Yes, Cobalion is a legendary pokemon.
you first catch/defeat a coballion (mistralon cave), and then look around pinwheel forest
if you have Terakion, Coballion and Varizion then you need to have an event then go to the moor of Icarus and you will find Keldeo.
Coballion is a rare Steel and Fighting type that can be found east of a house near Chargestone Cave. Surf there and look for an old man, and then look for Coballion.
In the topmost floor of Mistralton cave (bring Pokemon that know Flash and Strength)
the best would be zekrom because legends have good stats if he is gone then i would recommend catching coballion at milastraiton cave
well i don't remember the levels of the Pokemon but i used a conkeldurr, a unfezant, a samurott, a victiny,a coballion, and reshirom and it was fairly easy
You will need an event witch has only came out in japan or some other country but not in north america, if you want to teach your keldeo *somthing* blade witch is a good attack, no not leaf blade. You need to go to the moor of icarus with keldeo, terakion, coballion and varizion in your party and terakion varizion and coballion will teach keldeo *something* blade.
You find Coballion in a cave east of Chargestone Cave, get there by surfing, inside look for an old man, speak to him and look in the cave for Coballion. Once you find Coballion, you can find Virizion in Pinwheel Forest(Surf and Cut to it), and Terrakion in Victory Road. In Black/White you no matter what get Reshiram/Zekrom. If you import a special-event Shiny Raikou/Entei/Suicune or Celebei... you can find Zoroark in Lostlorn Forest and bring your special-event Shiny Raikou/Entei/Suicune to the trailer. If you bring the Celebei to an empty building with a woman and a boy together, the boy is Zorua. To find a Wild Volcarona, go to the Desert Castle where you met Ghetis there looking for the White/Black stone, take a right and go up from there an find a hole. Navigate through their for a LV 70 Volcarona. And you get a Victini by bringing a WI-FI Mystery Gift (Available until April 30) the Liberty Pass to a ship in Castelia city. You can still not receive Genesect, Melodia, and a few other Event Pokemon
