MMW4 was assigned to travel to the Blue Planet to spread LEGO Universe's plea for help. As MMW4 traveled to the rip, Pod 4 was unrelentingly pursued by the Maelstrom. MMW4 tried to maneuver away from the Maelstrom, but was unable to escape the menace. He broke protocol and performed a log override to warn his fellow Pod pilots about his encounter. Upon passing through the rip, MMW4 lost his mobility.
MMW4 was discovered by Andrew S. in Illinois on December 18, 2009. While MMW4 does not appear in LEGO Universe, Andrew S. received an in-game reward for finding Pod 4 and MMW4: the Pod 4 Shirt.
MMW4 bears the emblem of Assembly, hinting that he is a member of Assembly.
As a result of MMW4's encounter with the Maelstrom, the flight paths of Pods 6 and 7 were adjusted to avoid the menace.
