Xiao Xia shook her head, dismissing her own guess; such a thing was simply impossible.
It was more likely that Pikachu's Wave Bomb was learned from Ash, but she hadn't seen Pikachu learning any Wave Bomb from Ash during this time.
And even if Pikachu learned Wave Bomb, why would Ash make the same pose as Pikachu? For style?
That was, of course, impossible.
In reality, Xiao Xia's guess was indeed correct; the reason Pikachu could learn Wave Bomb was because Ash and Pikachu had entered a state of perfect synchronicity.
One of the applications of Aura Power, 'Aura in My Heart,' is to combine one's own Aura with a Pokémon's Aura.
This not only enhances the Pokémon's strength but also allows the Pokémon to possess some Aura-related powers, such as the power to Detect mist and sense Aura when dealing with Team Rockets previously, and now, the Wave Bomb used against Geodude!
However, Pikachu alone, of course, could not use Wave Bomb; this skill is a display of advanced Aura control. Pikachu couldn't even sense its own Aura, let alone control it.
But with Ash, that was a different story.
Ash inherited all the abilities of Bo Dao Xiao Zhi. Even if he couldn't fully integrate them yet, he could still be considered a master of Aura control. After achieving perfect synchronicity and shared consciousness with Pikachu, Ash could naturally guide Pikachu to unleash Wave Bomb.
However, this operation was quite difficult. Ash would enter a 'fusion' state with Pikachu whenever he had free time in Chang Pan Forest, practicing Calm Mind and Aura control.
So, what Xiao Xia saw as Ash and Pikachu seemingly resting with their eyes closed was actually their exclusive special training.
The reason for this special training was also suggested by Bo Dao Xiao Zhi in the group chat.
Ash told the big shots in the group about the Pokémon he had and the moves they knew.
Tactician Xiao Zhi judged that even with Butterfree's hypnosis tactics, Ash would struggle against Brock because Brock's Rock and Ground-type Pokémon inherently possess extremely high defense.
It was best to use special attacking moves or super-effective moves to deal enough damage to them.
However, the special attacking moves Ash had were either resisted by Normal-type, Bug-type, and Flying-type attacks, or were Electric-type attacks that couldn't damage Ground-type Pokémon at all.
It wasn't impossible to defeat Brock with the Pokémon he had, but the battle would be dragged out, requiring constant rotation to wear down and torment the opponent, slowly grinding them down.
Ash's Pokémon were all too low-leveled. If such a prolonged battle occurred, any small mistake or excessive stamina consumption would mean that Brock only needed to hit Ash's Pokémon once, and the battle would be over.
Reverse-type battles are like this: a combo might be fierce, but the opponent only gets a scratch; then the opponent retaliates, and the battle instantly reverses.
To play reverse-type, you must bear the risks of reverse-type. When the level cannot completely overwhelm the opponent, reverse-type is an overwhelming disadvantage, which cannot be changed.
So Bo Dao Xiao Zhi proposed an idea: let Pikachu learn a Fighting-type move, Wave Bomb!
Fighting-type is super effective against Rock-type. If Pikachu could use Wave Bomb, then it would have a move capable of dealing powerful damage to the opponent.
However, theoretically speaking, Pikachu simply couldn't learn a move like Wave Bomb. Even for Fighting-type Pokémon, Wave Bomb is an extremely difficult and powerful move to learn. Pikachu, whether in terms of learning aptitude or level, could not possibly learn that thing.
But, Aura heroes are beings who break theory!
As long as Ash and Pikachu's synchronization was sufficient and they could fuse their Aura even deeper, then Pikachu would have a chance to use Wave Bomb!
The final result was as presented to everyone now: Pikachu successfully used Wave Bomb and successfully dealt heavy damage to Geodude!
"What are you posing for? Hurry up and finish it off! Use Quick Attack!" Seeing Pikachu posing, Ash couldn't help but lose his composure. If you want to show off, do it after the battle, okay? If the opponent retaliates now, you'll really have nowhere to cry!
Pikachu heard this and quickly turned its body, charging into the rapidly dissipating smoke with a quick step. Immediately, a dull sound echoed from within the smoke, and Geodude was blasted out, rolling twice on the ground before falling weakly.
Seeing Geodude's Aura gradually weaken, Ash finally breathed a sigh of relief. To be honest, even he was careless at first, thinking that Wave Bomb could directly defeat Geodude.
But the knowledge he had crammed during this period and Geodude's unyielding Aura warned him.
Brock's Geodude's ability is Sturdy. Pokémon with the Sturdy ability, when at full health, will forcefully retain a sliver of health if they take a hit that exceeds their maximum endurance.
Under the enhancement of Ash's Aura fusion, Pikachu's Wave Bomb had the power to one-shot, but the opponent had the Sturdy ability, so it endured the attack.
Fortunately, the opponent didn't recover from the heavy blow of Wave Bomb and was finally finished off by Pikachu's Quick Attack.
Brock silently recalled Geodude. In this battle, he didn't even touch Ash once before Ash ended the fight.
Compared to the previous duel with the young man named Gary, this battle was even more frustrating. Geodude was either asleep or slowed down, and those status conditions made Geodude unable to retaliate at all; it was too disgusting.
"What was that move just now?" Brock didn't immediately send out his second Pokémon but instead asked about the move Pikachu had just used.
As a Gym Leader, although Brock was young and his knowledge relatively shallow, that was only in comparison to general Trainers. For a Rookie Trainer to use a move he had never seen before was simply an incredible thing.
Moreover, this move heavily damaged Geodude, which has excellent defense. Brock even felt that if it weren't for the Sturdy ability, Geodude would probably have been instantly knocked out by that move.
So, this move was also super effective against Geodude? Otherwise, it wouldn't have caused so much damage to Geodude.
"Wave Bomb, a Fighting-type move," Ash didn't hide it from Brock and directly told him the move Pikachu had just used.
But this only deepened Brock's confusion: "Wave Bomb... I haven't heard of that move, but if it's a Fighting-type move, Pikachu shouldn't be able to learn it, right? At least, a Pikachu of your level couldn't possibly learn it."
Although Brock didn't have Ash's Insight Eye, as a Gym Leader, he had extensive experience and could roughly determine the opponent's Pokémon's level during a battle.
Pikachu's level was intermediate, which was quite high for a rookie, but an intermediate-level Pikachu should be completely unable to learn Fighting-type energy moves.
Just where did this strange boy and this Pikachu come from?
