Big Brother Mentor: Brock acts as one for Red. After witnessing Red lost his first Pokémon Battle to Blue, Brock came to Red and encourages him to go the Pewter Gym to improve himself there. During their Gym Battle, Brock lectures Red the importance of skill, strategy, and bond of the trainer and his Pokémon.
Corrupt Corporate Executive: Naturally to be expected from the boss of a criminal organization. Much of Giovanni's plans involve poaching Pokémon, using Pokémon for experiments, and taking another company hostage just to obtain new technology all in the name of making profits for his business. He even refers Pokémon as just "business" and doesn't understand why Red would see them as something more until he rediscovers his old passion during the final Gym Battle.
Hidden Depths: His gym battle with Red slowly, but surely, brings out his dormant Hot-Blooded nature and passion for Pokemon training that he had forgotten for years.
Heel-Face Turn: Preforms one after his battle with Red, realizing Red's view of Pokémon as more than tools to commit crimes is right.
Lack of Empathy: Giovanni shows no emotions when Red asks why would he harm Pokémon, simply saying that Pokémon means business and that it requires a little sacrifice to maintain that business. Subverted in his Gym Battle when Giovanni realizes he's empathizing with Red's determination and passion.
