Ability Detail

Steadfast is an ability in the Pokémon series that primarily grants a Speed boost to Pokémon when they flinch. Specifically, when a Pokémon with Steadfast flinches due to an opponent's move, its Speed stat increases by one stage, which can effectively turn the tide in battle by allowing the Pokémon to outspeed its opponents in subsequent turns.

Interesting facts about Steadfast include:

Introduced in Generation IV: Steadfast debuted in the Pokémon games with Generation IV (Diamond and Pearl), expanding the strategic depth of battles with its unique response to flinching.
Notable Pokémon with Steadfast: Several Pokémon can possess Steadfast, including Lucario, Gallade, and Hitmonlee. These Pokémon benefit from the Speed boost, allowing them to capitalize on their offensive capabilities once they overcome the initial flinch.
Synergy with Moves and Items: Steadfast can be particularly effective in conjunction with certain moves or items
