Not just Blue Beetle in his uniform from I Can't Believe It's Not the Justice League. No, no. This is the evil Mirror Universe Blue Beetle.
If you read the story, the "Super Buddies" wind up on an alternate Earth after leaving Hell (Don't ask!). This Earth had evil dopplegangers of some of the heroes (including a dominatrix Mary Marvel! Hotcha!). At one point Mirror Sue Dibny asked Mirror Max Lord why our Beetle was "wearing Teddy's costume". So, although we never got to see the Mirror Blue Beetle, we know he exists, he wears the black costume, and he doesn't look like our Ted Kord.
So how could I make him look different?
See the van dyke? That's a dead giveaway he's EVIL! (basic STAR TREK 101)
