What are Roger the Alien's powers in American Dad the animated series?

Roger the Alien, aka Roger Smith, is the alien member of the Smith Family in American Dad. I am curious - what are his alien powers, besides the following?:

Secreting a viscious substance that can be used as a mayo substitute
Making rainbows out of his urine
Making clones of himself- he did this twince in the series. In one episode one of his alter egos became a seperate entity, and in another he "dropped to his death" off of Niagara falls to make Stan's mother happy and then quickly resurfaced as a tour giude to a bunch of tourists there.
Go into trauma-induced slumber

What other alien things can he do?
He has superhuman leg strength- he used it to put the treehouse Steve and his friends were in, and that led him to pose as a competing wrestler against Stan.
He has the ability to probe people to share memories- he did it to Stan when Stan was drunk and he learned all of Stan's secrets, but Stan still didn't know anything about Roger. After Fran was run over by Stan's car Roger probed a doctor to find out how to do the operation to save her.
He has superhuman leg strength- he used it to push the treehouse Steve and his friends were in - FIXED.

Hi Natural, I assume you meant gold and jewels.
Making clones of himself- he did this twice in the series - FIXED.
