Template:Nihongo is a Darkloid created by Dr. Regal that appears in all versions of MegaMan Battle Network 5 and was defeated. It is believed he is based off PlanetMan.EXE.Cosmoman has no original counterpart.
In MMBN5, he is the boss of the Fifth Liberation Mission which is in End Area. He is defeated but is revived later. After MegaMan.EXE defats his team leader, CosmoMan will take him away before he breaks the dark power's hold on him. He reappears and is deleted again in Nebula's base.
- Cosmo Ring: He throws a ring that hits a glowing 2x2 space. Simply move out of the glowing area to dodge.
- Cosmo Buster: He summons three planets and sends them at you. Each one takes up 3 adjacent rows. To dodge, destroy the rings around them by attacking the planets, making it easier to dodge.
- Cosmo Gate: CosmoMan blocks an attack firing forward at him, and then drops a meteor at the player, hitting in a + fashion.
- Cosmo Planet: He disappears into a space warp and sends multitudes of small planets at you fast. It is very hard to dodge. You can use an Invisible chip is you have one or you can try to attack CosmoMan which will knock him out of the space warp and halt his attack. A Guard chip or the Shield program would be ideal for this task.
