thought he was ghost/ground, not to mention his name references golems.
He also looks like Big O, uses the mecha-standard Rocket Punch that essentially dates back to Mazinger Z (with not only massive numbers of punching moves, but also an ability that boosts punches further, no less), and flies with rockets. And for good measure, its Japanese name Goloog is not only a portmaneau of Golem and Cyborg, it's also very reminiscent of the Gelgoog from MS Gundam's UC series. Typing isn't everything.
All above is completely true and accurate, unless it isn't.
