Bix, my secondary montstersona, they are a Ghazt/wubbox hybrid. They have a metal skeleton, thus they are unable to float like a normal ghazt, though they can still phase though things like fences, but will often get stuck.

They can actually change the transparency of their skin, they usually stay opaque, though they will occasionally become transparent when spacing off or when they get the absolute crap scared out of them. They usually are transparent when they fall into a deep sleep, the more transparent they are, the deeper the sleep, they are a heavy sleeper too, they've slept though Eddie bringing home multiple car batteries from the human world and him tripping over them and a few batteries hitting them square in the back of the head.

Bix has quite a few cat-like tendencies. There's a reason there aren't many things on the shelf that they can reach without parascoping and looking like an idiot and what they can reach is stuck down with museum gel, not that it stopped them from knocking down a vase of fake flowers. They will also sleep in the hallway, right in the way of foot traffic, thats how the got a couple car batteries to the back of the skull

Bix is about 8ft long from their nose to the end of their tail, much larger than the average Ghazt that on average are around 4-5ft long (the largest ever recorded ghazt is around 6ft long)
