Reaper is unpredictable, chaotic, and what some may call evil. He likes being top dog, and will show everyone who opposses him where they belong, on the ground. However he loves playing around, making jokes, and hanging out, just as long as the others know not to challenge him. Even handlers will get the same treatment if they don't take extra caution to show him that they're in charge. However, for those he grows very close to, he will protect with his life, because after all, they are his.
