"Three Strikes and Osea can both burn in hell!"
― Rage[1]

Otto van Dalsen, callsign Rage, is a skilled pilot affiliated with GRGM. He is the flight leader of the mercenary Mimic Squadron, which is comprised of him and his sister, Elke van Dalsen.

Despite his aircraft sporting Osean Air Defense Force roundels, he is not aligned with Osea. He hides madness behind a veneer of calm, albeit better than his sister.


Sometime before September 4, 2019, Rage and his sister were hired by Osean Brigadier General Howard Clemens to kill the Osean ace Trigger.

On September 4, 2019, Otto and his sister engaged Strider Squadron, who were escorting an Osean fleet attempting to capture the advanced nuclear submarine, Alicorn. After engaging Trigger, Rage and his sister retreated from the airspace.[1]

During Operation Domino on September 10, 2019, Mimic Squadron once again attacked Strider Squadron, this time as they prepared to withdraw. Striking Lanza's aircraft with stealth missiles, the siblings engaged the 2 remaining Strider aircraft - Trigger and Count. As the dogfight raged, Clemens contacted the Mimic team on an open channel and ordered them to withdraw. Rage refused, telling Clemens it would be a blow to their reputation. Despite them using stealth missiles and ECM, the siblings were both shot down. In his final moments before his plane exploded, Rage cursed the name of Three Strikes, saying he would rather go to hell than live in a world shaped by Trigger. Rage's plane then exploded, killing him.[2]
