So, what are Dark-types, really?
The Purpose of the Dark Type:
Dark-type's purpose was these few elements:
- Nerfing Psychic and Ghost types
- Providing a good coverage type
- Providing a black colored type
- Providing a nocturnal type
- Fulfilling the dark/evil element.
However, as time have passed, Dark-type became less of an Evil-type and more of a Feral-type. This was because most of the Dark-type's members were species of organic origin, even if they were partially inspired by demons and beasts, or predominantly non-animalistic. This was also partially because the bulk of Dark-type moves were physical contact moves, which turned into Physical moves in Gen IV. Because Dark-type lack the evil as element style moves it would have if it were specially oriented, Dark-type had to find a new orientation as a Feral-type. This was partially because Ghost-type became more associated with evil magic, leaving Dark-type without much options.
Another important thing about Dark-type was its association with other types. As the Evil-type, Dark-type was first associated with Psychic, which served initially as the Light-type for until Gen IV. After the introduction of Aura and Lucario, Dark-type became more of a Trickster-type, with Fighting-type becoming the Hero-type. However, after fairies were introduced, Dark-type gained a completely new counterpart, which retroactively removed its association with its previous counterparts. As such, Fighting and Psychic became their own counterparts as they were in Gen I, and Dark became the Feral-type to Fairies' Kind-type.
The Aesthetic Archetypes of Dark Types:
Dark-types are predominantly Black, but there are those who are Red, Purple and Gray. Aesthetically Dark-types fit into following categories:
This group contains organic or non-organic species of mythological origin. They might be species that are interpretations of mythical beasts, or organic species shaped into mythical beasts. They are generally in Field Egg Group, though some are in Grass and Water 1-2-3 Egg Groups. Non-organic ones can be in Amorphous Group.
This group contains species that are based on large mythological beasts or movie monsters. They are generally in Monster Egg Group, though some are in Dragon Egg Group.
Regular animals that happen to be carnivores or carrion eaters, they often appear in Dark-type as in fiction, Carnivore are Evil. They tend to be in animal Egg Group like Field, Bug, Water etc.
These are either species that are recolors and retextures of other archetypes from other types and RPGs, or they can be species that based on thugs, warlords, and generic villains. They can be in all Egg Groups, though Human-Like seems to be most common.
The In-game Archetypes of Dark Types:
Early Dark-types: The second most common archetype, this archetype started in Generation 3, with the introduction of Mightyena. They are species that have 410-450 BST. They tend to suck.
Early Type Archetype+Dark-type: This one is odder. This also started in Gen 3, but this archetype, unlike the previous one, is not exclusively a Dark-type archetype, but rather a common archetype from other species that happens to Dark-type as its primary or secondary type.
Mid-game Dark-types: The most common archetype, this archetype also starting Gen 3 with Absol. These archetype covers species in 460-510 range. They tend to have large movepools, but balanced stats.
Late-game Dark-types: The first archetype of Dark-types, starting with Sneasel, this is also the rarest. This archetype contains species who are encountered in the end-game. They tend to have low stats but are heavily min-maxed.
The Stat Archetypes for Dark Types:
Balanced: Species without much stat specification, they focus on stat boosts to differentiate them. Some have Moxie and Intimidate.
Annoyer: Fast species with low stats elsewhere, they use their Abilities and Moves to spam status moves.
Bulky Offensive: Conventional bulky offensive species, they are generally good in one offensive and defensive orientation.
Dual Defensive: There are no conventional walls in Dark-type, so these species fill the role. They generally lack HP to balance out their other defense.
Dual Offensive: Conventional offensive species are rare, so what we have are slow, frail dual offensive species.
Sweeper: Conventional sweeper. They hit hard and die fast.
Wall Breaker: Conventional wall breaker. They have mediocre stats all around, with neat defenses. They use high powered moves to punch holes.
