Possessing the attribute of "wind", it is one of the Warrior Ten Digimon that saved the Ancient Digital World. An Ultimate who existed only in the distant past, it has golden wings and a beautiful rainbow-colored figure. With its golden wings it sours around the vast skies, and it is said that by erecting rainbow bridges it can move freely even through the earth and sea. Ancient Irismon's beauty and abilities were given to the "Bird Man" and "Fairy" types of Digimon. Its Special Moves are generating an unending supercell (Storm Gazer), and firing a super-fused laser that shines with the seven colors (Rainbow Symphony).

“風”の属性をもつ、古代デジタルワールドを救った伝説の十闘士デジモン。遥か古代に存在した初めての究極体であり、黄金の翼と虹色の美しい容姿もつ。黄金の翼で広大な空を神速で駈け巡り、虹の橋を掛けることで、大地や水中までをも自由に動き回ることができたと云われる。エンシェントイリスモンの美しさや能力は、その後“鳥人型デジモン”や“妖精型デジモン”等へ引き継がれていった。必殺技は超巨大な暴風雨を絶え間なく発生させる『ストームゲイザー』と、七色に輝く超融解レーザーを放つ『レインボーシンフォニー』。
