Junk Golem

Junk Golem (ジャンクゴーレム) is, as its name implies, a robot made of junk. Dr. Wily created it in a hurry when he discovered Mega Man was inside his fortress. Junk Golems appears only in the fourth Wily Castle stage in Mega Man 3, and also is the only enemy there (other than the rematch against the Robot Masters in the teleporters). They throw junk blocks at Mega Man.

Strangely, if the Junk Golem is destroyed as a junk block falls, the junk block will still be hurled even though there is nothing there to throw it.

They also appear in Hyper Storm H's Stage in Mega Man: The Wily Wars.

Flashing out the most basic of frames with chunks of junk is how the Junk Golem was created. Through he may seem like a "rush job" as far as robots are concerned, the many layers of junk that make up his external armor make it difficult to get a critical hit on him. Junk Golem does not have any built-in weapons at his disposal, but his powerful physical strength makes anything within his reach a dangerous weapon.

In "Power Battle", after the defeat of his Sniper Joes, Dr. Wily reveals an upgraded Junk Golem to help him defeat Mega Man, but Bass tells him to get lost and blasts the Junk Golem.

Rockman: Yomigaeru Blues
Junk Golem had a short appearance alongside Mecha Dragon and Yellow Devil MK-II as part of the defenses from the Wily Patrol headquarters.
