At one point, during a period in which the then thought-dead X-Men had disbanded, the mutant heroine Psylocke passes through the mystic portal known as the Siege Perilous. The portal relocates her to an Asian shore, leaving her an amnesiac. The man known as Matsu'o Tsurayaba finds her and believes he could save his brain-dead lover Kwannon by switching her mind with Psylocke. He makes an arrangement with the Mandarin to help him with the switch, since his rings will be able to facilitate it. Working with the otherdimensional sorceress known as Spiral, they are able to do this successfully. The Mandarin conditions Psylocke (now in Kwannon's body) to believe herself to be Lady Mandarin, the Mandarin's assassin. During this time, the Mandarin teams up with several other villains during the "Acts of Vengeance" storyline. He also confronted the Avengers. After completing several assignments for him, Psylocke is eventually rescued by her X-Men teammates Wolverine and Jubilee. The three then defeat the Mandarin, causing events which lead to the severing of the Mandarin's relationship with the Hand.
