Pokémon - At last! It is finally complete!

Professor Oak the true villain? It would appear so…

until you realize that there is one more team.
Team Flare.

With this added, we can see that the true message is 'F Gramps'.

There's only one person who would say this. Therefore, the true villain is not Professor Oak, but GARY MOTHERFUCKING OAK!

Thus more proof that Team Flare was a mistake.
