Elsa was born from Ulysses and Elise Bloodstone. Ulysses distanced himself from Elise and so she moved to England with her baby. Elsa grew up without knowing anything about her father, and her mother made sure she did not find out about his monster hunting career. Before Ulysses died, he entrusted Adam (a Frankenstein-like being that works as Ulysses' handyman) to give Elsa his Bloodgem choker. Elsa began having dreams about monsters and vampires, when they found out about Ulysses' death they flew out to his estate in Boston.
They arrive at the Bloodstone estate and are given a tour by Charles Barnabas (secretly a good pure blood vampire), who is the lawyer and executor of the estate. Elsa would later explore the estate against her mother's wishes to find a hidden chamber. There Adam would explain Elsa's legacy and heritage to her and give her the choker. A genie lamp in the chamber starts flashing and Elsa rubs it. She is then transported to Bosnia right in front of Dracula who is seemingly being pursued by some sort of special-ops soldiers. Dracula recognizes the Bloodgem and starts to close in on Elsa. The Bloodgem blasts Dracula away and Dracula was staked and caught by the soldiers, who it would later be revealed were servants of Nosferatu (another vampire). Adam arrives and brings Elsa back to the estate.
Elsa accepts the mantle her father left for her and so Elsa turns into a monster hunter, but she has to keep it a secret from her mother. Adam designs a costume for Elsa tailored like her fathers (and seemingly to maximize upon her already impressive cleavage, much to Adam's delight). The lamp would flash and Elsa and Adam begin another mission. This time the lamp teleports them to Egypt where they meet N'Kantu, the Living Mummy. They enter the pyramid to stop whatever is happening, leaving N'Kantu behind to keep guard, and giving N'Kantu the gifts of modern slang. Elsa and Adam would soon figure out that Nosferatu had Dracula captured and was trying to become powerful by sacrificing Dracula and other powerful "pure blood" vampires including their own Barnabas.. Elsa would confront Nosferatu and battle him, Nosferatu was able to bite Elsa in the neck. But the Bloodgem energy in her blood hurt him and so while Nosferatu was reeling from the pain, Dracula and Adam open a hatch in the roof to expose Nosferatu to sun light, killing him.
Elsa now lives in the Bloodstone estate with her mother and Adam. They also befriend Charles Barnabas who would help her on missions. Elsa began blogging about the monsters she has hunted and made an encyclopedia about all the monsters she killed in the Marvel Universe. Her first series of adventures ends with them setting out to combat a kraken.
Mayor Story Arcs
Elsa would later join Nextwave and in this series she claims that she comes from a long line of near immortal monster hunters (in another Nextwave issue, she says she is "second in a long line" of monster hunters stretching back thousands of years; i.e., her dad and herself). When she talks about her past in Nextwave, it differs radically from the Bloodstone comics.
In Nextwave she claims that she was trained by her father when she was young, such as dropping her into a pit with a monster as a toddler armed only with a spoon, and that when her parents were absent she was trained by a robot/torture device called "Hate Mother". It has been noted by the writer that they know her past differs a little bit and was used for the comedy of Nextwave. '' Civil War: Damage Report'' states that the memories and personalities of Nextwave members were altered by H.A.T.E. Elsa seems to have a strong report with N.E.X.T.W.A.V.E teammate The Captain, though whether this is just a friendly bond or anything more is open to interpretation.
Sometimes later, Elsa gets together with her teammate Boom Boom and they talk about their love lives and the men they have dated leading to an encounter with one of Elsa's ex-boyfriends, Franken's Teen, who Boom Boom blows into pieces. After that, Boom Boom and Elsa would still hang out and talk about what it would be like to be super-villains.
After her exploits in Nextwave, Elsa returns to her monster hunting ways. She hunts down the Children of Goram, offspring of a monster her father fought years before, in Prague. There she is impregnated by one of them, but the Bloodgem kills the offspring while it's inside her and she pukes it up. She is able to kill all the Children of Goram and in the end vows to kill all monsters before she dies (also vowing to be the last of the Bloodstone line, never to have a child).
Before the events of World War Hulks, Elsa fights alongside Robert Hellsgaard and her Nextwave teammates when a group of werewolves attack a town.
After the events of Siege, Steve Rogers, now the head "cop" of the Marvel Universe, writes a journal cataloging the main heroes of the world and discusses what makes them heroes. Elsa is said to be untrained and untested, but he sees potential in her. He also says that she still needs to be "watched closely, and hopefully she can retain her humanity in a very ugly line of work."
In between her monster hunting, Elsa becomes a staff member of the Braddock Academy, which is named after its headmaster, Brian Braddock (aka Captain Britain), and is "staffed by Britain's mightiest heroes." She along with others such as Meggan, Spitfire, and Union Jack hope to "make heroes out of Britain's best and brightest," which includes her relative Cullen Bloodstone.
Legion of Monsters
Sometime later, she joins the Legion of Monsters in regaining a piece of the Bloodgem from Frank Castle, aka The Punisher, when he is viewed as being controlled by the gem's "super demon." Although she is defeated in combat by him, she is saved by Werewolf by Night before the final blow is struck. He then is talked into giving the gem back to Elsa.
Sometime later while investigating the murders of teenagers in Chipperfield, Hertfordshire, England, Elsa comes across a monster that has been infected with a virus that causes monsters to go into violent rages. This again leads her to help the Legion of Monsters find the source of the virus and destroy it once and for all.
When a being known as the Dreaming Maiden started dreaming again, Elsa was shown what she desired due to her father being a member of The Covenant, a group that tried to kill the Maiden years ago but did not succeed in doing so due to deception by the assassin they hired, Wolverine. This led her to search out the Maiden to finish her father's work which brought her to meeting Wolverine in the present day. This also brought her into direct confrontation with Covenant members Murderous Lion, Jefferson Chambers, Wyatt Crowley, and a new female version of The Menace. After the Maiden had been killed, Vanessa Baker, another previous member of The Covenant, brought her and the other members together to "get back to business."
Her powers are partially inherited, and partially the result of the fragment of the Bloodstone she wears. She has enhanced strength, stamina, speed and durability, and an enhanced healing factor. Her blood is toxic to vampires. It is not yet known if she is immortal like her father.
Not having any offensive powers, she carries big guns. She owns some of the magic artifacts collected by her father, such as a genie in a lamp.

Forbush Vision Realm -
Elsa Bloodstone is one of a few hundred humans left alive on the planet. Operating under a self imposed Exile in Britain, she hunts the monsters the way her father did. Unlike her Father, Elsa only hunted monsters who threatened humanity directly. However, her Father hunted monsters with determination because he was breaking apart breeding pairs. It wasn't until the Cryptozoological Wars when Elsa realized the monsters weren't stupid, they forced nuclear states to attempt to sterilize their countries, and performed organized attacks on major cities. Now Elsa spends her final days killing the monsters in Britain.
