Good day. Welcome to Undertown. Uh, durin' the next two hours or so, you're gonna see many fascinating sights, uh, alien wonders, and a universe of great bargains in the Undertown market stalls.

Toby Monitor.[1]

Undertown is a subterranean alien city under the Earth's surface. It is one of the major settings for Omniverse. Undertown is an underground alien settlement where many kinds of alien species live and thrive below Bellwood.

History

Omniverse

In The More Things Change: Part 2, Ben first discovered Undertown when he and Rook pursued Bubble Helmet, Fistina, and Liam underground after defeating them at Mr. Baumann's store. Ben discovered that Psyphon had been using Undertown as a base for his racketeering operations. Ben ended up fighting Psyphon, Bubble Helmet, Fistina, Liam, Thunderpig, and other unnamed henchmen of Psyphon while fighting Buglizard. After Ben fought off Buglizard, Psyphon and his followers were arrested by the Plumbers.

In Hot Stretch, Ben and Rook follow Ester to a deeper section in Undertown where the Kraaho made plans to make Earth hotter for them to survive and live in.

In Special Delivery, Ben made deliveries for Mr. Baumann to multiple citizens and businesses of Undertown in compensation for unintentionally destroying his property, in the process discovering a secret auction held by Psyphon, whose plans he foiled.

In The Frogs of War: Part 1, the town was revealed to humans for the first time as frightened Undertown citizens launched through the asphalt above and left Earth in search of another home.

In The Frogs of War: Part 2, the residents of Undertown return to fight off the Incurseans and work with the humans side-by-side, stating that they'll work on living together in Bellwood.
