How in the world do LC Pokemon learn powerful moves at level 5?

Question

If you make an LC team in your DS game.How in the world do they learn those moves at level 5?(To harsh?)Like Turtwig learning Leaf Storm.How do you do it?
(P.S. If the title is too harsh,just tell me.)

Answer 1

There are a couple of ways:

Breeding.

• If both parents know a Level Up move of the baby Pokemon, it will know it as well. If 2 Torterras both have Leaf Storm and breed, the baby Turtwig will know Leaf Storm.

Egg Moves.

• If the male breeding has an Egg move that the baby can learn, then the baby will know it. If a male Hitmonchan with Ice Punch breeds with a female Lopunny, Buneary will know Ice Punch.

TMs&HMs.

• If you have TM26 Earthquake, and you have a Level 5 Geodude, it can learn Earthquake. Simple stuff.

Move Tutors.

• If a Pokemon is eligible to learn an tutor move, it will learn it, regardless of level, when the move tutor is paid. Buneary can learn ThunderPunch at Level 1 from a Move Tutor.

Answer 2

OK, since you used Turtwig as an example, I will too :P
Turtwig learns Leaf Storm at level 45, so you are wondering how a level 5 one could know it too. Here's how:

1. Teach a Pokemon in Turtwig's Egg Group Leaf Storm (this Pokemon must be a male), at whatever method/level it must be. Turtwig and it's parents all are in the Grass Egg Group and all can learn Leaf Storm, so we will breed with them.
2. Have a female Turtwig, Torterra, or Grotle go in the daycare with the Male knowing the moves. The feamle must know the moves identical to the male that you want passed to the Egg Turtwig, if they are learnt by level up.
3. Once they have bred, you will get an Egg. The Egg will know some of the moves the father knew if you have done it right (See here), in this case Leaf Storm.

The main purpose of breeding is usually to obtain a Pokemon that knows certain moves. If the male Pokemon knows moves that the baby Pokemon is capable of learning, it will know them when it hatches from the egg. This is a good way to ‘reuse’ TMs that you taught a Pokemon and cannot re-obtain in another way like buying.

The baby will know any move that it learns at level 1. If both parents know a move that the child would learn by level up, the child will also know it upon hatching.

> Furthermore, there are some moves Pokemon can only learn by breeding - these are called egg moves, and are listed in our pokedex alongside the other moves. In most cases, a Pokemon in the same egg group learns the move by level up and can pass it on by breeding, but sometimes you need to ‘chain breed’ from one Pokemon to another to another.

If there are too many candidate moves that the baby can learn, they follow this precedent, with each new move overwriting previous ones:
1. Level 1 moves.
2. Moves that the child learns by level up, if both parents have them.
3. Any compatible TMs, HMs and move tutor moves known by the father.
4. Any egg moves known by the father.
