After Cole MacGrath was named Patron Saint of New Marais for defeating both John White and Joseph Bertrand, he remained asleep in his coffin on a boat leaving New Marais. His friend, Zeke Dunbar was on the ship's deck when all of a sudden a lightning bolt struck Cole's corpse, reviving him and changed him into an ancient dragon named Thundestroy.
Zeke (suprised): Dang Cole, we never knew you were turned into a bigass, electrical bug monster. Did Bertrand slip you a roofie?
Thundestroy: Naw, it was Kessler who did that by forcing me to detonate the Ray Sphere back in Empire City.
Zeke: Oh, that's why they called you a terrorist back in Empire, but you being this bug-thing is new, wassup with that?
Thundestroy: Allow me to explain how I became this... dragon. My name is Thundestroy, one of the six Mino Guardians. Our job was to protect the planet from threats of mass destruction.
Zeke: Man, I thought that Mino Monsters was a mere game until you Cole turned into that.
Thundestroy: This isn't a game. Not anymore. My Guardian colleagues were Hydrabyss, Terrahorn, Infernova, Stratascend, and Blizziarc. When an ancient evil named Ragnarath and his five generals, Aquarath, Gaiarath, Sylvarath, Solarath, and Magnerath, declared war on humanity two milennia ago, we Guardians retaliated, but when we got our asses kicked by Ragnarath, Ragnarath ended up defeated by a hero named Sir Aaron, whom with the help of three powerful Minos, Gravolith, Blazonier, and Crocodon, sacrificed himself to help us Guardians and save humanity. Of course, Sir Aaron loved a woman named Queen Rin, so as a reward for defeating Ragnarath, Arceus reincarnated both Sir Aaron and Queen Rin into this day so they could love each other again. We Guardians, turned into stone pillars, waited patiently so we can await the return of the Hero of Evolution, Sir Aaron himself. Gravolith, Blazonier, and Crocodon, on the other hand, passed on to their descendants.
Zeke: Okay, I heard there was a pillar resembling you, Thundestroy, undisturbed at an art museum back at the Historic District of Empire City, before Kessler masterminded that Ray Sphere blast.
Thundestroy: Yes, I remember being a bike courier when that happened. When the Ray Sphere exploded, that Thundestroy pillar, along with Cole and the Electric Stones, became of one body. This fusion saved my ass from being killed by the blast, so I was the first of the Mino Guardians to be revived.
Zeke: No wonder you have electrical powers, thanks to Kessler. I wanted superpowers myself, but since I was not a Conduit, I couldn't have superpowers.
Thundestroy: I know. Hey wait a minute, I sense both Sir Aaron and Queen Rin at a region called Kalos. The Hero of Evolution is back in business.
Zeke: Well, I heard that a raven-haired dude named Ash Ketchum became a six-time Pokemon League Champion. His girlfriend, Serena Gabena, inspired by Ash, became a top-class performer in the Kalos Region.
Stewie: Oh, that's why Serena recognized Ash from a time before he was given his Pikachu.
Zeke: What the hell are a talking dog and a strange tyke doing on this boat anyway?
Brian: Hey fellas, I'm Brian, and this is Stewie. We came from a town called Quahog. It was wrecked alright.
Zeke: By the Beast?
Brian: Actually by a scuffle between Peter and the Giant Chicken.
Thundestroy: Nice to meet you two then. Well Zeke, we set sail for Kalos. It's about time that me and Sir Aaron had to meet again.
Zeke: Man, with Kalos having a French theme, I thought we were gonna miss the French culture back in New Marais.
Stewie: Yeah, me too.
The ship had set a course for the Kalos Region, where Thundestroy hoped to see the return of Sir Aaron and Queen Rin.
