When Doduo evolves, it grows an additional head, sporting three in total. Each head has its own working brain and distinct personality, representing and expressing anger, sorrow and joy. Despite being separate, Dodrio has the innate ability to use all three of its brains to collect data, formulate and then execute complex plans and strategies. However, on occasion it may over think and analyze a situation, causing itself to be immobilized and unable to carry out any action whatsoever. Being separate individuals on the same body, the heads are well known to squabble with one another. Often they will continue to bicker until they, or at least one of the heads gets to eat. This satisfies the other two heads, quelling them and temporarily ending their infighting. Another adaption it has acquired is the ability to have at least one head alert at all times. While two are asleep, one will stand guard and look out for any approaching enemies. Extreme caution is advised when all three heads are facing separate directions. It is in this state that it is the most dangerous, and going near it may result in a severe pecking.
Along with its three heads, Dodrio has three sets of hearts and lungs as well. This allows it to efficiently oxygenate and pump blood throughout its body, thus giving it increased endurance to run vast distances without rest. It is especially prone to race vigorously across grassy plains, even in arid seasons with little rainfall.
- Tri Attack - With this mystical attack, each of Dodrio's heads casts a beam of energy. As well as inflicting damage, the Tri Attack may also inflict burning, paralysis or freezing on an enemy.
- Uproar - Dodrio goes berserk as its heads squabble among themselves. This painfully loud tantrum can inflict damage and prevent others from sleeping.
- Fury Attack - Dodrio strikes the enemy with a series of pecks.
- Jump Kick - Dodrio leaps into the air and delivers a hard kick to its enemy, causing moderate damage. Dodrio will hurt itself if the attack fails to connect.
