The Pokémon GO panel at the 2016 San Diego Comic-Con was moved into the larger Hall H as the popularity of the game created a lot of fans. Niantic CEO was at the panel discussing the game with host Chris Hardwick. During the panel, the Team Leaders were revealed. Team Valor: Candela. Team Mystic: Blanche. Team Instinct: Spark. Many in attendance were disappointed though with the lack of new details or update news and that no special Legendary Pokémon was distributed at the event panel.
