Wolverine has had many ups and downs throughout his life, but the time Magneto pulled out his adamantium skeleton changed his character's trajectory. This era of Wolverine lasted from 1993's X-Men (Vol. 2) #25 to 1999's Wolverine (Vol. 2) #145, a period of six years where Wolverine functioned without the fabled metal. Some fans look down on this era because of the way it led to his feral arc. Some fans still make fun of this noseless version of Wolverine but many of their complaints are overblown.
