Agnol (Japanese: ゾルダンSoldan) is the last Trainer in the Deep Colosseum. Wes will receive e-mails regularly from Nett on his P★DA about him after each completed stage of the Deep Colosseum challenge until the fifth time when he finally faces him. He is the only character in the games to have the Trainer classDeep King (Japanese: ボトムキングBottom King).
Agnol's strategy revolves around using dual-types with as few weaknesses as possible. Each of his non-Shadow Pokémon had unique type combinations in Generation III. He also owns the highest-levelled Pokémon that can be fought anywhere in Story Mode, a Kingdra at Level 70.
Just like the Cipher Admins, he may be fought multiple times in the event that his Shuckle is snagged or missed. However, the Shuckle is not replaced by another Pokémon after being snagged, unlike most Shadow Pokémon.
Agnol has the appearance of a Bodybuilder, but with a unique outfit.
