Hey, cartoon watcher here. I have a few questions for the comic readers?

1.) So I know the Maulers have been cloning themselves for years, but why are they blue, fairly durable, and really strong?

2.) In the second season, it's very heavily implied, if not outright confirmed that Donald is an android/clone-cyborg replica of his original self. Is this the first Donald clone? If not, how did Donald dodge a punch from Omni-Man ROFL?

3.) This is kinda random, but did Mark need the medical equipment to recover from his wounds during all his ass beating?

4.) Does Rudy have Rex's powers? If not, how did Rex get his abilities?

5.) Do viltrumites get a lot stronger as they age, or is it related to how much they fight/work out?

6.) Why does the show say Alan can't beat a viltrumite when he very clearly can in a 1v1

thanks in advance
