In 2372, Amat'igan held the rank of First and commanded the Jem'Hadar bodyguards accompanying the Female Changeling when she visited the USS Defiant to see to Odo. For security purposes, Amat'igan guided the Defiant to the new Founders' homeworld, so that Odo could face judgment by the Great Link. (DS9: "Broken Link")
Amat'igan was played by actor Andrew Hawkes.
Amat'igan is featured in the Star Trek Customizable Card Game, which describes him as a "Jem'Hadar bodyguard" for the Founders holding the rank of "Third".
