In this great Issue of Uncanny X-men. The X-men are in part 2 of their battle with the Brood. Psylocke has debuted her new battle armoured suit. Encountering the super powered brood force in an alley, the X-men are beset upon. Storm is about to be dominated by the Brood woman Temptress, Storm breaks her hold and flees panicked.
Psylocke calls out to her, but is ignored. As she attempts to contact Storm, Rogue attacks Temptress but her mind is overridden. She uses this to her advantage, Psylocke although a Powerful Telepath, is quickly Dominated, putting up nowhere the resistance Storm did.
Entranced she joins Rogue(Temptress) in her attack on Wolverine, chiding Rogue for hogging all the fun.
Wolverine warns her about getting her wish. As Wolverine is pummeled, Psylocke closes the gap and attempts to Dominate Wolverines mind. He proves too much for her in his Berserker rage state. Leaping forward, he quickly knocks her out with a 1 hit KO. Psylocke flies backwards to the ground. She is then seen at the end of the issue, having recovered from the blow, her Armour absorbing much of the attack. She is still under mind control here.
I love issues where Telepaths are dominated, just goes to show, even they aren't mentally invulnerable.
