Well, this is one of the moments you've been waiting for: The battle between King Toadstool and Lord Bowser. It's not very action-packed yet, but at least we'll get a glimpse at what the blood-infested potion does.

G.I.R.'s shadow: A Caceletta origin story? I might look into that, though I don't know much about her background. Of course, if I do make one, it'll be humurous...giving my fans a break from all this drama! (And is Gale of Darkness any good? I might wanna look into that too)

BassEX: You know his origin like the back of yer hand, huh? Well, then, what makes you think he's really dead? I just said they found his cape...

Kamilia had given him his potion. He had his War Hammer in hand. He had confidence and revenge in his heart. He was scaling the walls of Mushroom Castle. He had a score to settle.

He gazed down at the ongoing war, growing rapidly, bodies and weapons lying every which way. Bowser didn't seem to care anymore. He saw the dying Koopas, slowly deteriorating before his very eyes, blood flowing out of their helpless bodies like raging rivers, but he didn't care. Not then. It wasn't the time to.

Toadstool was still alive. He needed to end this once and for all.

He jumped up and landed firmly on the roof of the castle. His eyes darted every which way. He knew he was up here, watching his winning battle from above. Where was the coward hiding?

He suddenly heard the sound of a blade soaring through the wind at unbelievable speeds and ducked down in the nick of time. Toadstool swung even harder at the Koopa, missing by inches every time.

"Why do you even bother returning to me?" he scowled. "How can you even muster the imagination to think that you stand even the slightest chance?" He slammed his sword down again, nearly cracking, missing Bowser again.

Bowser gave him a look of utter hatred as he quickly stood up. "Good will triumph over evil tonight, Your Majesty!" He grabbed his Hammer by the hilt and gripped it tightly in his claws.

Toadstool grinned evilly. "A true man fights with a sword." His words sounded like slithering snakes emerging from a dark burrow. Bowser lowered his eyebrows.

"A true Koopa attacks with a Hammer!"

He roared and they burst into total melee. Nothing in Heaven or on earth could possibly stop them. Two beings, one a ruthless King, the other a chosen savior, clashing atop a castle with a shattered window, thunder and rain beginning to settle. Shouts and cries of war bellowed all around them.

They were evenly matched; Bowser slashing with his claws and swinging his Hammer, Toadstool kicking, punching, and stabbing. Sweat poured from each of their brows as their hearts raced. Toadstool didn't seem in any shape to fight, for he never thought he would have to resort to dueling with his own two hands. He always relied so heavily on his army…

His sword finally stabbed Bowser in the arm, forcing the Koopa to collapse onto his side. Blood trickled down his lower shoulder and down to his wrist. This was just like his first encounter with the dreaded King, who smiled triumphantly.

"Well, Lord Bowser," he snickered. "Looks like the jig is up. This little production of yours will finally draw to a close. My audience will cheer my name and cry out for my performance. They will look upon you and your pathetic attempts and mock." He raised his sword high above Bowser's head, ready to stab and kill.

"And you will not be missed."

Bowser tripped him with his tail. He didn't have a very long time at all. He pulled out the small bottle of ever-changing colored liquid. Once moment, emerald flashed before his eyes. The next, a deep sapphire. He swallowed the entire thing in one mighty, fierce gulp.

And the potion turned ruby.

Toadstool stood back up, rage filling his pupils. "DIE, MONSTER!" he shouted as he swung the sword down hard on Bowser's skull.

But the sword did no damage. Instead, it simply shattered. Eyes growing ever wide, Toadstool backed up as Bowser began to change. The first thing he noticed that changed was his size. He grew and grew, soon towering over the terrified King. His scales began to stretch and change in color, darkening from bright yellow to a sickly pale brown. His jaw grew enormously, resembling that of a dinosaur or a wolf. Jagged teeth began to poke at his bleeding gums, sticking out like swords. His tail grew until It was as if a whip. The yellow spikes on his shell began to grow as well, becoming longer and multiplying in numbers. His claws became like axes, bursting out of his hands and feet. His mouth smiled wickedly as his long tongue whip lashed this way and that, horrible breath consuming the air. Lastly, the white around his pupils began to glow a bright yellow as his once friendly eyes turned reptilian and evil.

Toadstool backed away slowly, turning a sickly shade of green before Bowser's ever-transforming eyes. Fear consumed the King entirely as he began to run as fast as he could towards the staircase. This new Bowser followed him, taking humongous steps, nearly cracking through the roof of the castle. Normally, Bowser would've taken a moment to look at his newfound strengths, admiring himself and killed Toadstool slowly. But that Bowser had lost control of his mind. Giga Bowser was in the driver's seat now, and he intended for it to be one hell of a ride.

(Now, before you all go off saying "GIGA BOWSER ISN'T BOWSER!" just remember...that this is Fanfiction not Nintendo of America!)
