Personality and Characteristics
Charizard is an incredibly aggressive Pokémon, going as far as attacking his own Trainer if feeling angry or displeasured. His aggressiveness only increases during battles, which also proves to be a major weakness, as Charizard refuses to utilize strategy, and solely relies on brute strength.
