Swords of Justice: Cobalion, Terrakion, Virizion, Keldeo

Instead of releasing a duo or even two sets of them, a Legendary Quartet, for the first time ever, was released in the Unova Games. This Legendary Group was known as the Swords of Justice, consisting of Cobalion, Terrakion, Virizion, and the Mythical Pokemon Keldeo. This group was based off the of Three Muskateers, but the Pokemon Company added Keldeo as like a young apprentice. All four Pokemon have dual typing, one of which being the type of Fighting, as well as the ability of Justified.

Cobalion and Virizion are the defensive members of the group, Cobalion focused more on Defense with Virizion in Special Defense. Terrakion, however, is a physical attacking powerhouse, and Keldeo is a special attacking one. All four Pokemon are incredibly speedy too.
