Ash's Donphan is one of Ash's few Pokémon that hatched from an egg.
Donphan was received as an egg in Extreme Pokémon after Ash and Bayleef won a race held by an old couple who bred and cared for numerous Pokemon eggs.
The egg later hatched into Donphan as a Phanpy in Hatching A Plan and was a playful Pokemon yet refused to obey Ash's commands. Unfortunately, things took a turn for the worst when Team Rocket arrived to capture Pikachu. In the process, Phanpy was shocked by Pikachu's ThunderShock despite Ground-types being immune to all kinds of Electric attacks. Despite this, its trust for Ash was destroyed and the second it got hit and heartbroken, it ran away, leaving Ash, Brock, Misty and Pikachu searching for it.
Phanpy fell into Team Rocket's clutches who manipulated the little baby Pokemon into thinking they actually cared for it but once Pikachu had been captured, Team Rocket showed their true colors and dumped Phanpy in the cage with Pikachu.
Luckily, though, Pikachu, having seen through Team Rocket's scheme hatched an escape plan and the two managed to get away although Phanpy was swept away after falling into a river. Ash saved the little Pokemon and regained its trust for him, realizing that he cared more about its well-being than Team Rocket ever would. Phanpy later grew to resent Team Rocket and used Rollout to weaken the enemy's Pokemon before Pikachu used Thunderbolt to send the bad guys blasting off again. After that, Phanpy and Ash formed a strong bond that continues to this day.
Phanpy was unable to replicate this success in the next episode where Team Rocket used their new Delibird who launched a Blizzard which managed to knock out Phanpy in a single blow due to the fact that Ground-type Pokemon are weak against Ice-type attacks.
In As Cold as Pryce, Ash, arrogantly misjudged the situation and sent Phanpy out to fight Pryce's Dewgong but due to Dewgong holding the type advantage, Phanpy lost and was encased in ice as a result.
In Reversing the Charges!, Phanpy solely fought against Team Rocket and one of their many mecha machines but could not beat it. However, just when it looked hopeless, Phanpy evolved into Donphan and learned Hyper Beam before using it to defeat Team Rocket.
Ash used Donphan in the battle against Pike Queen Lucy and defeated her Seviper, before getting knocked out by her Milotic.
Donphan returned to Ash in the Sinnoh League where it lost to Conway's Dusknoir.
Donphan is set to reappear along with all of Ash's Pokemon in an upcoming episode of Best Wishes Season 2.
