Every muscle in his right arm screamed, immediately throwing a punch like that after slamming into the tree on it was brutal. His pain was more than worth it, it gave him precious seconds on his opponent. Kanitah glared at Fury with a divine. . .Well, Fury. Immediately after his strike at the tree, Kanitah burst into a sprint towards the energy leech. The gap between them was entirely negligible at this speed, leaving Fury less  than a second to react. The old man brought both of his arms backwards, barreling towards his foe in a headlong charge. 

Before the gap slammed shut, Kanitah leaned forward with both hands thrusting forward. Fingers clenched tightly into bony fists, with every single pound of his weight and every fiber of his muscle aimed into a pair of titanic punches aimed towards Fury. His right arm thrust straight towards Fury's sternum, and his left arm aimed at where Fury's right kidney should be. 

(Though to be fair, Pundambayans have twin stomachs in the same place as human kidneys. So, he's actually aiming for his right stomach. )

With the full weight of his body and an angled strike to two sensitive areas, Kanitah intends to both knock the wind out of his foe, and to cause intense pain bodily pain.
