Elliot Randolph is an Asgardian who chose to stay on Earth (Midgard) after a battle centuries ago. The name "Elliot Randolph" is presumably an alias, though his true name is unknown. Randolph has possessed the "Berserker Staff", which he broke into three pieces and hid across the globe. Randolph is a professor of Norse mythology and masquerades as a human.
The Asgardian who would come to be known as Elliot Randolph was a stone mason for thousands of years before being recruited for a military mission to Midgard in the 12th century. Tired of his mundane existence in Asgard and desiring to travel the Realms, Randolph signed on.
While on Earth, Randolph served with an Asgardian army called "The Berserkers" who gained superior strength, even by Asgardian standards, by touching a device known as the Berserker Staff, which brought all of the rage and hatred that the wielder keeps suppressed and transforms it into strength.
During his time on Earth, Randolph fell in love with the planet and its people, and when the rest of the Asgardian host returned home, Randolph stayed behind. The Berserker Staff was left behind as well. Randolph, who now considered himself a pacifist, did not want the staff or the power it possessed. Fearing that the dark magic of the staff would fall into the wrong hands, he broke the staff into three pieces and spread them in various places across Europe. He hid one in a tree in what would become the Trillemarka National Park in Norway, one in a crypt in Seville, Spain and the final piece in a church in Ireland.
Randolph lived on Earth for several centuries when in the year 1546, he met and fell in love with a French girl. He told her his story and her brother, who happened to be a priest, wrote the story down and created the legend of "The Warrior Who Stayed."
By the 21st Century, Randolph had taken up the guise of a human professor of Norse Mythology at the University of Seville.
Two years later, when the piece of the Berserker Staff that Randolph hid in Norway was found by a Norse Paganist Hate Group, Coulson again consulted with Randolph. Randolph, recognizing what they were searching for, tried to find the pieces of the staff before either S.H.I.E.L.D. or the neo-Norse pagans could.
Unfortunately, Randolph could not keep the staff piece out of the hands of the pagans, and was taken into custody by Coulson. Coulson, after deducing that Randolph was the legendary Asgardian "Warrior Who Stayed", got Randolph to cooperate by threatening to reveal his Asgardian origins to the world.
Randolph led Coulson's team to the church in Ireland where the final piece was hidden, only to find that the Paganists had beaten them there. One of the Paganists stabbed Randolph through the heart with a staff piece.
Agent Coulson managed to keep Randolph alive long enough for his advanced Asgardian physiology to heal itself. While this happened, agents Grant Ward and Melinda May utilized the staff to take out the Paganists.
Afterward, S.H.I.E.L.D. took the Berserker Staff into its possession and Randolph decided that given Europe's new fascination with all things Asgard that it was perhaps time for him to move on. Coulson recommended that he move to Portland, Oregon, and agreed to visit him there.
In "Purpose in the Machine", Coulson asks Randolph for help in understanding the Monolith and hopefully bringing Simmons home. However, Randolph refuses to help for fear that if the Monolith really is some kind of portal to an alien world then they might try to use it to send him back to Asgard. Coulson, however, threatened Randolph that if he didn't help them then he'd expose him as an Asgardian and turn him into the ATCU. Randolph agreed to help, but only on the condition that after Simmons returns they destroy the Monolith.
Randolph recognized the symbol on the scroll Fitz found and explained how another translation of it is "death by punishment". Randolph further explained how he saw the symbol in 1853 carved into the walls of an English castle while attending a costume party and investigating rumors he heard about travels to the stars. However, Randolph found out the Monolith was merely used by a satanic cult as a means of human sacrifice and stopped searching for it.
Elliot Randolph possesses all the superhuman physical attributes associated with any Asgardian Soldier.
- Superhuman Strength: He has the natural strength of an Asgardian male. He was able to bend Grant Ward's knife with complete ease. He even claimed that he can go through Leo Fitz literally. He also broke the Berserker Staff with his bare hands.
- Superhuman Durability: He has the durability of any Asgardian male. While immune to damage caused by ballistic attacks or other human weapons, he was seriously injured by the Berserker Staff.
- Superhuman Agility: He also has the enhanced agility and speed of any Asgardian.
- Superhuman Stamina: Like any Asgardian, He tires much more slowly than the average human being.
- Healing Factor/Regeneration: As with any Asgardian, his natural healing abilities are much faster than those of a normal human being. He was able to regenerate from fatal wounds received by the Berserker Staff within a few minutes.
- Superhuman Longevity: He is an extremely long lived, which is again typically Asgardian. He has lived on earth for more than 3000 years with his physical appearance resembling a man in his early 40's.
- Combat Skills: Because he was an Asgardian warrior, he may still possesses his combat abilities, though they may have weakened over the years, due to lack of practice.
- Archeology: He has, presumably, an extensive knowledge of literature and mythologies in particular, given his hundreds of years on Earth, and current profession, as well as being an actual Asgardian.
