Leland made subsequent posthumous appearances in Classic X-Men #7, Sensational She-Hulk #34–35, Marvel Super-Heroes #11, Generation X #-1, X-Men: Hellfire Club #4, X-Men Unlimited #6, and House of M: Avengers#5.
Fictional character biography
Hellfire Club
Little is known of Leland's past before encountering the X-Men, although he did encounter former teammate, Emma Frost, before she was inducted into the Hellfire Club. At the time, Emma was homeless and using her powers during a Hellfire Club meeting to gain information about stocks. Leland takes an interest in her but comes on too strongly, and Emma runs away. Shortly after, he accompanies Sean Cassidy and his NYPD partner to an incident behind the club which involves Emma. Emma, having met and repaired the fractured mind of the Dark Beast with her powers, mind-wipes all three men into forgetting the incident and that they had ever met. Leland encounters the X-Men when they invade the New York headquarters of the Hellfire Club. Leland causes Wolverine to become increasingly heavy until he falls through the floor into a sub-basement. In the rematch, Wolverine attacks Leland from above. Leland panics and uses his mass-increasing powers, resulting in Wolverine crashing through the floor again, this time with Leland beneath him. Leland is hospitalized as a result. When the Hellfire Club again captures the X-Men weeks later, Leland takes revenge by using his power on Wolverine until his heart gives out, though his rival's death proves to be a temporary state induced by Amanda Sefton. Alongside the Hellfire Club, Leland battles the X-Men in New York'sCentral Park. When Nimrod attacks the assembled mutants, the X-Men and the Club join forces to battle Nimrod. Leland increases Nimrod's mass to make it more vulnerable to attack. Overweight and in poor health, the effort triggers a heart attack. At Storm's urging, Leland increases the mass of Sebastian Shaw, causing Shaw to crash into Nimrod. Leland succumbs to his heart condition and dies.
X-Humed
The supervillain Black Talon revives Leland's body as a zombie, and sets him and other undead mutants against She-Hulk. She defeats them, and Leland is reburied, with precautions are taken to ensure that he never will come back, among them filling his mouth with salt and sewing his lips together.
Despite the precautions made to prevent Leland's body from coming back as a zombie, the psychic vampireSelene revives Leland with the use of a modified version of the Transmode virus during the Necrosha storyline. Leland is sent to Utopia with Shinobi Shaw, who was revived by the same means, to kill Sebastian Shaw, Donald Pierce, Emma Frost, Magma and the X-Men.
Powers and abilities
Leland possesses the ability to increase the mass of an object or person within of him, without affecting its size at all, making it increasingly heavy. Though he can only increase mass up to roughly 20 kilograms per second, there is seemingly no limit to the total mass he can add to a person or object. Leland's power can affect both people and inanimate objects, but active resistance by the subject makes it more difficult to assert Leland's power. Leland is overweight and in poor health, and thus he is a poor hand-to-hand combatant.
