Ever wanted to catch a blue and white dragon-psychic type Pokemon who is a brother to Latias? NOW YOU CAN WITH THE HELP WITH THE NATIONAL DEX!
After beating the 4 and grabbing the National Dex, go to the DreamYard (remember it from Pokemon Black?) and climb the top of the ruins. There that blue and white dragon-psychic type Pokemon who is a sister to Latias... Oops! Did I say SISTER? I mean brother. Talk to him to hear him cry (we didn't mean to upset you, Latios) and the battle starts. Weaken him with dark and ice type moves (No ground type. That kind doesn't effect him.) and lull him off to sleep with Hypnosis. Keep throwing some Ultra Balls until he is caught.
