Dakim is not stupid, but he's not a very intelligent man. He usually tries to keep his cool, yet he can become very dangerous when angered. Dakim is the only Cipher Admin not directly involved in the creation and distribution of Shadow Pokémon. Instead, he and his underlings appear to be used as general enforcers and muscle. He has incredible physical strength, and he'll physically attack any victim who won't give in to his demands. He also has surprisingly good jumping abilities, as he flees with a powerful leap.
Ein dispatches Dakim to Mt. Battle to steal the Time Flute so that Celebi cannot be summoned. Dakim and nine of his underlings take over the first area of Mt. Battle, and Dakim tries to intimidate the Area Leader, Vander, into surrendering the mystical instrument. Dakim strikes Vander after he fails to convince him to just surrender the Time Flute.
Wes and Rui show up and managed to defeat Dakim and all of his minions. Even the might of Dakim's legendary Pokémon Entei can not overcome Wes, which gets snagged in the process. Dakim later reappears at Realgam Tower, guarding one of the four keys that will allow Wes and Rui access to the tower's main floors. Dakim is defeated here as well and yields the Green ID Card to Wes. After the battle Dakim remarks that throughout his entire life he has only lost to two people - Wes and Master Nascour.
Dakim is encountered one last time in the Deep Colosseum.
