Pokémon Omega Ruby and Alpha Sapphire get some interesting new screenshots today that show off a large red gem unique to Sableye’s Mega Form.
As seen in the screens, Sableye visibly holds the gem up in battle, which appears when it Mega Evolves. In this state, it greatly increases Sableye’s defense and special attack at the cost of speed. It also gets the ability Magic Mirror, which deflects any non-damaging moves (Thunder Wave, Stealth Rock, Fake Tears, etc.) back at the opponent.
The gem itself is said to have been separated from the body of a giant and it clearly causes Sableye’s eyes to glow red instead of its normal blue color. You can view all the screens below.
