Raizer Omega is the name of the highly advanced Jaeger that was created from the wreckage of Epsilon Crux after it was blown through the breach and into the Anteverse. It is the fifth and final Jaeger of its kind. Raizer Omega is piloted by Fightmaster Lancaster, serving as the master pattern for many other unique Jaegers which are being modeled after its design. Towards the end of The Second Human-Kaiju war it descends from a forcefully opened interdimensionary breach created by Mara Kraff and her hyper advanced Hadron Technology in order to send the weapon and its pilot back into the human world so as to end the war once and for all. Raizer Omega serves as the integral and most valuable part of creating "The Matchless Warrior".
