Johann Ibrahim Revil

In the Universal Century timeline General Revil (Also referred to as Admiral Revil) was one of the leading Earth Federation Space Force commanders. Before his appointment as head of the Earth Federal Space Force he was a Lieutenant General from the Earth Federation Army. Revil's biggest claim to fame was being captured by the Zeon's Black Tri-Stars after the Zeon destroyed Ananke, Revil's flagship, during the Battle of Loum. Shortly thereafter Revil, aided by Zeon traitors, escaped and returned to the Federation, where he made his famous speech: "Zeon is Exhausted!" from what he saw during his capture. This resulted in the Federation rejection of the terms of their surrender, although both sides agreed to a ban on nuclear, biological, and chemical weapons by signing the Antarctic Treaty.

Later, General Revil's fleet met in secret with Soverign Degwin Sodo Zabi to negotiate the terms of a Zeon surrender. Unfortunately, while both were mediating a peace, Gihren Zabi's ambition got the best of him and he ordered Zeon's solar ray weapon to fire at the rendezvous point, killing General Revil and Degwin, and eliminating most of the Federation's Revil fleet. With the loss of Revil and his command ship, the Phoebe, the remaining Federation ships in the Revil fleet regrouped around White Base and/or Luzar before launching the last attack of the One Year War: the Battle for A Baoa Qu.
