==Blurb==
Ash excitedly arrives in the Unova region along with Pikachu, his mom, and Professor Oak. Meanwhile, Team Rocket's boss, Giovanni, has given them an important assignment in the Unova region. As Jessie, James, and Meowth prepare for their new assignment, Professor Oak introduces Ash to Professor Juniper, one of the top researchers in Unova.
Suddenly, a dark storm cloud appears, and Pikachu is hit with a massive amount of electricity! Professor Juniper does a quick examination of Pikachu, but she doesn't seem to find anything wrong. Later on, however, when Ash battles a budding new Trainer named Trip and his first Pokémon Snivy, Pikachu can't use any Electric-type moves!
Back at Professor Juniper's lab, we learn that Pikachu is still suffering the effects of the lightning strike during the thunderstorm. Just as Professor Juniper reaches her conclusion, the same dark cloud appears as suddenly as before! The professor then recounts the story of the Legendary Pokémon Zekrom, and everyone wonders if it could be responsible for the mysterious disappearance of Pikachu's Electric-type powers. Will Pikachu ever be able to use those powers again?
==Plot==
 runs into his bedroom, grabs his backpack, and hurriedly runs out. As he returns to retrieve his , he expresses his excitement to Pikachu about their upcoming vacation. walks into the room, informing him that has arrived to pick them up, whilst proceeding to adjust his hat with a smile. Seeing the Professor's Pinap Berry shirt, Ash questions Professor Oak on his style of clothing, but he explains that he is headed on vacation after all. Delia inquires about Professor Oak having to work in Unova, but he tells her that he has quite a bit of free time when he is not attending seminars. Ash and his mom join him in the car.
Meanwhile, within the , questions Jessie, James, and about Team Rocket's goals: to obtain strong and rare Pokémon, and to form a formidable army of Pokémon to take over the . He tells the trio that the Unova region will be a strong foothold for their world domination plans and has given them the important mission of infiltrating the region alone, for now. The trio accepts the mission. After the reception is cut, Giovanni leans back in his chair and tends to his . His secretary appears by his side and informs him about the operations of a mysterious organization in Unova, but Giovanni does not flinch. He is, after all, confident that Jessie, James, and Meowth will force this organization in question to reveal their identities and operations, allowing them to strike at the opportune moment. He just leans back and takes a drink, smiling.
Ash, together with his mother and Professor Oak are now on board a plane heading to Unova. Unbeknownst to them, Jessie, James, and Meowth are on board the same plane. Dressed in dark coats and speaking in hushed voices, Team Rocket spots Ash and his Pikachu and decides, on the spot, to capture Pikachu as their first objective once they land as they get distracted. Meanwhile, Ash is reading a brochure on the Unova region. Professor Oak tells him that the Pokémon native to Unova cannot be found in any of the other regions, namely Kanto, Johto, Hoenn, and Sinnoh, and Ash becomes extremely excited.
Emerging from the clouds, the plane finally arrives at the Unova region. It makes a gradual turn and slowly descends into the sea and docks near a pier. Ash expresses relief after landing and together with his mother and Professor Oak, they make their way out of the pier. Pikachu suddenly detects something, stops, and turns to face the sea. He runs forward with his attention now focused on the dark spiraling cloud looming overhead. Ash, witnessing Pikachu's odd behavior, turns back, but becomes distracted by an leaping out of the water. Ash reaches the end of the pier and searches for the Alomomola, but it seems to have disappeared. He notices the same ominous black cloud that Pikachu had spotted, surging with erratic bolts of electricity and moving even closer.
Suddenly, out of nowhere, a metallic frame traps Pikachu. Ash instantly grabs the cage and tries to pry it open and catches sight of Pikachu's captors: three figures dressed in black coats topped with dark hats and sunglasses. Upon asking who the three of them were because of their disguises, they replied with two lines that would signal the start of their motto, and reveal themselves as Team Rocket.
