Raphael (future) (Mirage)

Raphael is seen in various flashes to the future as having lost an eye, and becoming increasingly feral. He had trained Shadow Jones in the art of Ninjutsu, and in a quarrel, she gouged out his eye.

Trivia
Raphael missing an eye in the future is a recurring theme in the TMNT Multi-verse. It is also seen in TMNT Adventures, the 2003 series, and in Image's present day.
