers featured in Pacific Rim: Training Day.
After Wolf Queen runs out of ammunition, Shameless Fox engages Crabcat in combat. Initially, it has difficulty, but thanks to the Lieutenant Commander's advice, Jesse and Dodger are able to gain the upper hand. Shameless Fox then brings out its extendable sword and plunges it into Crabcat's chest, killing it.
Shameless Fox possesses an extendable sword capable of piercing the hide of a wounded Kaiju.
