Melli believes the power granted by Frenzying is a blessing granted by almighty Sinnoh to protect the Diamond Clan. He has an arrogant and self-centered personality, but according to Mai, he used to be very shy and withdrawn, until he one day announced that he would work hard to help Adaman.
Melli first appears during the meeting between Adaman, Kamado, and the player when discussing the situation involving the Diamond Lord Pokémon, Electrode. He storms into the room demanding to be involved since he is the Warden responsible for Electrode.
Once in the Coronet Highlands, Melli attempts to sabotage the player by removing the torches within Wayward Cave, and then challenging the player to a battle outside the Ancient Quarry. Once at the Moonview Arena where Electrode resides, Melli challenges the player once again to protect Electrode from being calmed.
In the post-game, Melli can be found at Moonview Arena. Speaking to him allows the player to initiate a rematch against Lord Electrode. If the player completes the challenge, Melli will award four Exp. Candies M and, if the player received no damage, three Grit Pebbles.
