**The Fighter NFTs**
The Fighter is represented as a NFT (Non-Fungible Token) character, a unique digital asset on the blockchain. Every Fighter comes with a unique ID, which remains permanent within the game and on-chain. Fighters have 8 different classes, each class has its own skills, abilities, and duty in the battle.
Even if you received the Fighter in the same class as your previous one, their skin, abilities, and aptitudes are randomly generated, making each character unique.
We will seed the marketplace with 2,000 [genesis fighters](/krypto-fighters/resources/achieve/fighters-rarity/genesis-fighter-benefit.md) which will all be sold in the pre-sale gacha box. That means that initially, approximately 2,000 players will be able to play the game. After that, the Fighters will be generated from the game ecosystem only. The players can mint new Fighters by using the [**Coaching**](/krypto-fighters/economy/evolve-breeding-driven.md) mechanic.
