Babel – real name Christopher Newton – is a member of the Monster Makers, the group that designed and created the artificial life forms in the 1980’s that would become Digimon.
Roughly twenty years later, Babel and the other Monster Makers – sans Shibumi - were reunited by Yamaki and Hypnos, in order to learn more about Digimon, so that they could destroy them. However, when the Juggernaut system failed to destroy Vikaralamon, Yamaki was fired from his position.
Later, when Yamaki made contact with the Tamers, who had travelled to the Digital World to rescue Calumon from the Devas, he called Babel and the other Monster Makers together again so they could explain the situation to the kids’ parents. Babel and the others then started work on building an ark to bring the kids home. An attack by the D-Reaper on the Hypnos processor almost delayed their plans, but they were able to utilise the processing power of computers from all across the world to finish their calculations and send the ark into the Digital World to bring the children home. But it wasn’t over – the D-Reaper followed the kids back through to Earth, and immediately infested the Shinjuku area, causing the Monster Makers and Hypnos staff to flee the building. After they set up a new temporary base of operations, where Shibumi joined them, Babel was the one who used satellites to view the D-Reaper from above, and realised that it was staying away from areas of greenery.
The Monster Makers’ next challenge was to modify the ark – which had become sentient – into Grani, a “battle steed” of sorts for Gallantmon. It Bio-Emerged just in time to join the battle against the Optimizer. Later, Babel correctly identified the weapons employed by the Global Taskforce as magnetic jamming devices, before they had to move out of their temporary base and relocate. As their final strategy against the D-Reaper, the Monster Makers formulated Operation: Doodlebug, using MegaGargomon to create a vortex within the D-Reaper’s mass and activating the Juggernaut, returning the D-Reaper to the Digital World and devolving it to a harmless state.
After the tamers retrieve their partners from the Digital World, he continues to remain an active member of the Monster Makers and to assist Hypnos as needed.