Ash tells Pikachu to use , but it fails to shock the trio as they open a shield to deflect the attack. At the same time, the swirling black cloud draws ever closer, threatening to engulf the sky in darkness. Suddenly, a large bolt of blue lightning descends, sending Team Rocket flying and freeing Pikachu from the cage. Ash and Pikachu are also sent spiraling towards the ground. Amidst the shining flecks of blue and white light surrounding him, Ash gets up and spots Pikachu being zapped by a bolt of blue lightning. Curious, he looks up at the blue core and notices it shining even brighter than before, radiating both light and electricity. While Team Rocket backs off slowly, Pikachu aims some electricity at the central blue core. However, the electricity dissipates entirely. With glowing red eyes, a descends, summoning forth more lightning, causing the core to glow an exceedingly intense blue.
Amidst the broad daylight, a and her pop out from a tree and notice the dark swirling clouds at a distance. Curious, she leaps from the tree and grabs a vine, swinging her way towards the disturbance. At the same time, Delia becomes concerned about her son and heads off with Professor Oak to see if he is all right. Zekrom musters its strength and summons a gigantic bolt of blue lightning with its tail, shocking Ash and Pikachu before disappearing. Immediately, the dark clouds clear to make way for the bright blue sky above, and electronic equipment in the area mysteriously regains power. Ash wakes up to find Pikachu exhausted from the ordeal. Joined by his mother and Professor Oak, he assures them that he is all right, but suddenly notices Pikachu's cheeks spontaneously emitting sparks. Pikachu, however, assures Ash that he's fine and climbs onto his shoulder. Delia starts talking about the thunderstorm. Even though Ash tells them that he saw a Pokémon's shadow from within the clouds, they cannot confirm nor argue otherwise; from their point of view, they only saw a large black thundercloud.
Professor Juniper soon arrives, apologizing for being late. Professor Oak introduces her as a young, but very important Pokémon Professor in Unova. Professor Juniper drives the group back to her laboratory in a red SUV. On the way, Ash expresses his sheer excitement as he spots a herd of , a flock of and a scurry of . All of a sudden, Pikachu's cheeks start emitting sparks, and Professor Juniper suggests giving Pikachu a check-up at her lab. Ash agrees. At that moment, Professor Juniper becomes curious about Pokémon in the Kanto region and requests Professor Oak to tell her more later. Ash interrupts her conversation and asks if are rare in Unova, and she replies that they have never been encountered in the wild. The SUV makes a gradual turn to the right near a lake, and Ash watches a flock of fly across the water.
Eventually, the group arrives in Nuvema Town, and soon Professor Juniper's lab. Over there, Pikachu's condition is being monitored, and Juniper admits the numerical data doesn't show any discrepancies, but further tests will be required. A lab assistant enters the room, announcing the arrival of a new who is due to receive their first partner Pokémon. Professor Juniper greets the new Trainer, Trip. Ash interrupts the conversation, talking about how excited he was the night before he became a Pokémon Trainer. Professor Juniper introduces him to Trip. Upon learning that Ash comes from Pallet Town, he smirks and passes it off as some mediocre country town, to which Ash takes offense. As Professor Juniper tries to calm the two Trainers and prevent them from fighting, she sends out the three first partner Pokémon, first starting with the , followed by the , and the . After a moment of deliberation, Trip takes out his camera, snaps a quick picture of the three, and announces that he will choose Snivy. The smirks, leaving Tepig slightly annoyed and Oshawott extremely shocked. As is standard for beginning Trainers, Trip is also given a Pokédex which he uses to check the data of his new partner. He is also given five s, along with Snivy's Poké Ball. After recalling Snivy into his Poké Ball, he thanks Professor Juniper and takes his leave.
While Trip walks away from the lab, Ash catches up to him and questions him about Gym matches in Unova. Similar to Kanto, a Pokémon Trainer in Unova has to collect eight Gym Badges before they can compete in the Unova League. At that moment, the now-recovered Pikachu runs out of the lab and rejoins Ash. Completely shocked by Pikachu's appearance, Trip checks his Pokédex and starts snapping pictures. Trip realizes that Pikachu is Ash's partner and decides to test the Mouse Pokémon's strength by challenging Ash to a Pokémon battle.
