Pit's first and currently only animated appearance is in the animated television series, Captain N: The Game Master.
He is a main character here, and he's followed by his enemy, the Eggplant Wizard. In this series, however, we know him as Kid Icarus. His homeland is also different, being Mount Icarus.
Although he isn't very powerful in this series, he does boast courage. He is also the only member to fly. But most memorable about him is his affection of adding 'icus' to the end of most of his sentances.

In appearance, he has a cream toga, white gloves and sandals. His hair is red, and usually covers one of his eyes. He also carries a set of arrows with him, which can dematerialize foes. Other special arrows are also hidden away here. He is still short in stature, and often dislikes this. By season 3, he changed a little in order to look more like his GameBoy sequel self.

Kid Icarus was a regular character in the series, but there are many differences to how he is today.

Kid Icarus can fly, yet in Smash Bros Brawl, Pit cannot normally fly

Kid Icarus isn't very powerful, yet Pit is

And the obvious change in design
