Hidden Ability: Guilt Trip

When Flutterby's HP falls below 50%, its Guilt Trip ability activates. For the next 5 turns, Flutterby is unable to attack. This is represented in-game by a visual effect, such as a shimmering aura around the Pokémon, and a message indicating the effect. This reflects its inherently kind nature, making it unable to fight when it feels it has caused harm. The inability to attack is a significant drawback, but it could be strategically used to force a switch or to avoid further damage. The effect ends after 5 turns or when Flutterby's HP is restored above 50%.
