Just hatched a shiny flawless Bagon (hence named 'Delta'), Jolly nature, 31/31/31/x/31/31, and the egg moves Dragon Rush, Dragon Dance, and Fire Fang! My shiny mega quest is nearing completion, as I only need:
Mudkip/Swampert
Meditite/Medicham
Gible/Garchomp
Slowpoke/Slowbro
Pidgey/Pidgeot
Onix/Steelix
Snorunt/Glalie
Numel/Camerupt
Carvanha/Sharpedo
Sadly, since there are less than 5 hours until I get ORAS, this Quest must continue into the new games, and there might be new hidden megas to add to this list!
