Violent, reckless abandon, wild… familiar.
Riley still clearly remembers the very fight that he was able to finally fight Megawoman head-to-head, and this was the very same feeling.
Darmuid was physically stronger than James since each of his strikes causes total obliteration of anything unfortunate enough to stand in its way. James, however, no matter how finesse his movements, had this wild consistency in him that was similar to Aerith.
Clearly untrained professionally, but each strike showed experience that was crafted in true battle where losing means death.
"Show more of your tricks, alien!"
"When you've earned it, Lord James."
One would think their battle would have already decimated the land, but no. The terrain underground Theran was even more durable and sturdy than on the surface—there was also the fact that Riley and James, even after fighting for an entire minute now, still have not left the cliff they started fighting on.
This fight scene I did a little differently, dunno if it worked.
