Mega Gyarados is the Mega Evolution of Gyarados, a Water/Flying-type Pokémon. Mega Evolving shifts its typing to Water/Dark and sharply raises its stats for the duration of a battle.
“I suspect this Pokémon to be the true identity of a dragon written of in ancient texts, which claimed that it razed an entire village with white-hot beams from its maw.”
Mega Evolution debuted in Pokémon X & Y (2013) as a temporary, in-battle transformation. In the Pokémon TCG it appears first as “M” Pokémon-EX cards in the XY era, and again as Mega Gyarados ex cards in the Scarlet & Violet "Mega Evolution" era — both of which are among the most chased pulls of their sets.
Chase Season tracks 2 Mega Gyarados cards across 1 set, with daily market prices and Chase Index rankings. The most valuable right now is M Gyarados-EX from BREAKpoint at around $107.54.
