Weapon X

Weapon X was a comic book title published by Marvel Comics in 1995 (Volume 1), 2002 - 2004 (Volume 2), and 2017 - present (Volume 3). All three titles center on Weapon X, the secretive government research facility whose (often brutal) experiments on human test subjects led to the creation of characters such as Wolverine and Sabertooth. The series is based on the "Weapon X" story arc created by Barry Windsor-Smith in 1991 for Marvel Comics Presents.

Prelude (Series 2, Number 1/2)
The Director, the head of the Weapon X program, describes the current makeup of the Weapon X "team" of mutants, including Mesmero. The Director notes that the Weapon X program has greatly enhanced Mesmero's powers of hypnotism. Meanwhile, Mesmero is shown acting as somewhat less than a "model citizen" at a party.

"The Underground, Part II" (Series 2, Number 8)
It's another fine day for Mesmero as he uses his hypnotic powers to get whatever he wants. That is, until he visits his bedridden mother, who informs him that she is dying and that even his powers cannot stop it from happening. Mesmero is so shaken that he begins to lose his powers.
