>>58749316The only known major organizations in the Kanto games are Team Rocket, Silph Co., the Pokémon Fan Club, and the Pokémon Trainer Fan Club. Silph's president lacks a name and the Fan Club chairman lacks a name and a unique design, both are very unlikely, so Giovanni is the only candidate.
If KANTOOOOO wasn't mentioned, I would've considered Mr. Joseph Stone of the Devon Corporation as the plot regarded to Hoenn legends and Hoenn had several Kalos references in ORAS so it would've been nice to have more Hoenn in ZA, but that wouldn't explain the Johto part.
The Japanese line seems to make this more explicit that it's Giovanni. Feel free to correct if the Google translation is wrong.
