When Manoel was twelve-years-old, and his siblings long gone from the home, his father gifted him a puppy โ a Brazilian Mastiff, to name and care for.
Manoel named the puppy Hammer, and they did everything together. Wanting to be with Hammer for as long as possible, Manoel trained him as a working dog, and enrolled in the military with Hammer by his side. First, he was part of the Guard Battalion utilizing Hammer as a guard dog, and later, moved his way into the Brazil Special Operations where Hammer’s hunting and tracking skills became invaluable in chasing down targets.
One day, on a tracking mission, Hammer was killed in action by the SpecGru organization. Manoel took Hammer’s name as his own callsign, and vowed revenge. He joined KorTac to do it and promised to never work with another K-9 unit, and to avenge his dog.
