Questions about the comic strip Robotman

[scratch1300]

I'm an occasional reader of Robotman (alas, it's one of those strips that used to be better) and I missed some important developments. At first, Robotman was presented as a mechanical voyager from space who hung around with a sunglasses-wearing teen named Gary. Later he was seen with a kid with prescription glasses called Kevin. Now, he is friends with Monty and some fat guy in a hat, and it appears that Monty is Robotman's creator, though if I recall correctly, Monty was originally supposed to have been a space alien from the planet Moronia (and his mom resembled a lava lamp).

So my questions are:
Why and how did Robotman switch from Gary to Kevin?
Why and how did Robotman switch from Kevin to Monty?
Why and how did Monty's fat friend appear on the scene?
What is this fat friend's name?
Is Monty an alien or an Earthling?
Is Robotman an alien robot or an Earth robot?

I wouldn't worry too much about the consistency... here's quote from the creator: "In my cartoon just about anything can happen - this way, the ideas and characters always stay fresh."

But I can answer one of the questions!
What is this fat friend's name?
Moondog.

Moondog was described as an old frat buddy of Monty, so I assume that would make them both human (unless there are frats on other planets).

Wow, I guess I haven't followed the strip for very long--I didn't even know about Gary and Kevin.

I don't know how they explained away the original evidence for Robotman's extraterrestrial origin. But later in the strip they had a takeoff on "X-Files", where Mulder and Scully discover that Monty was originally a scientist working on a top-secret government project to create killer robots. The project was a flop, but one of the prototypes became Robotman. Montahue was subjected to brainwashing to erase his memory of the project, which transformed him from a genius to the total geek he is today.
