Porygon Z

Porygon-Z is an extremely strong special attacker due to its high Special Attack and Adaptability, capable of OHKOing many key threats in 1v1 such as Zygarde, Landorus-T, and Mega Charizard X. This is also aided by its access to an extremely powerful Hyper Beam; its ability to OHKO most Pokemon eliminates the main drawback of a recharge turn. A mono-Normal typing means that Porygon-Z only has one weakness, but Fighting-types such as Mega Lopunny, Sawk, and Mega Blaziken are dominant forces in the 1v1 metagame, and it also has no resistances and only one immunity, resulting in it having a lack of defensive value. Lastly, because Porygon-Z primarily relies on its Normal-type STAB moves, it is often walled by Normal-resistant and -immune Pokemon such as Magearna and Mega Tyranitar.
