Legendary Pokémon
Latias is a Dragon/Psychic type Pokémon. In most games Sapphire, as a Roaming Pokémon (In Ruby, Latios will appear instead, but an event item allows you to go to an island where it is catchable. Also, there is an error in Sapphire that causes Roaming Pokémon to have lower stats than other Pokémon), Emerald (You get a choice after the Elite Four. The error was fixed in Emerald.), HeartGold (Latios appears in SoulSilver), and White 2 (Latios appears in Black 2). It has its own special item, which it shares with its counterpart. It also obtained a Mega Evolution in X and Y, but there was no way to obtain the Mega Stone needed until the next set of games. Latias has higher defensive stats than its counterpart.
