Guru Guru was the 56th Saucer Beast who saw action, quite briefly, at the end of Episode 52 of UFO Robot Grendizer and was the final Saucer Beast of the show - the Saucer Beast line to be replace by Dantus' Vega Beasts, monsters which did NOT possess the Saucer Mode. With the exception of its demise, the Summary of the actions taken by it will be posted on the King Gori Bio, as this is a two part episode. Here I will only provide the general appearance and abilities of the Monster.

Its vehicle form was the standard disk, Shells were lavender in color with a pink outline in the middle; spikes ran around the middle section. The Monster form was a quadruped, using the saucer form as main body; had a red feline face, with three horns, long fangs and yellow legs. Its only abilities were Vega laser beams from its eyes and firing missile from the mouth.

Guru Guru was destroyed at the hands of King Gori, in a desperate challenge by Zuril to demonstrate the skill of his Saucer Beasts, but its end marked their Swansong.
