The Alien Chestburster Red Shirt Cake

Why is the alien coming out of a red shirt of Star Trek?

And one with the rank of captain, no less.

It's a good idea for a crossover comic book series.

Various possibilities:
1. It's a crossover event.
2. A comment on the long-running trekkie joke that if you played an extra in the original Star Trek series and wore a Red Shirt, you tended to die in some horrible fashion.
3. There actually was an episode of Star Trek: The Next Generation ("Conspiracy") where this type of parasitic critter burst out of a guy's chest and got phasered to oblivion by Picard and Riker; probably the goriest scene the show ever did. And yes, the victim was wearing a red shirt.

I know it's really obscure, but I was hoping it was based on this Comic Con cosplayer:

Yes, but that character wore the rank insignia pins of a lieutenant commander, not a captain.
