To be able to gain the best advantage, it is essential to research and choose Pokemon to join the battle. The selected Pokemon not only need to have the strongest fighting skills but also need to calculate the countermeasures of Pokemon types against each other.
You can look up the skills and similarities of each Pokemon, but to understand the similarities between the systems, Pokemon Rom World invites you to follow our article below.
What is Pokemon Type?
Types (Japanese: タイプ Type) are properties applied to Pokémon and their moves, which affect the power of moves in battles. As of Generation VI, there are 18 types, as listed to the right. Most of these were introduced during Generation I, but the Dark and Steel types were introduced in Generation II, and the Fairy type was introduced in Generation VI. A unique ??? type also existed from Generations II through IV. During Generation I, types were occasionally referred to as elements. The types are largely based on the concept of classical elements in popular culture.
A Pokémon may have either one or two types. For instance, Charmander is a Fire type, while Bulbasaur is both a Grass type and a Poison type. With this system and there currently being 18 types, there is a total of 324 possible ways to assign types to Pokémon, with 171 unique combinations, 162 of which have been used as of Generation IX. Similar to Pokémon, Pokéstar Studios opponents also have types.
All moves have exactly one type each. The type of a damaging move typically determines which types of Pokémon it is super effective against, which types of Pokémon it is not very effective against, and which types of Pokémon it is completely ineffective against (with very few exceptions). If the type of a move matches one of the types of the Pokémon using it, it gains a boost in power.
Most Gym Leaders and members of the Elite Four are designed to have a type-specific theme.
Type Effectiveness
Type effectiveness greatly influences how much damage moves deal:
- If the type of a move is Super effective (Japanese: 効果はバツグン) against a type of its target, the damage is doubled;
- If the type of a move is Not very effective (Japanese: 効果は今一つ) against a type of its target, the damage is halved;
- If the type of a move has No effect (Japanese: 効果がない) against a type of its target, the target is completely immune to it, and the move will deal no damage.
For targets that have multiple types, the type effectiveness of a move is the product of its effectiveness against each of the types:
- If the type of a move is super effective against both of the opponent’s types (such as a Ground-type move used against a Steel/Rock Pokémon), then the move does 4 times (250% in Legends: Arceus) the damage.
- If the type of a move is not very effective against both of the opponent’s types (such as a Fighting-type move used against a Psychic/Flying Pokémon), then the move only does ¼ (40% in Legends: Arceus) of the damage.
- If the type of a move is super effective against one of the opponent’s types but not very effective against the other (such as a Grass-type move used against a Water/Flying Pokémon), then the move deals regular damage.
- If the type of move is completely ineffective against one of the opponent’s types, then the move does no damage regardless of how the Pokémon’s other type would be affected (as in an Electric-type move used against a Water/Ground Pokémon).
Popular Types in Pokemon
In the game Pokemon World, Pokemon types are divided into 18 systems, according to which:
- Normal

- Rock
- Fire
- Water
- Steel
- Poison
- Ghost
- Ground
- Dragon
- Grass

- Flying
- Dark
- Electric

Compatibility of Pokemon types in battle
Pokemon’s attacks are divided into 2 types: Physical Attack and Special Attack. For each type, there will be different effects depending on the incompatibility of that type with the attack type. Please study carefully the incompatibility of each Pokemon type to have a reasonable strategy in the attack-defense of the Gym, thereby becoming a good Pokemon trainer.
Please follow the compatibility of each type below. Whereby:
- 2x: Attack power doubled
- 1/2: Attack power is halved
- 0: No effect
- Offensive: Attack
- Defensive: Defense
The Normal type
The Normal type is one of the eighteen types of Pokemon. This type appeared in the first generation, which created 24 normal Pokémon. This was, in fact, the generation that most introduced such creatures. Today, after the release of hundreds of new Pokémon, we can count 97 little normal monsters, which make up 14.95% of all creatures. This makes Normal the second most common type of all, second only to Water.
On the other hand, when considering the techniques, Normal is the most common of all, as 167 of them belong to the type. And all that existed until the third generation was considered Physical, which meant that the Pokemon when using them, needed to make physical contact with their opponent to cause damage.
Most Normal Pokémon are single type, but there is a large contingent having the second type of Flying. Pokémon X/Y add several Normal dual-type Pokémon. In Generations 1-3, all Normal-type moves were categorized as Physical.
