Thanks to his demon abilities. he can see 10 second into the future to avoid attacks. This precognition has a side effect of causing nausea. He also have enhanced sense of smell when not in combat this allowed him to have a scent as good as a polar bear.

The con of this ability is he had to to chew on thing to get going with the form if he lost the a limb too often he'll pass out due to the stamina drainage
