Bubonic Vaporizer is a British Mark-5 Jaeger created in 2026, its creation date coincides with the German Jaeger, Versteckte Destroyer. Its construction, unlike Versteckte Destroyer, was hastened during the Attack on West Germany due to fear of kaiju attacking Britain. However, this was not the case, as its first deployment was in 2028, 1 year and 2 months from its actual finalization. It is currently stationed in the West Midlands, in Birmingham. It was developed by the Royal Air Force, and piloted by twin brothers Gregory Davis and Aaron Davis.
Bubonic Vaporizer began construction after a series of energy signals in various oceans meaning that there were multiple portals, many more than just the pacific portal. Its construction was slow in the beginning, but was quickly hastened for fear of Britain getting attacked by kaiju after the attack on West Germany. It was equipped in both arms with I-9 Plasmacasters.
Bubonic Vaporizer's first mission (June 28th, 2028) was to use the body of Grafen to go through the Atlantic breach and weaken or destroy it, and kidnap a precursor for interrogation. It was seen that there was an unknown category kaiju guarding the entrance, codenamed Cerberus.
