Boom Tube

A Boom Tube is an extra-dimensional portal used to instantaneously travel vast distances. It is used by the New Gods via Mother Boxes to travel throughout space without the need for a ship.


Invasion of Earth

Thousands of years ago, when Steppenwolf invaded Earth, he was defeated by the joint effort of the Amazons, Atlanteans, and Humans, with assistance from Yalan Gur of the Green Lantern Corps and the Olympians. During the battle, his ships were destroyed, forcing him to flee through a boom tube summoned by his Apokoliptian Priests.[1]

Attack on Themyscira

When Steppenwolf returned to Earth, he arrived from a boom tube opened in the vault in which the Amazons guarded one of the Mother Boxes the New God arrived with centuries ago. After defeating the Amazons and reclaiming the Mother Box, Steppenwolf summoned a boom tube, allowing him to escape.[1]

Assault on the Atlantean Vault

In pursuit of the Mother Box held by the Atlanteans, Steppenwolf sent his Parademons to retrieve the Box secured in a vault beneath the ocean. When his soldiers failed, Steppenwolf appeared, defeating Aquaman and Mera, as well as multiple Atlantean Royal Guardsmen, before summoning another boom tube to return to his fortress in Russia.[1]

Return of Superman

Following the Skirmish in Heroes Park, Steppenwolf retrieved the final Mother Box by using a boom tube to steal it while the Justice League was distracted.

Battle of Russia

Following his defeat by the Justice League, Steppenwolf was dragged into a boom tube by his Parademon soldiers.[1]
