The Drought Kyogre post was a joke to a Charizard in Ubers discussion on Showdown. People were comparing Charizard to Reshiam as to what would damage Kyogre better in the sun, and it was eventually figured out that Charizard did a small amount of damage that Reshiam couldn't do. Therefore, it was decided that Charizard was the best Fire-type counter to Drought Kyogre. Yes, the entire conversation was a joke.
