As the trainer were divided into different levels similarly Pokemon too have their own respective divisions and mostly is based on the level of their racial number. For the fully evolved Pokemon such as Charlizard had a racial value of 530 while that of Gengar is 500 and of bug such as Butterfree and Beedrill is 395. It can be said that Charlizard is much stronger than Butterfree, but this is based on skill and raising the Pokemon to it's potential or there would not be a bug type elite four in the future.
After all Butterfree is bug and psychic type and this will be used as the criteria to defeating it. Well every trainer has different way of training and raising their own Pokemon. This is also a differential point in the fact that different Pokemon of same species had different powers and strength. Also it is also based on fact on amount of resources used to raise one, but for the current Alex he is facing a grand dilemma. His starter will not take much resource from his hand but to raise Charmander he would have to cut a piece of flesh of his own.
For Charmander many unflammable objects were needed as they could catch fire and then special appetite for it's healthy growth was also needed. In the forest he most fed him Dead Rattata or Ekans as for also let it hunt it's own prey. After all it's fangs and claws were made for hunting. Raising Charmander is similar to raising a carnivore pet like dog you could feed it and raise it without meat but it would lose its wild nature.
Now the wild nature of the Pokemon is also a power too as at times it's innate instinct may help it in battle. Over the course of time, Alex has some great moves which it probably inherited from its parent. This also let him be wondering about the strongest as well as suspicious about his identity. Nowadays people are not so kind to help each other. Many Trainer out there can't reach even the league is also due to the fact that they die in the journey. In the journey they are either killed by wild pokemon, killed by their own Pokemon, by other trainers, thief, poachers as well as some big families who holds enough power in the region around and kill them when they are offended. As for the league it doesn't do anything as for it the value of the family is much greater the a new trainer or it's potential was not enough to tackle the other. Of course on the bright side no one dare to kill but who has seen the dark. So now in the world were anyone could kill the other anytime why would he do so. Well how could he know that the stranger saw in him a person who got the title of "the Destroyer" and this is enough for him to give him a helping hand.
Anyway for diet of Charmander it composed of meat of animals it killed ( in this Alex only guided it in the beginning later asked it to face them on it's own.) Now he also trained them to act autonomous in the battle and if he felt he needed to command them he would say. And during his time before his travelling he spent hours in the library or browsing through many books and he had enough knowledge to become a primary cultivator ( Pokemon breeders who help raise Pokemon and also breed them. They also are able to nurse their Pokemon to heal them) .
We can say that every nurse joy in a Pokemon center of the main gym ( gyms we know from Pokemon games) is a senior cultivator and in other lower towns or places are intermediate gyms. Heck some top cultivator have same status as that of Pokemon gym leaders too and can be considered an indispensable part of the league. Every top cultivator is provided with enough to live happily without any work for lifetime. As for why he doesn't do the exam for cultivator is because he is very weak now. If he by any chance passed although it will only direct some attention of league it will also let other organizations in the league as well as criminal organization to him and he is not strong enough to protect himself. By joining them it may help him grow quickly but he doesn't want to be bound to anyone. He wants to see how far he could reach on his own. His Charmander eats special pokecube he create for him made from the berries he found in the forest. As the pokecuber in the hoenn is not invented yet he used his own hand to make them. This help him also increase his intimacy for his Pokemons and also make them strong as it slowly strengthen their body and other attributes.
As the moves Charmander now knew were :
Growl
Scratch
Ember
But also ,,,
Flamethrower (Though weak. Can only considered as stronger than ember)
Dragon dance ( probably had a dragon type parent)
Dragon Rush ( but this is only a stronger tackle attack)
So I. other to train it better Alex thought of a regime for Charmander by physical exercise strength it's body, by clawing trees sharpen it's claw for later claw moves, Boiling water for fire and he let it use dragon dance to control the dragon power. As for dragon Rush he now put it on the back as Charmander body can't handle the stress of weaker rush let alone train it . So he decided to strengthen it physically and train dragon Rush either after it learned dragon pulse so it could manipulate dragon power better or after it evolved to Charmeleon so that it's body can handle the stress.
Now he for dragon dance it could update only twice after third it could only handle only one attack after which it faints or could hold it for 5 seconds. And this is only due to it's superior linage. Now he had two new Pokemons he caught. A Caterpie which dared to stare at Ghastly even if he knew it would lose. it's battle spirit impressed him enough to capture him. And a Pidgey who knew wing attack he catch it. Both the Pokemon has different regime.
Caterpie is mainly trained in it's usage of string shot and he would ask it to swing around using it's string like Tarzan swinging on vines. And using the energy generated to tackle down it's opponent. Over the course of Five days it was caught it had defeated two rookie Trainer and Rattata, Pidgey and even weaken a Ekans which was later defeated by Pidgey.
As for Pidgey he mostly concerned about he wing strength and mostly glided over the same place to strengthen the wing. He also had strengthen the beak and claw by attacking the tree and rocks . Well Caterpie was caught later than Pidgey on the same day he fought Max. So before Pidgey he fed on Caterpie, Weedle and even Rattata. As for when it fought Ekans it ate it with help of Caterpie who weaken it. But after capture of Caterpie Alex asked it not to feed on Caterpie at least in front of Caterpie. He also let it find it's prey on it's own so that it's predator instinct is not diluted over time.
He also fed them his special berries cube. Each of his Pokemon Gastly, Charmander, Pidgey and Caterpie. Each had their own diet and recipe according to taste. As for why he nurture them himself elite trainer is at least intermediate level cultivator. So he too trained in it as it helps both in bonding and also train them well and help cut off cost for Pokemon care. After staying in the forest for at least a month he finally reached the city named Rock Town due to abundance of Geodude found around. He thought he would also challenge the gym here.
Well here we now see our hero having his first official gym battle . So let's stay tuned for a much more exciting Battle.
