Keibi Machines (警備マシンズ, Keibi Mashinzu, lit. Security Guard Machines), simply also known as Machines (マシンズ, Mashinzu),
is a game exclusive team introduced in Inazuma Eleven 2: Kyoui no Shinryakusha. They, however, made a brief cameo in the Inazuma Eleven anime in episode 60.
In episode 60, Seijirou overhears intruders at Aliea Gakuen and orders Keibi Machines to catch them. Once they found the intruders, they got it a soccer battle with them. They were, however, destroyed by Domon, Kidou and Gouenji's kicks. Later, in the same episode, one of them briefly appears already destroyed, seemingly, by Onigawara before he and his colleagues step onto the Aliea Meteorite Room.
