Arena: Stygian Depths

In the Red Corner, the psychotic Maverick mastermind, the steel-skulled enemy of humankind, from Mega Man X: Sigma!!!

And in the Blue Corner, the murderous poet, the divine destroyer of worlds, from Final Fantasy 9: Kuja!!!

The wily reploid scans the writhing walls of his hellish new environment. The searing heat distorts the very air around him as he unsheaths his beam blade and works his way through the maze-like catacombs. Kuja, lowering himself down to one of the stone platforms rising out of the boiling magma, inspects the tunnel openings in the walls of the cavern at a distance. Sigma emerges from one of the openings and the two combatants idenify each other instantly. Just as the two are about to make their first moves, a great rumbling unleashes itself in the bowels of the volcanic abyss. The walls begin to shake violently as debris rains from above, and jets of flame and lava erupt from below. Before long, the magma-line will have reached the apex of the cavern, while the ceiling caves in entirely. If either is to escape with their lives, they must act quickly to defeat the other, or else resign themselves to their demise by slow immolation or instant pulverization.
