I was thinking, you do a LOT of U6 headcanons, could you do U3 headcanonS this time??//
I don't have as much to go off of for Universe 3, but I'll give it a go!
The robots of Universe 3 are either natural beings with metal-like skin (similar to U6's Metal Man) or beings given robotic forms, such as body modifications or empty hosts for souls. Ghosts are rather prevalent in U3 and are often put in these shells either against their will or by personal choice in their final will and testament; it's like donating your body to science but, instead, it's your soul.
It took a lot of arguing over semantics for some of the robots to be allowed in the Tournament and not considered illegal tools being used by Paparoni. Ultimately, it came down to the Zenos as the deciding vote and they let them stay because they seemed fun.
In fact, robot rights are widely debated in some reaches of U3.
Some of the other robots in the Tournament were offered modifications with fusion capabilities, mainly as a contingency plan if a component of Anilaza were to go down. There are multiple alternate Anilazas that have yet to be seen... or even been proven to work.
Mule is one of the weaker Gods of Destruction. Part of his reasons for building his Mosco suit are to offer him more durability and make him seem more imposing to his subjects.
Mosco's communication in beeping is a form of Morse-like secret code only shared between him and Campari.
Ea constantly has to be kept in check because he keep making promises he can't keep and his mouth writes checks his ass can't cash. There have been moments of intervention from Mule and Campari.
And for a silly one, with my favorite Universe 3 character... Katopesla, in addition to his work defending justice, is also a major brand figure. He does soda commercials.
