Agnol

Agnol is the last battle in the Deep Colosseum Challenge. You receive e-mails regularly about him after each completed Deep Colosseum challenge from Nett until the fifth time, when you finally face him.

Agnol's nickname is the Deep King. This suggests that he is the King of the Deep Colosseum.

Agnol's team consists of a lv. 68 Skarmory, a lv. 68 Girafarig, a lv. 69 Sableye, a lv. 68 Shedinja, a lv. 70 Kingdra, and the second-to-last Shadow pokemon, a lv. 45 Shuckle.

Skarmory lv. 68 (Sturdy) Steel Wing Return Sand-Attack Drill Peck

Girafarig lv. 68 (Early Bird) Return Psychic Light Screen Thunderbolt

Sableye lv. 69 (Keen Eye) Faint Attack Shadow Ball Aerial Ace Confuse Ray

Kingdra lv. 70 (Swift Swim) Hydro Pump Dragonbreath Ice Beam Attract

Shedinja lv. 68 (Wonder Guard) Silver Wind Confuse Ray Shadow Ball Dig

Deep King Agnol's strategy revolves around using dual-types with as few weaknesses as possible. Just like the Cipher Admins, he may be faced multiple times in the event that the Shuckle is snagged or missed. However the Shuckle is not replaced by another pokemon after being snagged like most previous Shadow Pokemon.

Assuming Shuckle is the final capture and you've collected all 46 prior Shadow Pokemon, defeating Agnol will unlock the final battle against a criminal using a Shadow Togetic to attack civilians, who TV reports believe to be Wes.
