The pack of pokemons is not happy with their leader's action, it backed down after a single exchange showing signs of fear and they didn't like it.
They are the strongest pack of Pokemon in whole Unova, they have taken over several jungles for its resources to feed their growing appetite to seek strength but a single jungle is not enough for them all so they migrate through jungles for food.
They circle around the whole regions after eating up all the resources, once they are back to where they started from, the jungle would have already restored itself with new resources.
It's their leader's job to claim these lands for its pack and with that, it gets the benefit of getting everything first, it gets more food, more land, and more females to mate.
Showing signs of weakness is the biggest mistake a leader of a pack can do in front of the pack.
The pokemons in the pack looked at the Garchomp and felt everything was normal as Garchomp hasn't still revealed the terrifying aura that is hidden inside him, some of the pokemons at the back started to get a little rowdy as they asked their leader, Bisharp to attack but Bisharp was not a fool.
It knew that the Garchomp in front of it is a monster and it shouldn't even think of having an exchange of moves with it, after thinking for a few seconds, it decided to take the best course of action, escape.
With a flash, the Bisharp ran away from the place leaving its pack behind, the pokemons were surprised by Bisharp's action, they realized that it abandoned them and now it is up to them to do everything.
The pokemons looked at each other and then at Garchomp, they knew that this one is very strong and that is why the Bisharp ran away, the responsibility of the leader is to fight off the opponent head-on and now that it couldn't do it, it escaped.
But this also made it possible for these pokemons to fight back, now they don't have any pokemon as a leader, they can gang up on Garchomp and beat him down, then they can dispute among themselves on who will be the new leader of the pack.
They all showed hostility towards Garchomp and defeat him and chase away the human that controls the Garchomp, little Axew didn't know what to do, it was the weakest pokemon in the pack, it was a new member in the pack.
The Bisharp asked it to join the pack as it saw that Axew was strong, the whole pack was formed with very strong pokemon and an addition of a new member will only strengthen the pack's power and influence in the wild.
Since little Axew was new to the pack, it didn't have much loyalty to it, it didn't care about fending off the pack, and being a dragon it only looked up to the strong and in its view, the Black Dragon Garchomp is clearly the strongest pokemon it has ever come across.
When Garchomp sensed the hostility of all these pokemons towards him, he decided to not hold back and roared loudly, his roar was so loud that the whole forest trembled, even the people living in the Black city were able to hear it.
He released his overbearing aura and caused the whole pack to back down in fear, the pack of pokemon realized why Bisharp didn't even think for a second to face of against this pokemon, it was because it was a monster at another level, even their whole group combined can't do anything to Garchomp.
They all hesitated, they could feel the gaze of a predator scanning through them, no one wanted to make the first move, they were all very intimidated, their morale is now at an all-time low, seeing that the pack on pokemon has already given up, Garchomp was a little disappointed.
Not wanting to waste his time with the weaklings, he decided to scare them away with another loud roar, this roar was even louder and horrifying than the one before, even the bird pokemons who were trying to pass through the forest stopped and made a U-turn not wanting to do anything with the thing that is inside the White Forest.
The people living in White Forest were scared out of their mind as they heard the roar for the second time, this time it was even louder than before, the children in the village started to cry after hearing the second roar, the first one had already terrified them.
The pack of pokemons backed of scared, they didn't want to do anything.
Garchomp then growled at them and told them to get out of the forest, the pack of pokemons nodded and quickly disappeared into small groups and left the forest without even thinking for a second, the strong ones became the leader of their own small pack as weaker pokemons followed them out of the forest.
The once-massive pack was not completely destroyed turned into a small group of pokemons, the only pokemon that is remaining is the small Axew, it just looked at Garchomp with awe, it wanted to become just like Garchomp, a terrifying dragon that can scare its opponents away with just its roar.
Julian had been watching Axew for quite a while and knew Garchomp made an impression on it, the reason why he sent out Garchomp in the first place because he knew this would happen, he has been observing pokemons for quite a while and Dragon being his favorite typing, he studied their behavior.
He knew how the young dragons looked up at a stronger pokemons and if that pokemons was another Dragon they would be in awe, even his Garchomp was like that when he was just a Gible.
He remembered how the little Gible looked up to his father and the other Garchomp it was battling the day Julian caught him, he then admired Gengar after Gengar displayed powers beyond Gible's imagination, he then saw how powerful Infernape and Snorlax are and that left a deep impression of Garchomp.
It was not only his Garchomp, but even his Flygon was also the same, after he evolved into his final form and turned into a Dragon it admired, Infernape and Snorlax more than anyone.
To a dragon, power is the most important thing in the world and the one who has overwhelming power can control them all.
The little Axew was the same, Julian just had to show it what real power is like and it will take the bait.
