Ah, yes… much like Superman before him (and probably some other superheroes, too), by merely donning a pair of glasses (in this case, sunglasses), WonderBrat can render himself completely unrecognizable to those closest to him.
… and it helps when some of your friends aren’t all that bright to begin with… 
As a kid, I always hated that no one could recognize Clark Kent. All that changed was a pair of glasses and that little curl of hair that he let hang when he was super…
I also hated that about He-man. Wonder woman was pretty much the same thing.
Hey, Nef…
That always bothered me about Clark Kent too. And on the flip side, in the newer Batman movies, he’s wearing a full head mask, but apparently that’s not enough to conceal his identity – he has to talk like he’s been a chain smoker for 50 years, too! Where’s the consistency??
