Garamon is a Kaiju from Ultra Q. It first appeared in episode 13 "Garadama", and returned in episode 16 "Garamon Strikes Back". The robot monster is perhaps the most recognizable monster from Ultra Q, and is among the Kaiju most associated with the landmark series.
A strange meteor emitting electric waves was discovered in the Japanese countryside. Soon after its discovery, a larger "Garadama" meteorite crash lands in the center of a large lake, destroying a local town and drying up the body of water completely. Soon only the strange meteorite was visible in the dry lakebed, and it didn't take long for Garamon to emerge from within. Emitting a strange clanking noise as it walked, the odd monster proceeded to scout out the area. It then made its way towards the dam and quickly charged right through it, destroying the barrier that separated it from populated areas. However, before the monster could progress further in its attack, the secret of the smaller Garadama meteorite was finally unlocked: the strange rock actually served as an electronic brain for Garamon, and the radio waves it emitted were controlling the monster.
