===Sanity===
The topic of sanity has been addressed in many of the major heroes and villains of X-Men. Most famously this is addressed in Jean Grey when she gains near omnipotence through the Phoenix and [[Professor X|Professor Xavier]] after he violently uses his powers against Magneto, unintentionally creating Onslaught. Mystique's sanity wavers throughout the franchise as her constant transformations causes more and more of her mind to fracture.<ref>''Uncanny X-Men'' vol. 1 #289–290</ref><ref>''Uncanny X-Men'' vol. 4 #15</ref> Ever since swapping bodies with [[Kwannon (character)|Revanche]], Psylocke has occasionally struggled to maintain her sanity due to her more aggressive nature and new powers. The character Deadpool is famous for his blatant lack of sanity. After Magneto stripped Wolverine of his metal bones, Wolverine began to become increasingly feral throughout most of the mid to late 1990s X-Men comics. The nature of Rogue's powers affecting her sanity due to her retaining the memories of others has been a central plot device on many occasions, most famously retaining [[Carol Danvers|Ms. Marvel's]] psyche throughout most of the 1980s. Most recently Emma Frost's sanity has become fractured ever since Cyclops died in her arms, causing her to declare war against Inhumans.<ref>''Death of X'' #1–4</ref> Other characters who have had issues with sanity include Cyclops, Sabretooth, [[Magik]], [[Quentin Quire]], X-23, and Prestige.
