Gyarados

Gyarados is a Water/Flying Pokemon.

It evolves from Magikarp starting at level 20. It can also Mega Evolve using the Gyaradosite.

Cyrus had a Gyarados that eliminated Gigawatt the Luxray from the Platinum Nuzlocke in XD with Earthquake. That Gyarados would later make Michael cry in 2017 best Pokemon video immediately after the considered late Luxray is mentioned, and the species itself even lost the title of best Water Pokemon in the video named "Top Pokemon of Every Type", which went to his original favorite's final evolution, Blastoise.
