One of the most exciting aspects of Pokemon Legends: Z-A taking players back to the Kalos Region is the return of Mega Evolutions. Many fans have been hoping to see Mega Evolutions return to the series in some capacity after their removal from Gen 8 onward, and Pokemon Legends: Z-A will finally give these fans their wish. While the return of Mega Evolution has created a lot of room for fans to speculate on which critters might receive new forms, there is one Gen 1 monster that deserves a Mega Evolution after missing out on getting a new form in the past few generations.
