Creepy Crawler was an artificial being created by Mojo from neoplasm who was created as a member of the X-Babies who was likely created after the original X-Babies returned to the Mojoverse after their encounter with Excalibur.
Some time after this, the X-Babies constructed the Clubhouse for Gifted Youngsters in the Umbrella Forest and were lead by Charlie X who was considered their "Big Brother". Here, the X-Babies tried to save the Pix from the Brotherhood of Mutant Bullies. Failing in their mission the X-Babies returned to their base, only to be attacked and captured by Centennials (Parade balloons turned into Sentinels). The X-Babies were forced to take part in a game show designed by Funhouse (an Evil Baby version of Arcade), which included both quiz and deathtraps. The group failed at the quiz sections but were able to beat the traps and were eventually freed by Cyke and Locksteed. Funhouse threatened to turn the Brotherhood back into neoplasm if the X-Babies did not return and they were about to agree to this when Charlie X showed up with reinforcements and saved the X-Babies.
