OK I’ll give info on my third RHG named Warmonger:
Warmonger is a robot that is made of Antarctic vibranium which is also known as anti metal which eminates vibrations which cause the atomic molecular bonds in metals to weaken and in most cases liquify. Warmonger is also designed to be an anti-Punisher (A Punisher being a disposable robot soldier designed to defend the city in case my RHGs go rogue) in case the Punishers get hacked.
