Some guy in the Memorial Pillar on Five island ( You need the Rainbow Pass ) has an Onix who died named Tectonix.
No because Crystal and Leafgreen are not compatible regardless if its on the VBA.
Onix evolves into Steelix when it is holding a Metal Coat and traded to someone else.
Sadly you can't. You can trade From Yellow to : Red, Blue, Green, Gold, Silver and Crystal. From LeafGreen you can trade to : FireRed, Ruby, Saphire and Emerald.
Onix is in Pewter City where Brock is.

Sorry, but you cannot catch Crystal Onix in Pokemon Silver. And don't try to go out on eBay or something to get Pokemon Gold because he's not in that game either. Crystal Onix was only in the anime episode: The Crystal Onix. Anyone who says you can get it like on youtube either hacked the games or made their own games, which is copyright.
