The true origin of Doop is still unknown, but the strange creature first came into continuity as the new X-Force's cameraman. The team was founded for one simple goal, making mutants hero celebrities. While the team would fight battles, sometimes against impossible odds, Doop would record it on camera for the TV shows. During this time, he helped his team out more then just once, but could not help seeing many of his teammates perish anyway.
Doop was created by Peter Milligan and Mike Allred in 2001 and first appeared in X-Force #116.

X-Force and X-Statix
Doop is well known throughout the superhero-community as well as a fan favorite to the t.v. watching audience. He is a close friend to the X-man Wolverine. After the death of X-force founding member U-Go Girl during one of the missions, the team changed it's name to X-Statix. Doop followed his teammates and joined the team. While in search for a replacement team-member to U-Go Girl, the team came across a mutant named Corkscrew. Already on his first try-out fight, this mutant killed a rival for the job. X-Statix figured out this was not the mutant they where looking for and asked Doop to 'take care of it". Doop then took Corkscrew out in the woods alone and "took care of him" by chopping him up with an axe.
In one of the X-Statix's missions, Doop's brain exploded, letting 5 pieces of his brain drop all over the world to different locations. While X-Statix tried to re-assemble the brain, they got rivalry from the superhero team known as the Avengers whom also joined together in order to re-assemble the parts of Doop's brain for their own purposes. A hunt for the brain parts started, with in most cases, X-Statix being the ones whom got away with the price. At the end of the hunt, Doop's brain was brought back together save one piece. This however did wake Doop up, since he was able to live and function on his second brain. He fought against Thor for the last part of his brain, won the fight and successfully restored his whole brain. In that fight, he also demonstrated that he is considered worthy enough by Thor's mystic hammer Mjolnir to lift and wield it. It was later suggested by Captain America that Doop was a weapon made by the US during the Cold War that was essential in the defeat of Russia. Doop allegedly died by gunfire along with the other X-Statix in their last mission.
Although Doop allegedly died by gunfire along with the other X-Statix in their last mission, another creature that is possibly Doop (due to the identical looks) was found by Polaris and Havok in Costa Rica. Due to the uncanny resemblance, they named the being Daap. It is still unknown if the two are the same or just from the same species.
Nation X and the Jean Grey School
Doop appeared in Nation X #4 while trying to solve a mystery on the X-men home-base island of Utopia with his good friend Wolverine. He even followed Logan back to the newly rebuild Xavier school, now named the Jean Grey School for Higher Learning, when Wolverine went back there with a few X-men after a fall out with Cyclops on Utopia. There Doop seemingly was always relaxing and sleeping, much to the annoyance of other staff-members. This could however not be further from the truth as it turned out that Doop had long days and nights taking out possible threats to the Jean Grey School.
When Doop first spoke in X-force 116, Doop's words where just non sensical texts. However, the code was cracked and Doop's language can now be read thanks to this handy guide. Try it yourself with any comic starring Doop in X-Statix, it is readable! (Image (c) and tm UncannyXmen.net)
Doop has many powers and many that are unrevealed.
While he has demonstrated certain abilities, other powers are attributed to him by various sources which are not clearly backed up by canon evidence. The powers he has actually shown are:
The ability to extend a long, prehensile tongue.
Energy blasts from a fragment of his brain.
The power to inflate himself.
Enough strength to knock down Thor.
The power to protect himself and others from psychic or telepathic detection.
Immunity to time manipulation.
The power to safely have body parts removed and put back together.
Storing improbably large objects inside himself.
A small backup brain allows him to survive for a few days without his main brain.
Possibly the ability to duplicate objects, as when he produced a swarm of hammers to attack Thor. (Or he may have simply been storing hammers in himself for some reason.)
Doop's pimple also apparently contained a timeless pocket world in which living beings live out their nightmares.
Although he can only communicate in "Doopspeak", he somehow manages to get his point across to those who have known him for a while.
