Magrik

Magrik was a Vogan guardian.

Biography
Magrik joined with Vorus in his plan to lure the Cybermen to Nerva Beacon where they would be destroyed by the rocket Skystriker. Although he was loyal, Magrik was frightened by Vorus’s plan and the thought of Cybermen nor did he trust their human agent, Kellman. He oversaw the construction and preparation of Skystriker. When the beacon was placed on a collision course with Voga, Magrik tried to launch Skystriker at it but was shot dead by Tyrum who had granted the Fourth Doctor fifteen minutes to get Sarah Jane Smith off the beacon.
