The latest Mega Evolution has been revealed for Pokemon Omega Ruby and Alpha Sapphire.
Slowbro was one of the original 151 Pokemon and is one of the final evolutions of Slowpoke. It has a Shellder holding on to its tail by its teeth.
When Slowbro is given a Mega Stone in the upcoming Ruby and Sapphire remakes, the Shellder will engulf the Slowbro almost entirely, leaving only its head, arms and tail visible.
This essentially turns the Shellder into a makeshift shield for the Mega Slowbro, greatly increasing its defence stats.
Mega Slowbro also has the Shell Armor Ability, which stops opponents landing critical hits. It benefits from greatly increased Defence and Sp. Atk stats too, making it a useful teammate Pokemon in endurance battles.
Pokemon Omega Ruby and Alpha Sapphire are 3DS remakes of the GBA classics Pokemon Ruby and Sapphire, taking advantage of the new polygonal engine which debuted in Pokemon X & Y.
The Pokemon Omega Ruby and Alpha Sapphire release date is November 21 in North America and Japan, and November 28 in Europe.
