In the post-credits scene of The Fantastic Four: First Steps (2025), a TV is playing the opening sequence of a Fantastic Four cartoon. During that sequence, Reed Richards (Mister Fantastic) is fighting one of Doctor Doom's robotic Servo-Guards in what looks like a laboratory and uses some kind of beam device to shrink it down to nothing. After the robot is gone, we briefly see what appears to be an insectoid, caterpillar-like creature, presumably one Reed Richards is studying, inside some kind of specimen jar in the background.
Is this a creature from the comics? What is it?
