Doop's abilities displayed in the comics thus far have included superhuman strength and durability, flight, regeneration, physical malleability, a vaguely defined ability to manipulate time and/or space, and the ability to replicate physical objects by unknown means. In the "silent" issue of X-Force, he accidentally sucked the entire team into his body or mind via a popped pimple. He entered himself by picking at the pimple, and rescued his teammates from their own subconscious minds. When they were restored to reality, none but Doop was aware of what had occurred, and only a fraction of a second had actually passed. Doop uses his mouth as a storage space for his camera equipment, among other items; it is unknown whether these items are simply stored inside his physical body or are actually transported to another dimension like the one to which his teammates were transported. In the "Lacuna" storyline in X-Force, Lacuna's ability to stop time did not affect Doop. Whatever his control over time or space may be, it is apparently not powerful enough for the team to use him for teleporting the group; they relied first on U-Go Girl and later on Venus Dee Milo for long-distance travel.
In the "X-Statix vs.Avengers" storyline in X-Statix, Doop's brain was removed from his body and forced to project energy blasts at his teammates (a power that he did not demonstrate previously or afterwards). The brain was accidentally smashed into fragments by Thor, but his second brain (located in his hindquarters) was temporarily installed in his head until the original brain could be reassembled (not unlike the Star Trek episode "Spock's Brain"

. Later, when Thor struck Doop with his hammer, Mjolnir, Doop absorbed the hammer into his body and fired Mjolnir and a number of duplicate hammers from his mouth at Thor. Doop has stretched his facial features and tongue on numerous occasions, and once pluckled an eye from his head and then replaced it. He expanded his body into a cushion in the Wolverine/Doop miniseries. It is unknown if Doop possesses any other powers. On the one instance where he was forced to kill someone, he apparently used an ordinary axe, although the killing itself was not actually depicted on-panel. Some time later, when Doop thought that Wolverine was dangerously insane, he was prepared to attack the X-Man with a broken glass bottle.
A figure of Doop was included with the Marvel Legends Wave VI Deadpool figure. Doop merchandise is also popular in the Marvel universe, particularly among children; Paco Perez was seen wearing a Doop t-shirt, while Molly Hayes is the known owner of both a stuffed Doop doll and Doop poster. Jean Grey has also been seen with a Doop keychain.
