Thor: 10 Mortals Who Wielded Asgard's Weapons
5. Bullseye
If there is one character in the Marvel universe you DON'T want getting his hands on a weapon that belongs in Asgard, it's Bullseye.
Bullseye's whole thing is that he can instantly make anything lethal just by holding it, so imagine the damage he could do with - say - the Valkyrie blade Dragonfang, which by itself already boosts the offensive capabilities of whoever wields it.
Actually, you don't have to imagine it, because Bullseye showcases how dangerous such a weapon is in his hands when he viciously murders Heimdall right in front of Jane Foster, during the character's first stint as Valkyrie following the events of War of the Realms.
Of course, this is not an advantage that lasts long for Bullseye, seeing as how Heimdall is rather beloved by the other Asgardians, so killing him is guaranteed to make them rather upset. This means he doesn't get to keep his prize for that long before Jane gets it back, courtesy of a little help from her faithful Yorkshire steed, Mr. Horse.
