A Mario and Luigi Brothers Short Story: A New Foe

Mario began to open his eyes in a bleary state with his head feeling like a hammer had hit it. He looked to his left and right and noticed he was chained to a stonewall. The only thing in front of him was a smooth marble path with lava on either side that lead to a huge wooden door, which was closed.
"What's going on?" Mario said out loud. First I was in a forest smooshing goombas and then I wake up to find myself here in this stone room?"
Ssshewwwwmmm! The lava beside the marble path began to spew upward and a huge bulky figure was standing in front of Mario. Mario stared hard at the thing, taking in its physical characteristics. The body of whatever it was, was made up of what looked like hardened magma, except for the legs that were purely lava. The figure's face looked like a skull with flames surrounding its head. It wore a crimson cloak on its back that was connected to its volcano-like shoulders. The thing also carried a long, red-wooden staff in his hands.
"Greetings, Mario. Enjoying your stay here in my humble castle? I hope so, because you're going to be here for a LONG time."
"Who are you?" Mario asked the mysterious figure.
"Me? Why, I am King Brimstone, King of all lava and magma, and Lord of this castle."
"Are you another of Bowser's cronies?"
"Another of Bowser's cronies!? Har-Har-Har! That's a good one. I don't work for that overgrown flub of a turtle. This is all my doing. Quite ingenious of me to have captured you when he merely tried capturing the Princess neh?"
Mario turned his head. "Well, if your going to destroy me, get on with it."
"Oh not yet my boy, Iv'e got big plans for you. and it involves a certain little kingdom which you love so dearly."
Mario turned his head at the mention of the Mushroom Kingdom. "What are you planning!?"
"Fiesty now aren't we? You'll know soon enough what my plans are, shouldnt be too hard to figure out. Well, I have some things that need my attention, do enjoy your stay here while I'm away, and don't think about escaping, if you could, there are two guards standing watch outside the door, and they are in a rather cranky mood, wouldn't want to upset them further now would we? Ha-Ha-Ha!"
With that, King Brimstone jumped into the lava, disappearing with a his while his voice echoed all around the room, leaving Mario to ponder what it was that King Brimstone had planned for him and the Mushroom Kingdom.
"How can I stop him when I'm chained to this wall, and don't even know what his plans are? Who else could possibly stop him?" Mario said silently to himself.
