Desperation To Stop The Unstoppable.

He is faster and stronger. A new gate has a bigger impact than the little boost he gets from his armor. He reached the army quickly and caught them off guard. Even though the space was still larger, they didn't see him come at all.

They only heard a boom as he broke the speed of sound and then another boom as he smashed into their frontlines. But this time he didn't stop. He slammed into the army and continued as if they weren't there. 

His spear was thrust forward as he met the army. They parted like the waters of a sea as if he were the rudders of a ship. He cut through them and continued cutting. He was heading toward the catapults and nothing seemed capable of stopping him.

The defending army responded. The catapults were ready and prepped so they just had to aim. They didn't care for their comrades implicated in their attacks, they had orders from high up to "Stop that Aberrant Mutant at all costs."
