TF in Uncanny X-men 456-9

[Ironhorse]

Saw this in the comic a few days ago. Rachel Grey and the X men face off against evolved dinosaurs, who have their own superpowered dino x-men equivalents. One of which is a telepath, who half way through the fight telepathically causes Rachel Grey to transform into R'chel, an evolved sauriod. Rachel then aids the dinos in defeating the rest of the X men.

At first the change is only mental, although you do see her "mental image" change, and she walks like a dino and acts like one, but as the comic progresses she becomes more and more sauroid in body. It turns out that her subconscious is using her telekinesis to change her DNA to make her into a Sauroid. The sauriods realize this, but instead of doing something cool like using her power to rewrite all the xmen into X-dinos, they instead concoct a plan to use Storm's powers to destroy the earth and reclaim it for dino kind, which of course backfires and returns R'chel to Rachel and frees her from the mental control. Truly a pity.
