This Noivern is a Dragon-type Pokémon owned by Ash Ketchum. It is one of Ash's few Pokémon that hatched from an egg and is the fifth Pokémon he caught in the Kalos region as well as the fourth in his current Kalos party./
After hatching from an egg, Noivern, as a Noibat, was an inexperienced flier and a bit of a crybaby when he gets stressed and upset. However, he does wish to fly. Noivern seems to have an affection for Ash, as he was the only one to calm him down when he cried. This is because he was the first person Noivern saw after hatching. Noivern also seems to admire Ash's Hawlucha very much and looks up to him as a big brother figure much like the relationship between Iris' Axew and Ash's Scraggy, both being part Dragon type and Fighting type. Noivern also has the same relationship with Talonflame and he enjoys flying around with it. Noivern appears to have the ability to use ultrasonic waves to help him decide if the fruit is bad or good and locate someone in dark places. Noivern appears to like Ash, seeing him as a parent figure, as such Noivern seems to want Ash's approval and to make him proud. As time went by, Noivern grew bigger and stronger, often helping Ash with finding various things with its ultrasonic waves as well as battling. Since evolving, Noivern is stronger than ever and is more willing to go up against formidable foes like Zapdos or Salamence. Noivern also became more willing to protect those who are close to him. For instance, when Zapdos knocked Hawlucha out of the sky, Noivern rushed to his rescue and when Lysandre's Shiny Mega Gyarados was about to hit Pikachu with Dragon Tail, he pushed Pikachu away to let him get hit instead.
As an egg
An egg was found by Hawlucha, who was training and was given to Ash. Ash, Hawlucha, Pikachu, Bonnie, Dedenne, Pancham, Chespin and Talonflame, as a Fletchinder, warmed the egg together. Due to Talonflame's Flame Body, the egg hatched into a Noibat.
When Noibat open his eyes he first saw Ash then introduce himself and Pikachu to him others do as well. Noibat was then scared by everyone surrounding him and lets out a powerful Supersonic screech as he cried. However, he was quickly calmed down by Ash. After eating some fruit and drinking some water, Noibat attempted to fly but couldn't keep up in the air even with help from Ash's Hawlucha and Fletchinder. Noibat, along with Hawlucha, was then kidnapped by Team Rocket. After Hawlucha freed him, they both retreated to a nearby cave and evaded Team Rocket. After reuniting with Ash and his friends, Noibat decided to join Ash's team not wanting to leave him and his new friends, especially Hawlucha sparking their new found relationship and friendship, and Ash gladly caught him.
Later, Noibat was used to help Ash compete in the Pokémon Sky Relay competition. But even though he lost the tournament from Orson's Starly in a small margin, he successfully learned how to fly and made Ash, Hawlucha, Fletchinder and all of his friends proud.
Since he has learned how to fly, Ash has used Noibat more frequently, such as helping to find the right direction in dark caves, where to find moss for medicine making and to join Talonflame in searching for lost Pokémon, including finding Clemont's Chespin and Bunnelby, a Tyrunt who was stolen and evolved into Tyrantrum, an Eevee who ran off from the gang, his trainer after he wandered off into the Winding Woods when he was defeated by Wulfric from his recent gym battle, and a Carbink who keeps wondering off.
When Squishy ran off, Ash used Noibat while teaming up with Clemont's Luxray using both Supersonic and Eyesight to find the way while they continue to find Squishy. While fighting Team Flare, it reveals that Noibat knows Tackle but was knock off from Bryony's Bisharp's Iron Head. Noibat later teams up with Greninja and Pikachu along with Serena's Braixen and Clemont's Luxray against Team Flare and their Pokémon before being defeated by Zygarde in its 10% form. 
In A Windswept Encounter!, Noibat had to deal with a Breloom, after he accidentally bumped into it. This caused Breloom to get angry and used Poison Powder on Noibat, poisoning him completely. However, a wild Floette showed up and healed Noibat with Aromatherapy. When Floette and Breloom were captured by Team Rocket, he managed to track them down and free the captives with its newly learned move, Acrobatics.
Noibat was later released by Ash to use Supersonic to lead them through the cave and its directions of finding a different pathway. Noibat was later rescued by Hawlucha from a collapsed debris due to the attack made by the Legendary Pokémon, Zapdos as it created thunderstorms out of anger and also the one who attacks Team Rocket in mid-air using Thunder while trying to avoid being captured. The collapsed debris also separates Ash, Pikachu, Hawlucha and Noibat as Ash encourages Noibat that they were together even Pikachu and Hawlucha also agreed to his word making Noibat happy. Ash and his Pokémon continued on and Noibat is the one who gets the correct pathway using Supersonic. They were finally confronted by Zapdos who uses Thunderbolt to stop them on their tracks as they also saw Team Rocket who are revealed to be hiding. Noibat also grins at Meowth after revealing to Ash and the others about their usual tactic to capture Pokémon. Ash finally decides to ask Zapdos about what happened but it fails when Zapdos keeps attacking them forcing him to release Talonflame to distract it as both fight in an aerial battle making Ash, Pikachu, Noibat and Hawlucha to run quickly. Talonflame was soon knocked out as Ash recalled it. Noibat decides to watch Hawlucha to fight Zapdos while Ash and Pikachu continues to run. But Ash saw it watching the battle as Hawlucha told it to go with Ash after he knocked Zapdos with a single High Jump Kick. However, when Zapdos blasts Hawlucha with its Thunder as he starts falling into the ravine, Noibat desperately flew to Hawlucha as fast as he could, evolving into Noivern in the process much to Hawlucha's surprise before it loses consciousness.
