Personality and characteristics
Pignite, as a Tepig, has been shown to not take losing very well, often getting sad when he loses, such as in A Rival Battle for Club Champ! where he fought and lost to Trip's Tranquill. This was shown again during 's battle against Lenora, the Gym Leader of the Nacrene Gym. He fought against her and lost; he got depressed again, and did not even cheer up when Ash told him he did a good job. He also felt upset when he drew to Trip's in Ash and Trip's Third Battle!, reacting the same way he does when he loses. However, in some cases, Tepig is happy to lose, but only in unofficial training battles, as seen in A Dragon Master's Path!. Otherwise, Tepig is a rather sweet Pokémon, always looking to please Ash in battle.

Tepig has shown multiple times that he is always trying to please Ash. Lenora confirms this in Rematch at the Nacrene Gym!, where she says that Tepig is trying very hard for Ash. This could be because Tepig's former Trainer abandoned him and out of fear that Ash will do the same, tries his best to prove he is worthy. Even though abandoned by his former Trainer, he was still happy to see him again in Evolution by Fire! and also didn't feel right battling against him. After his evolution, he lost all respect for Shamus as shown when Pignite used on his former Trainer and stayed loyal to Ash.
