Adam was shocked by Marco's great speed that surpassed even his, which was impressive considering how large and heavy his body must be.
He also seemed very skilled and combat, while was also confident in his body's defence, which was understandable after seeing that even Rex's bite could barely pierce his skin.
As he reached Adam, he went straight in for a fist towards Adam's face, which Adam narrowly dodged, seeing the attack coming, but was shocked to suddenly be struck in the side by a rapid kick.
His flexibility, agility and speed were all incredible and with such a large, powerful and durable body, he appeared to be the perfect fighter.
Adam put his arms up just in time to block the kick, but there was enough force and power behind the attack to launch him flying backwards.
