10 Rare Pokémon You Only Had ONE CHANCE To Catch
5. Steven's Shiny Beldum - Pokémon Omega Ruby And Alpha Sapphire
Now I know a lot of you might be saying "Hang on a minute, a Beldum isn't exactly a rare Pokémon, nor is it that hard to get Steven's variant either, as you can trade with him in-game".
Well, hang on a minute.
It's the SHINY version of Steven's Beldum that is incredibly rare, seeing as this was a timed exclusive Pokémon only issued on the release of Omega Ruby and Alpha Sapphire.
Even getting a shiny variant of the original Beldum is an utter chore, what with the random nature of these things and the excessive breeding you'd need to do, so being able to skip all that faff AND get a nice nod to prior adventures with Steven's Beldum makes it all the better.
Plus it comes with a Classic Ribbon AND is holding a Metagrossite, meaning you could Mega Evolve your new friend into an absolute beast.
If you did want to get your hands on this variant however, you'd have to have been pretty quick off the mark, as the promotional window for claiming it was only a few months after launch.
