Deino is the big new one here, mostly because of the National Pokédex more than anything. He makes a nice Special-attacking Dragon Pokémon, though he can be a bit slow and has a huge weakness to Fairy. Despite that, he’s useful for the main game as Fairy Pokémon are infrequent at best.
Granted, your Mega Latios/Latias is superior, but if you prefer something else… Bagon is also a good Pokémon when evolved into Salamence; Mega-Salamence will be a nasty Pokémon to fight with in general, possessing great Speed and mixed-attacking capabilities.
Again, your Lati is preferable, but if it’s neglected, you may as well.
Fly here and enter!
When you arrive, approach the big waterfall. (Come on, you can’t miss it.) Use Waterfall to get up that bad boy, then go east and land on the small chunk of land there. Use the Dowsing Machine to find the Stardust hidden there, then go northwest and through the archway.
Go east and north along the lake shore to find a Dragon Tamer. Descend the ladder nearby.
Defeat the Battle Girl running around to the southwest, then go west and north to battle the Dragon Tamer, then ascend the ladder further north.
Battle the couple to the east, then go up the steppes to the north. Descend the ledges further to the east, hanging along the west side. Turn on your Dowsing Machine as you go down, too; as you do, look carefully when the small stalagmites begin to pop up.
A sparkly area should be nearby, signifying some Aerodactylite . Examine the same spot once more to find a hidden Super Repel . Go down another ledge or two, then southwest and down the ladder.
Here, get Surfin’ and head north, east, and then far to the south to the southeast corner. Go through the doorway here to the entrance area where you can find a PP Max.
Return to the previous area and go to its north-central portion. Head to the northwest part of this area and you can use the Dowsing Machine to locate a Star Piece ; from there, go east and through the archway.
In this room, you’ll be able to find Bagon , and it’s literally the only place in the game to find him. Don’t forget TM02 (Dragon Claw) at the north side of the cave; Dragon Claw is pretty much a standard move on any Physical Dragon Pokémon. In any case, you’re done here for now.
