Hello there! Thank you so much!! : D
Lets see here...
Catman was originally created to be a pet but he actually acts as vermin control
Wolfman acts as a guard to his robot creator
Spywomen overalls security cameras and aids the police
Plagueman works in medical care and creates viruses/vaccinations
Balloonman is suppose to spread happiness and joy, and make people feel better in general but he was accidentally built a bit too big with a smile too large so he just sort of has a sad existence instead
Dragonman is a play/circus robot and his purpose is purely for shows
Tremorman helps with construction by making tremors in the ground, he's also really good at digging!
Marineman is a deep sea exploration robot
Fossilman is a museum guide as well as a mascot for the museum he works for
I think that wraps all the ones I currently have reff'd up, thank you so much for the question! I don't really have weapons and whatnot planned out because I focus on the designs and stories more