Making their way to the clearing near the lab, Trip sends out Snivy and starts taking pictures to document his journey and his first-ever Pokémon battle. Meanwhile, Oshawott curiously peeks at the two Trainers from behind a nearby tree. Pikachu begins the match with a , which makes a direct hit on Snivy. The Grass Snake Pokémon quickly gets back on his feet, brimming with determination. Trip calls for a , but Pikachu dodges it skillfully. With another leap, he dodges another Tackle from the opposite direction. Ash tells Pikachu to use , but he is unable to do so, allowing Snivy to Tackle him to the ground. For a second time, Pikachu charges up a Thunderbolt, but the move fails once again. Trip taunts Ash, who takes the bait and tells Pikachu to use . Pikachu runs towards Snivy attempting to charge himself up, but once again, nothing happens; he loses momentum and stops in the middle of the field, panting. Ash panics for a moment, something for which Trip taunts him even further. He realizes that Pikachu is unable to use his attacks, so Ash calls for an attack instead. Pikachu's tail hardens into a gleaming slate of metal and slams earthward, but Snivy nevertheless dodges once again. With a bout of confidence, Trip tells Snivy to use , which traps Pikachu in a cyclone of grass and leaves. Pivoting his body, Snivy slams his tail to the ground, whipping up a large cloud of dust. As the dust settles, Pikachu lies sprawled in a hole, completely unconscious. Ash quickly runs to Pikachu's side and picks him up, while Trip compliments his Snivy and recalls him into his Poké Ball. Trip suggests Ash go over the Trainer basics again, but Ash ignores the comment and rushes back to Professor Juniper's lab to have Pikachu treated.
Professor Juniper, after another analysis, tells Ash that Pikachu became 'overloaded' and unable to perform Electric attacks after receiving a massive amount of electrical energy during their ordeal under the mysterious black cloud. Ash worries that Pikachu might never use Electric attacks ever again. At that moment, the lab's electronics start receiving a lot of interference, and the black cloud that was spotted previously at the pier is now moving over to Professor Juniper's lab. The equipment Pikachu is hooked up to begins discharging, shocking the Mouse Pokémon. Meanwhile, the girl and her Axew from earlier, stand quietly within the leafy branches of a tree, observing the black cloud forming above Nuvema Town.
A bolt of lightning suddenly strikes the lightning rod at the top of the lab, and the facility blacks out. Excessive current from the lightning bolt channels to Pikachu through the electronic device, causing the streaks of electricity to discharge from his body. Professor Juniper asks an assistant to restore the power, and he runs out of the room, forcing the automatic door open in his wake. Meanwhile, gazing at the black cloud through the window, Professor Juniper realizes the Legendary Pokémon Zekrom is behind the lightning show. She explains that Zekrom is a guardian that is said to protect both people and Pokémon in the area. Within the dark clouds, Zekrom's eyes gleam through the surrounding darkness in bright red, as lightning strikes all around Nuvema Town.

* This and the following episode are the first episodes to air in Japan after the earliest releases of in Japan, .
* This episode marks the first time that the first episode of a series has focused solely on since Pokémon - I Choose You!.
* According to the narration at the beginning of the episode, Ash is still 10 years old, despite the fact that has been airing for over thirteen years at this point. However, statements from previous series that have alleged otherwise can be reasonably refuted based on context, including:
** In the episode The Battle of the Badge, the line about not being in Viridian City for one year was a dub added line. In the original, it was only stated that it had been a "long time" since the group had been in Viridian.
** In Pikachu and Pichu, Ash didn't say a year has passed when he said, "This is the day we first met. The day we first became friends." However, it implies it has been a year, and the Pikachu short's place in the Pokémon the Series canon, as well as all of the other Pikachu shorts, can be brought into question.
** In the episode When Pokémon Worlds Collide!, the moment where said they had been chasing for as long as had been alive (ten years) was probably an exaggeration, or maybe due to breaking the fourth wall (since the episode in question aired during the tenth season of Pokémon the Series).
* For the first time since the start of Pokémon the Series, Ash receives a physical redesign, with the most significant change being his irises being enlarged in order to match Ken Sugimori's recent character art. Jessie, James, and 's eyes are also similarly modified, while 's eyebrows were made larger and his hairstyle became more boxy.
* Also, for the first time since the series began, Jessie, James, and are given costume changes, and the Team Rocket logo is also modified, now showing as a stylized "R". However, the logo on the uniforms of Jessie and James remain the same.
* The first scene of this episode of Ash getting ready in his bedroom is a callback to the first scene of Pokémon - I Choose You!, in which he was seen doing the same thing.
