Drift Away

Drifblim's Pokedex

Drifblim I think less is revealed about Drifblim than we learn about Drifloon from reading Pokedex entries. Drifblim's Pokedex entries are certainly less dark. That doesnít make it much better of a Pokemon, though. People still go missing. There is still darkness and intrigue surrounding the Pokemon.

Game
Pokedex Entry
Diamond
It's drowzy in daytime, but flies off in the evening in big groups. No one knows where they go.
Pearl
It carries people and Pokemon when it flies. But since it only drifts, it can end up anywhere.
Platinum
At dusk, swarms of them are carried aloft on winds. When noticed, they suddenly vanish.
HeartGold
SoulSilver
It can generate and release gas within its body. That's how it can control the altitude of its drift.
Black
White
At dusk, swarms of them are carried aloft on winds. When noticed, they suddenly vanish.
Black 2
White 2
They carry people and Pokemon, but the wind can catch them, so there can't be a fixed destination.
X
It carries people and Pokemon when it flies. But since it only drifts, it can end up anywhere.
Y
It's drowsy in daytime, but flies off in the evening in big groups. No one knows where they go.
Omega Ruby
It carries people and Pokemon when it flies. But since it only drifts, it can end up anywhere.
Alpha Sapphire
Itís drowsy in daytime, but flies off in the evening in big groups. No one knows where they go.
Sun
There was once an incident in which a man took a trip riding a Drifblim, only to go missing.
Moon
Even while under careful observation, large flocks of Drifblim flying at dusk will inexplicably disappear from view.

I like to look at Drifloon and Drifblim together as one Pokemon. When looking at Drifblim as an extension of Drifloon, and taking everything Drifloon's Pokedex entries teach us about the Pokemon, Drifblim's entries make a lot more sense. Maybe since it's larger, it doesn't just target children anymore. Maybe it attempts to take anyone or any Pokemon it can get to ride it to the afterlife.

Drifblim's tendency to travel in groups, and its ability to disappear when watched may be a result of its evolution. Perhaps Drifloon gets smarter, stronger, and more adaptable when it evolves.
