>>50753062252 spa Charizard can 2 hit KO Mega Charizard X with no HP or Spdef evs with the moves Ancient Power and Dragon Pulse so that part at least is consistent.
Base Charizard can also tank one Dragon Claw from an Adamant Mega Zard X, which Leon's Charizard did.
Regular Zard and Mega Zard X also have the same base speed, so I guess Alain's Zard X has shitty speed, which is why Leon's Zard was able to move twice and land two hits.
Wow, I can't believe this shit actually checks out.