* Several of the items in Ash's bedroom at the beginning of the episode are those he received during his travels through Sinnoh. These are:
** The Soothe Bells he received after winning the Hearthome City Tag Battle Competition in Smells Like Team Spirit!.
** The Focus Band he was given at the end of Bibarel Gnaws Best!.
** The wooden model of a he was given as a gift from in A Full Course Tag Battle!.
** The diploma he received for attending the Pokémon Summer Academy in One Team, Two Team, Red Team, Blue Team!.
** The certificate he received for winning the Squallville PokéRinger competition in Pursuing a Lofty Goal!.
** The trophy he was awarded by Palmer for winning the in Challenging a Towering Figure!.
* This is the second time Ash has arrived in a new region and Pikachu has had problems with its electricity, the first time being in Hoenn during Get the Show on the Road!.
* Two new eyecatches were shown:
** The first one featured Ash wearing his Best Wishes clothes with his Pikachu standing alongside him and 's head in the background.
** The other one was also similar to the first one, but featuring Ash with his Pikachu on his shoulder instead and 's head in the background.
* The flight number of the plane Ash took from Kanto to Unova was "Flight 151", most likely to reflect the original 151 Pokémon.
* The English dub of this episode aired as a one-hour special along with Enter Iris and Axew!. This makes it the first time more than one new episode premiered during the same day since Tag! We're It...!, Glory Blaze!, and Smells Like Team Spirit! aired together back on February 1, 2008.
* This is the first episode to feature Who's That Pokémon? since 4Kids removed it almost seven years before.
** This is also the first episode dubbed by The Pokémon Company International to use an eyecatch.
* This is the first episode to use music from Arceus and the Jewel of Life, after Trip defeats Ash.
* The dub of this episode confirmed the localized name of Nuvema Town, much like Sandgem Town's English name was confirmed with the airing of Home is Where the Start Is!.
* This and the next episode was aired in Italy on DisneyXD one day after the American airing.
** This marks the first time an episode is aired in Italy one day after the American airing.
* In early previews of this episode shown at the end of Memories are Made of Bliss!, some changes were seen in relation to the episode aired. The scene from first between Ash and Trip initially went to a location within the city and not in a forest around the lab. However, the result of the battle is still the same.
* Team Rocket doesn't recite the making it the first time not to do so in the Unova region.
* This is the only episode after A Farfetch'd Tale where Jessie does not have a on hand.
* In the title opening introduced in this episode, there are six Poké Balls that are in the same order as they would be when healing in a Pokémon Center in .
* The shirt that Professor Oak is seen wearing at the beginning of the episode (with the pineapple pattern) is extremely similar to the one he wore in Beauty and the Beach, the only difference being that the shirt was yellow in that episode while it is green in this one.
===Errors===
* In one scene, Pikachu's left ear is missing the black stripe on the tip.
* In the Cartoon Network dub, describes Team Rocket's ambition as "green rule" over the world instead of "our rule".
* In the Hindi dub, when Professor Oak says "Sinnoh", he pronounces it wrong by saying soineh. In the same conversation, Ash mispronounces "Unova" as yuneva.
* In the Hindi Hungama TV dub, the narrator says the Pokémon world is inhabited by "", which means imaginary creatures. This could be a translation error of the word "imaginable" from the English dub.
** The Hindi Cartoon Network dub leaves this word untranslated.
* The dub's episode title, "Ve stínu Zekromu!", incorrectly handles 's name as if it was a non-living object. The grammatically correct title would be "Ve stínu Zekroma!".
===Dub edits===
* In the control tower scene, the controller clears the plane to land in the dub, while in the original version, he merely announces that the flight will be arriving soon.
* In the English dub, Giovanni tells Team Rocket that they will be sent undercover to the Unova region and that they'll be by themselves at first. In the Japanese version, he adds that it's another step to conquering the world.
* In the Japanese version, Professor Juniper says that Zekrom's thunderclouds are known as the "eyes of God" and that its thunderbolts are "judgements from God". In the English dub, she says that Zekrom watches over people and Pokémon and that the thunderclouds are the pillars that hold up the skies. These pillars may have been based on a famous which is also found in the .
** Both the Hindi dubs follow the original Japanese version on Zekrom but drop all mentions of God.
