The Miclus (ミクラス mikurasu) is Seibu Kaihatsu's mascot. It served roles in Seibu's library of games as a boss enemy, collectible items, and game secrets. Its most notable role is as a secret playable character in Raiden Fighters 2: Operation Hell Dive and Raiden Fighters Jet.
The Miclus fulfills the same role in Xeno Fighters R as it did in the Raiden Fighters series. Stages have quite a few of them hidden from view, and they can be revealed by hovering over their hiding spot. Micluses will yield a medal for each shot until the Miclus explodes, granting the player 100,000 points.
