As a Reward for training and building upon your relationship with your Pixelmon you will be able to evolve them. For Generation 1 to evolve you will need a Pixelmon NFT and the specific serum stage (E2,E3 or E4) required to reach the next stage of evolution. During the evolution process, only the serum is burned, leaving you with two NFTs; your old and your newly evolved Pixelmon. Pixelmon evolution is possible through 2 mechanisms: Serum Burn and Pixelmon Burn.
