Gold Bowser Statue
From the Super Mario Wiki
Super Mario World
Gold Bowser Statues in Super Mario World are found in door 7 in Bowser's Castle. Instead of shooting fireballs, they jump toward Mario or Luigi, and unlike the gray statues, the gold ones can damage the brothers by direct contact. The only way to defeat it is to lure it into a lava pit. Their immobile counterparts are the Gray Bowser Statues.
Super Mario Advance 4: Super Mario Bros. 3
Gold Bowser Statues also appear in a World-e level, Bowser's Last Stand, in Super Mario Advance 4: Super Mario Bros. 3, with the same appearance as those of Super Mario World. They are found in the second-to-last room before the Bowser battle alongside regular Gray Bowser Statues.
Super Mario Odyssey
In Super Mario Odyssey, various golden Bowser Statues are seen in Bowser's Kingdom. Two of them appear in the area that Topper and Hariet are battled, with one being destroyed for each defeated. They have clothes based off of the Japanese gods Raijin and Fūjin, the gods of thunder and wind, respectively.
Heads of golden Bowser Statues can be found in some parts of the Kingdom as well. Cappy can be spun on both of their horns for coins. Two large heads appear facing inward on a large arch towards the end of the poison-filled area at the top, and do nothing. Four large heads appear on the giant arch before the RoboBrood arena, where they let out flame every few seconds. However, since they are in the corners and are facing outwards, getting damaged by them requires jumping off of the structure. A much larger head appears on the front of the same arch, and has a Power Moon in the nose that can be obtained by Ground Pounding on it.
