While chocobos tend to be peaceful, they will defend themselves violently if they feel threatened, lashing out with beak and claw. Generally, a chocobo will attack with one of its claws and run for safety, but if it sustains a large amount of injury, they will use their Chcobuckle ability, then run. Again, a chocobo's first instinct in combat is to run. In combat with allies, a chocobo will heal the better attackers to it does not have to engage in combat itself.

Flapping its wings furiously to work the muscles around its stomach and esophagus, a light blue chocobo can belch a super-cooled piece of ice, dealing cold damage to the target of its ranged touch attack. This is a full attack action that provokes attacks of opportunity. This attack deals 2d8 plus half the chocobo's HD in cold damage on a successful hit. A light blue chocobo is unharmed by its own Choco Frost. This attack is treated as an exceptional projectile weapon and has a range increment of 10 ft.

When a chocobo feels threatened for its life, it will lash out viciously in a flurry of attacks. It takes a -2 penalty on all attacks that round, but uses a standard attack action to attack a number of times equal to the number of attacks allowed by its base attack bonus, but all of those attack are at full attack bonus (including the -2 penalty). These attacks may use any combination of claws and beak and all deal 2d8 damage plus one and a half times the chocobo's strength. It usually uses its move action that round to run from battle.

Chocobo's are great at jumping, using their strong legs and wings to optimal effect. Because of this, chocobos gain a bonus on jump checks equal to one third of their HD.

A chocobo is treated as having the Run feat. Chocobo's strong, tough legs, and gripping, scaled feet are prefect for traveling. A chocobo can travel without penalty over any solid, non-damaging surface without needing to make a balance or tumble check. Also, a Chocobo can sprint for short periods of time. It may move at twice its base land speed for one round every five minutes. This stacks with the effect of the Run feat, allowing a chocobo to move 480 feet in a single round.

A chocobo cannot fly, despite its wings. They serve only to assist in balance while running and support while jumping.

In shadowy or bright illumination, a chocobo can see twice as far as a normal human.

Light blue chocobo have the amazing ability to run over shallow bodies of water, including rivers, lakes, and water just off the shore. This is due to the adaptation of their bone to become spongy and hollow, while their skin, feathers, and hard legs and beak still protect their body just as well from attacks. Unfortunately, a light blue chocobo can only run over shallow water, not stand on it; the chocobo must remain moving to not sink.
