The time has come as the Ultra-Rip-Zipper has been finished. The others are around as they plan their next move.
Clemont: All we have to do now is set up the Ultra-Rip-Zipper. Rotom says that we should take it as close to the Rip as we can get it… and by "close" I mean "the top of the volcano"...
Goh: With how powerful the winds generated the Rip is making, flying there on our Pokémon would be risky.
Ash slammed his fists together with a smile.
Ash: Then we'll go inside the volcano then!
Goh: It wouldn't be easy, but we'll pave the wave for the others to safely travel while they bring in the Ultra-Rip-Zipper.
With the plan in progress, the kids are ready to start their final journey.
Ash: Alright! Let's go!
At the feet of Volcano Mountain the kids arrived on their flying Pokémon as they mounted off. Ash, Goh, Iris, and Dawn looked at glowing ooze flowing beneath cracks as they came out of the cave.
Ash: Alright, we're here!
Clemont: Be carefull, guys! This place is wall-to-wall ooze!
Clemont was right as the inside of the volcano was a river of ooze.
Dawn: How are we gonna cross this?
Iris noticed the stalactites on the ceiling and had an idea.
Iris: I know! Come out, Haxorus!
Calling out her faithfull Pokémon, Haxorus stood ready to help Iris.
Iris: Use Psycho Cut on those stalactites and bring them down!
Haxorus unleashed his psychic blades that cut the stalactites and made them fall into the rivier as they turned into a bridge for them to cross.
Ash: Good job, Iris!
The kids and their Pokémon hopped on the pillars as they've reached the other side, where a stone door with a face stood. The door opened by itself when the kids that close to it, but then they noticed to their surprise that something was behind the door.
It was a huge army of Ooze Monsters, which looked the same as the Sand Monsters but made of rock and ooze.
Goh: How are go through all of them?!
Ash: That's easy!
Ash turned his hat backwards as he pulled out all of his Pokeballs.
Ash: Through battle!
Ash then called out all of his Pokémon. Lucario, Gengar, Dragonite, Dracovish, Sirfetch's, and lasty Pokémon stood in front of the army.
Dawn: Alright, us too!
Dawn and Iris called out their Pokémon. Piplup, Buneary, Pachirisu, Quilava, Mamowsine, Togekiss, Haxorus, Emolga, Excadrill, and Garchomp appeared as well.
Goh: We did have to make a path for the others anyway… alright guys, you too!
Cinderace, Drizzile, and Grookey now stood ready to fight too.
Ash: Now go!
Sirfetch's charged in followed by Dracovish, who's lower jaw turned to ice. Gengar fired a Night Shade from his eyes while Lucario used Double Team to multiply himself and unleashed a barrage of Aura Sphere's and Dragonite unleashed her Hurricane attack, followed by Pikachu unleashing Thunderbolt.
After the loud explosion Dawn was riding on Mamoswine who fired Ice Shads. Buneary then froze the feet of the Ooze Monsters with Ice Beam, followed by a combination move of Piplup's Whirlpool and Pachirisu's Discharge that washed and shocked the monsters. They were then showered by blue energy blades, which is the Air Slash from Togekiss.
Haxorus and Garchomp unleashed a double Dragon Pulse that combined into one large blast. Dragonite then fired a Flamethrower, followed by Emolga's Volt Switch and Excadrill Focus Blast.
Cinderace then kicked a lone monster into the air with Double Kick, where Drizzle sent it back to earth with a tail-Pound attack. Grookey then came and started hitting on the unconscious monster's face with his stick.
All this ruckus created from the battle caught the attention of the evil that resides on top of the volcano, who already figured who they are.
?: So… they finally chose to come and face me. (Chuckles evilly)... Let's see if they have what it takes…
After a while of climbing and fighting, Ash and his friends have reached the very top of the volcano. Ash then called Clemont to tell him to bring the others with the Ultra-Rip-Zipper.
Ash: Alright, Clemont. All clear to the top. You guys can come on up!
Clemont: You got all the monsters, right?
Ash: Believe me, we got all of them.
Ash then turned off his communicator as he turned to his friends… but then, someone rose from the volcano and stood before them. The Mawgu!
Mawgu: Chosen Ones! Behold your doom!
The Mawgu looked like an Ooze Monster, but huge, well built, and doesn't have any legs as he seems to be flying. Ash and his friends were on guard as the Mawgu addressed them
Mawgu: I choose you… for destruction!
The Mawgu then flew up into the purple storm as the others watched. Pikachu's cheeks sparked electricity as he and Ash glared at the one that's causing them all their troubles.
Iris: So that's the Mawgu…
Goh: He's more intimidating than I expected!
Ash: Guys, let's defeat the Mawgu and save this world and our own!
Everyone got their motivation back. Ash always knows how to lift back their spirits.
Dawn: You're right, Ash! No need to worry!
Ash: Look out, Mawgu! Here we come!
