Dodrio first appeared was in Pokémon, I Choose You!, were it has a brief appearence, while shouting its cry to the rising sun like a rooster. Its next appearance was in The Flame Pokémon-athon. Dario used the three-headed bird to compete in a race, but was beaten by Ash who was riding Lara Laramie's Ponyta.
Dodrio also made a cameo in A Chansey Operation. This Dodrio had its necks tied in a knot.
Watch out if Dodrio's three heads are looking in three separate directions. It's a sure sign that it is on its guard. Don't go near this Pokémon if it's being wary - it may decide to peck you.
Apparently, the heads aren't the only parts of the body that Dodrio has three of. It has three sets of hearts and lungs as well, so it is capable of running long distances without rest.
It has also been widely debated that if Dodrio has wings or not, seeing as Doduo's wings are mentioned in the Yellow Pokédex entry
Origin
Despite its name, it seems like it has more in common with ostriches than dodos.
Name origin
Dodrio's name seems to be a combination of dodo, an extinct, flightless, bird, and trio, meaning a group of three. The dori in its Japanese name may also come from 鳥 tori, bird, or it may be a combnation of ドードー dodo and トリオ trio because of its three heads.
