Pignite, as a Tepig, is shown as a friendly and courageous Pokemon much like his trainer. He is also shown to be a powerful Pokemon with a lot of balanced potential, speedy reflexes, and a strong battle strengths which allow it to defeat many impossibly strong opponents.

As Tepig
Pignite first appeared as a Tepig in The Starter Choice!, when he was released out of his Pokeball to fight with Oshawott. But when he was thrown by Water Gun, he was rescued by Nate who showed him true friendship and was chosen as his starter Pokemon. He later battled against Hugh's Oshawott in the next chapter, but fainted simultaneously alongside it.

Later in Enter Rosa and Snivy!, he fought against a wild Pidove where he uses his powerful skills and speedy reflexes to defeat it and allowing his trainer to capture it. In BF004, he then battled Benga's Larvesta where he was able to defeat it with a powerful Flame Charge.

In BF007, he fought against Cheren's Herdier where he had an advantage with his opponent at first. But when he was almost out of breath, he activated his ability Blaze which enhanced his reflexes, skills, and Flame Charge attack, with a finishing Rock Smash to defeat the Loyal Dog Pokemon.

In BF010, he fought with his rival again where it was shown that Hugh's Oshawott had enhanced its reflexes and outmatched him easily by utilizing Aqua Jet and then is defeated by Razor Shell.

As Pignite
In Defeating Roxie!, he was the last Pokemon to be used during the Virbank Gym battle with Roxie. After getting knocked out and crushed by Garbodor's powerful Poison-type attacks, he evolved into Pignite and used Flamethrower to burn it and finished it off with a powerful Flame Charge-Flamethrower combination.
