You can catch Kyurem which is a very menacing looking beast, but it is also a pain to catch due to its low catch rate and powerful attacks.
It knows Glaciate (an Ice-type attack that lowers your Speed), Dragon Pulse, Imprison (to keep you from using Dragon Pulse), and then, the kicker, Endeavor. What is annoying about Endeavor is that, if you greatly weaken Kyurem, it will then set your Pokemon's HP equal to its own. Thankfully it only has 5 uses of that attack, but it still may require the use of Hyper Potions to restore your HP while you burn through those uses.
It has a fairly good amount of HP, as well as very impressive offensive stats, so don't worry about hitting it too hard; it's not going anywhere anytime soon. Fighting-, Rock-, Dragon-, and Steel-type attacks are your best bet against it for massive damage.
There's nothing it can do to heal, and unlike Thundurus and Tornadus, it will not run away from you, so it's just a matter of time before you catch it. Dusk Balls are the best type of Poke Ball you can use against it. Other than that, it is about as difficult to catch as any of the legendary trio, so expect to use up to 30 Dusk Balls on it before you catch it. It is all a matter of luck, though, so hope that you get lucky and catch it in less.
I can't explain exactly, but if you need an accurate guide to and through the chasm, go to Google and type in Marriland. He has a Pokedex with all the Pokemon's attacks and stats and locations, and he has a complete walkthrough.
To get to the Giant Chasm you'll have to get there from Route 22. But, you'll have to explore the Plasma Frigate first or else a group if Team Plasma grunts will be blocking your path. Once you beat the gym at Humilau town, you'll find the Plasma Frigate just of the coast of the seaside cave.
If you have beaten the E4, go north of Route 13and you should find the Giant Chasm.