After saving Hawlucha, Noivern battled Zapdos while dodging most of its Thunder attacks and counters it with its newly learned, Boomburst. Due to Ash's strategy, Noivern uses the advantage by using the terrain to hide from Zapdos to make a sneak attack as the strategy proved to be successful. Noivern reappeared from behind and ambushes Zapdos using Boomburst to knock it off into the terrain.
However, when Zapdos was falling into the edge after the damage it took from Noivern's Boomburst, Team Rocket reappeared and successfully capture Zapdos causing Ash to get mad at their actions. Noivern and Pikachu blasted Team Rocket off with both Boomburst and Thunderbolt combination as it also rescue Zapdos from captivity by breaking the bound using Acrobatics. Afterwards, Zapdos was successfully calmed down and, impressed by Noivern's strength, power, bravery, and compassion, stopped the thunderstorms. Hawlucha was also impressed on Noivern's bravery, effort and success as both are seen doing a fistbump. Once Ash reunited with his friends in Joule Town, Noivern was seen sitting in a tree, eating some fruit after a hard day's work before the start of the Zapdos Festival.
Noivern was later used to battle against Alain and his Metang when Ash let his Greninja along with Clemont's Luxray be fully healed at the Pokémon Center. Although he did a huge amount of damage during the battle, Noivern was outmatched by Metang's power as they collided with both of their Acrobatics and Metal Claw, he was easily defeated due to Metang's high endurance. But despite his lost, Ash thanked him for trying his best in his first Pokémon battle. Noivern was last seen being released by Ash along with Hawlucha and Talonflame to make Ash and his Greninja to practice sprinting. 
Noivern was used as the first Pokémon in a three-on-three battle against Sawyer in A Full-Strength Battle Surprise!. He was sent out to battle against Sawyer's newly evolved Doublade. During the battle, Noivern used the dust on the battlefield to dodge Doublade's attacks and managed to defeat it with a combination of his newly learned move, Dragon Claw and a close-range Acrobatics. Noivern then battled against Sawyer's Clawitzer. However, because of Clawitzer's Mega Launcher ability, he was incredibly outmatched and was quickly defeated.
Noivern was released along with Hawlucha and Talonflame by Ash's Pikachu to train and later searching for Ash in a snowy forest before the blizzard had started. 
Noivern was sent out to meet Ash's Goodra with the others which he became good friends with already despite just meeting it for the first time then Noivern was seen with Greninja hanging with the Quagsires and a Lotad before another Lotad showed up to tell something to Goodra, who he and Greninja were the first to hear before everyone else. Later, Noivern teams up with Talonflame to find a wild Carbink who is missing until they found it being cornered by three Beedrill along with Florges and Flouette who causes mischief to them as theu return to inform Ash and the group. Noivern was seen in the pond hanging with the other Pokémon at the pond and it was seen with Greninja, Hawlucha, Pikachu, Goodra and Talonflame are excited to battle at the Kalos League. 
Noivern was used in Ash's six-on-six battle against Sawyer in the semi-finals of the Lumiose Conference. This time he went up against Sawyer's newly evolved Salamence. During the battle, Noivern and Salamence clashed each other with their attacks. However, despite giving his best efforts like doing a great amount of damage to Salamence and using his speed to dodge the Incinerate attack, both Noivern and Salamence were knocked out and their battle resulted in a draw.
Noivern was used as Ash's second Pokémon during his six-on-six battle against Alain in the finals. This time, he went up against Alain's Weavile. But despite using his speed, power, and sonic waves, Noivern was overwhelmed by Weavile and was easily defeated with a single Night Slash in explosion due to being hit from its Ice Beam from his right wing. Before Ash recalled Noivern, Hawlucha popped out of his Poké Ball to comfort Noivern and promised to defeat Weavile in his place.
Shortly after Team Flare and Lysandre began their assault on the city, he was captured and hanged up in the air with restraints unconscious at the time with Ash and the rest of his Pokémon at the top of Prism Tower by Lysandre behalf as a hostage for Ash and Greninja. Looking at the horror and destruction, after regaining consciousness, of Lysandre's plans, he became shocked and worried when Lysandre used the mini version of the Mega Evolution Energy Wave machine on Greninja and Ash but was relieved when they used Bond Phenomenon to break free and thanks to Alain's Charizard, Noivern and the Pokémon were set free and ready to battle.
During the battle, despite Noivern's best efforts, he was defeated by Mega Gyarados's Dragon Tail while saving Pikachu in the process. Hawlucha went to check on Noivern to see if he was alright before Ash called Noivern back to his Poké Ball.
Noivern had to say goodbye to both Goodra and Greninja before saying goodbye to all of Clemont and Serena Pokémon which at the airport, he held his hands with Braixen before bidding her farewell.
Since Ash finally comes home through his hometown at Pallet Town after his travels in the Kalos region and before the pilot episode of Alola to New Adventure!, Noivern, along with Hawlucha and Talonflame, currently resides at Professor Oak's laboratory.
