Yrcanos

Yrcanos was a Krontep warrior king whom the Sixth Doctor met on Thoros Beta in 2379. He later fell in love with Peri Brown. From the Matrix, it appeared that the enraged Yrcanos killed Kiv, whose mind was in Peri's body, but this was later proven false. The two escaped and eventually married.
