Alex closed his door to his room and thought over how he should train Zubat.

The improvement of Pokémon's strength depends on two factors. The first one being the physical fitness of the Pokémon, and the second one being the Moves mastery. ​​

Pokémon's physical fitness can be divided into six factors: HP, Physical Attack, Physical Defense, Sp. Attack, Sp. Defense, and Speed.

Pokémon's Moves mastery can be divided into three levels: Beginner, Expert, and Master.

Both the physical fitness and moves mastery can be improved with special training.

Let's say, for physical fitness training, you can ask your Pokémon to run at full speed for an hour. If you do it often enough, then your Pokémon will be faster than Pokémon of the same race that did not do such training.

Moves mastery can be improved if you use a move often in training or in combat. For example, Zubat's Shadow Ball was so slow, small, and weak because his move mastery of Shadow Ball was only at the Beginner rank. But if Zubat does this move 50 or even 100 times every day, it won't take long until his Shadow Ball is normal in strength, speed, and size.

Of course, every Pokémon is different. For move mastery, it is important to have good potential.

The better the potential the Pokémon has, the faster the Pokémon masters the move.

How to improve Pokémon's combat strength? There are two ways. The first is to fight against other Pokémon, and the second is to train (Moves mastery & physical fitness).

If a Pokémon increases its combat strength, its level rises. If a Pokémon is over LV 40, the Pokémon is considered an Elite Pokémon, and the trainer who owns such a Pokémon is called an Elite trainer.

But not every Pokémon can become an Elite Pokémon. Pokémon with a potential of Normal can only reach LV 39 max. And don't forget, the lower the potential, the lower ones leveling up speed.

Bronze Pokémon max. LV is 49.

Silver Pokémon max LV is 60.

Gold Pokémon max LV is 75.

Potential: Normal, Bronze, Silver, Gold, ???

Alex thought, "Zubat and his evolved-form Crobat are assassin-type melee Pokémon, especially Crobat. It is logical to train Zubat this way early. Let Zubat master a few more long-range moves too. Getting into hand-to-hand combat isn't always the best option for Pokémon like Zubat.

"Ok, I will train Zubat special for speed tomorrow. Speed is one of the most important stats for Zubat now. If he is fast enough, he can execute a hit & run tactic. Of course, even if he is much faster than other Pokémon, some moves can hit Zubat."

While Alex was lost in thought, he heard a knock on the door.

When he opened the door, Alex saw the same Team Rocket Lackey again, with a package with him. Alex received the package and closed the door.

The package included 3 Ultra Ball, 3 Team Rocket member suits, TM (Protect), 10 Energy Powder, and 10 bottles of Tauros's blood.

Zubat, who was bored sitting on Alex's shoulder, saw the Tauros's blood and started flying around excitedly in the room. After a few seconds, he calmed down and landed in front of Alex with a begging expression ༼ つ ◕_◕ ༽つ.

"Pokémon are so cute," thought Alex in his heart.

Alex: "HAHA! Ok, Zubat. I'll give you one of Tauros's blood bottles. But before that, I want you to do Shadow Ball 50 times. Also, be careful that you don't hit anything with it. I also want you to try to make the Shadow Ball as fast as you can without losing strength or stability."

Zubat nodded and looked at Alex seriously, then he flew straight to a spot in the room with the most open space and started practicing Shadow Ball.

Alex watched as Zubat made a slightly faster Shadow Balls. His Shadow balls are getting a little faster every time Zubat uses them. Although the progress got slower after 50 shadow balls, his Shadow Balls were 1 second faster than before (3s total). Now Zubat can make a shadow ball in 2s.

Suddenly, a thick smell of blood pours through the room when Alex opened the Tauros Blood. He placed the bowl of Tauros's Blood in front of the exhausted Zubat, and he also praised Zubat for his hard work.

"What a crazy day," thought Alex.

He put his exhausted body on the bed and fell asleep immediately.
