- "Three hundred dwarves lived on this ring. I thought if I did what he asked, they'd be safe. I made what he wanted: a device capable of harnessing the power of the stones. And he killed everyone anyway. All except me. 'Your life is yours', he said. 'But your hands... Your hands are mine alone.' "
- ―Eitri to Thor
King of Dwarves
Attacked by Rock Trolls
When the Bifrost Bridge was destroyed, the Rock Trolls, having coveted the Dwarven Forges for many millennia, attacked Nidavellir, knowing that Asgard could not come to defend King Eitri and his people. Using the power of the Tesseract, Heimdall was able to rebuild the bridge and aid Nidavellir; as a result, the Rock Trolls were defeated by Thor and the Asgardian army.
Forging the Stormbreaker
Nidavellir was later attacked by the Titan warlord Thanos, who forced the Dwarves to construct the Infinity Gauntlet so that he could better utilize the power of the Infinity Stones. Once they did so, Thanos proceeded to wipe out the Dwarves, leaving Eitri alive but with his hands taken so as to prevent further weapon forging.
Thor later came to Nidavellir in the company of Rocket Raccoon and Groot to see if Eitri had been there. While hiding away, Eitri began to attack Thor only to stop and realize that it was him. Sitting down, Eitri told Thor what had happened to his people by slaughtering them after he created the Infinity Gauntlet. To help stop Thanos, Eitri, with the help of the trio, constructed the Stormbreaker for Thor as a replacement for the Mjølnir.
Eitri is the Dwarf King as well as a skilled forger of weapons and armor, who is well known across the Nine Realms. Living in the forge of Nidavellir, he was good friends with Odin, king of Asgard, and even forged Mjølnir for him and was also brave and calm. Thanos, however, ruthlessly demanded the Infinity Gauntlet in exchange for his people's lives. But Thanos killed them anyway, leaving Eitri in a traumatic state. Unwilling to forge, or even light the never-ending forges of Nidavellir, Eitri lived a quiet, cowardly life, believing his hands to be unworthy forgers. Thor, however, while visiting him with Rocket Raccoon and Groot, reinvigorated his will to take up his craft once more. When Thor lit the forges again, this allowed Eitri to craft the Stormbreaker axe. Now, because of his reinvigorated happiness and spark to craft, Eitri is now pursuing his previous lifestyle: the way of the Dwarves.
Powers and Abilities
- Dwarven Physiology: Eitri possesses all of the various superhuman attributes common among the Dwarves. Despite the general misconception, Dwarves are much larger than Humans or Asgardians in regards to stature. Their sheer size grants them strength surpassing that of humans and even the average Asgardians. As the King of Dwarves, Eitri's physical power are much greater than any other member of his race and enough to seemingly harm even the royal Asgardians, shown when he could throw Thor away with a single attack.
- Superhuman Strength: Due to his size and status as King of the Dwarves, Eitri is the strongest Dwarf, thus holding considerable levels of superhuman strength. Eitri is strong enough to send a mature Thor flying with a kick. He was also able to crack and reshape the godly metal Uru with his arms.
- Longevity: As a Dwarf, Eltri ages much slower than a human being and has lived for millennia.
- "Eitri, this isn't about your hands. Every weapon you've ever designed, every axe, hammer, sword... it's all inside your head."
- Master Engineer: Eitri is legendary throughout the Nine Realms as a master blacksmith and forger, having forged Mjølnir, one of the most powerful weapons in the universe, stated by Odin to have "no equal". He was sought out by Thanos to forge the Infinity Gauntlet and even with the loss of his hands, he managed to partially craft the more powerful Stormbreaker, with some assistance from Thor and Groot.
