Ever wish that George Lucas would go further into a what if scenario about Vader being a good father and not the deadbeat not there dad that he was? In his defense he didn't really know that Luke and Leia existed. But he would still be half human half robot and would probably scare the crap out of every little kid!
This great drawing explores everyday things that a father and son might go through, but this is with Vader and Luke instead. It's from Jeffrey Brown's Darth Vader and Son.
