I mean, you can't expect the Galaxy's Greatest Foster Father Mu Suyin to produce quality artwork when all he's given is low-quality mooks, really, so them saving us all time and showing up with Space Baclavas is convenient for everyone, since it lets us know who is worth Proper Painting.
It's why he saves his painting expertise for important trash with faces, not their foolish mooks.
Also, I'm really amused at how he seems to have some ninja Shuras. They are Very Nice Gentlemen who keep showing up out of nowhere to have Very Polite Discussions with Ditu's soldiers.
