"Yes, yes Bam, the legendary titan of earth doesn't use ground based attacks to enter his secret home." Jeraldo mocked Bam as they proceeded down the stairs. The stairs kept going down...and down...and down, all the while getting hotter and hotter and hotter.
Finally, a large door-like hole emerged from the bottom of the steps. The group catiously stepped in, examining all that they could. It was a massive room, ringed with lava, the ceiling impossibly high for a cave, and on the opposite side of the room was a small passageway. Despite most of the wall looking like it had been smoothed and even polished at one point, there was now ragged claw marks, and even some holes dug into the walls.
"Well...I thought for sure a room like this would have had Groudon in it, come on, let's go deeper in." Jeraldo mused out load.
"Wait!" Shouted out Bam, "GROUDON, WE CHALLENGE YOU TO THE ULTIMATE FIGHT OF WARRIORS, SHOW YOURSELF WEAKLING!!!"
Before Jeraldo could scold Bam for doing something that stupid, a large, hideous grinding started emitting from the extremely high ceiling. Suddenly, a blackened claw ripped through, then the arm attached, and then a huge pokemon fell all the way down to the bottom and landed infront of the group, roaring a malelovent screech. Its fangs dripped blackened spittle, the intercrossing lines that flowed across its body glowed a palid, sickly red, the eyes were a dull ochre, and everything about the pokemon looked diseased and nearly rotten...
...Groudon had come.
