Hybrid

Hybrid (ハイブリッド体 Haiburiddo-tai) is an artificial Evolution Stage comprised of Digimon who have been created using the Legendary Spirits of the Warrior Ten.

=Overview= The term "Hybrid" (sometimes glossed in kanji as 超融合 Chōyūgō, lit. "super fusion") refers to how these Digimon are literal hybrids of humans and Digimon, who are created when a human fuses with a Spirit. However, becoming Hybrids is not exclusive to humans, as ordinary Digimon are also able to use Spirits.

Like the Warrior Ten and their Spirits, Hybrid Digimon each have power over one of ten specific elemental powers: Fire, Light, Darkness, Thunder, Wind, Ice, Earth, Wood, Water, and Steel.

The power level of Hybrid Digimon varies, depending on the type and quantity of spirits that are used to create them, and can fall anywhere between Child-class to Ultimate-class power. Hybrid Digimon are all of the Variable attribute, meaning that their attribute changes in accordance with their current circumstances.

Although it is also created using Spirits, Susanoomon has never been classified as a Hybrid, and is instead a conventional Ultimate Digimon.

Forms
Hybrids are divided into five categories, called Forms (形態 Keitai), based on the type and quantity of spirits that are used to create them.

Power Level
It is common to rate the power levels of the Hybrid Digimon Forms on the scale of conventional Evolution Stages. The mechanics of video and card games often require that all Digimon, including Hybrids, be treated in some way as either equivalent to a conventional Evolution Stage, or treated as an ordinary Digimon who outright belongs to one of these Stages. However, attempts to do so have varied over the years and often disagree with each other.


 * Digimon Frontier: The concept of Evolution Stages is not mentioned at all, but the show presents each Form as a linear progression in power. Human Form Hybrids are depicted defeating Digimon as high-leveled as Perfect. Beast Form Hybrids are so much more powerful than Human Form Hybrids (aside from Duskmon) that defeating them is impossible without another Beast Form Hybrid. Fusion Form Hybrids are likewise significantly more powerful than Beast Form Hybrids (aside from Velgrmon, who is a match for the Fusion Forms), and Transcendent Form Hybrids are significantly more powerful than Fusion Form Hybrids.
 * Digital Monster Card Game: Hybrid Digimon (excluding Flamon and Strabimon, who are just assigned Level III (Child)) are always marked as belonging to the Hybrid level in the conventional Evolution Stage field of the card, but some Hybrid Digimon cards also denote a class. Human Form Hybrid Digimon are rated as Level IV (Adult) Class; Beast Form Hybrid Digimon are rated as Perfect Class; and Fusion Form and Transcendent Form Hybrid Digimon are rated as Ultimate Class.
 * Digimon Racing: Agnimon's three playable forms are all assigned natural Evolution Stages. Flamon is a Baby II Digimon, Agnimon is a Child Digimon, and Vritramon is an Adult Digimon.
 * Digital Monster Card Game Alpha: Hybrid Digimon are always marked as belonging to the Hybrid level in the conventional Evolution Stage field of the card, but each include errata that instructs the player to treat the card as if it belongs to a specified natural Evolution Stage. Human Form Hybrid Digimon are treated as Level IV (Adult) Digimon; Beast Form Hybrid Digimon are treated as Perfect Digimon; and Fusion Form Hybrid Digimon are treated as Ultimate Digimon. Transcendent Form Hybrids are not present, and neither are Flamon or Strabimon.
 * Digimon Masters: Each Form has its own separate Evolution Stage, which are each classed as roughly equivalent in power to a natural Evolution Stage. The "H-Hybrid" (Human Form Hybrid) stage is Adult-class, but slightly stronger; the "B-Hybrid" (Beast Form Hybrid) stage is Perfect-class; and the "Z-Hybrid" (Transcendent Form Hybrid) stage is Ultimate-class. Fusion Form Hybrids are not present, and neither are Flamon or Strabimon.
 * Digimon World -next 0rder-: Agnimon (Human Form Hybrid) is assigned the Perfect level; and Kaiser Greymon (Transcendent Form Hybrid) is assigned the Ultimate level. No Beast Form or Fusion Form Hybrid Digimon are present, and neither are Flamon or Strabimon.
 * Digimon Story: Cyber Sleuth Hacker's Memory: Agnimon and Wolfmon (Human Form Hybrids) are assigned the Adult level; Vritramon and Garummon (Beast Form Hybrids) are assigned the Perfect level; and Transcendent Form Hybrid Digimon are assigned the Ultimate level. Fusion Form Hybris are not present, and neither are Flamon or Strabimon.
 * Digimon Card Game: Hybrid Digimon are labeled accordingly in the Evolution Stage field on card errata, but for gameplay purposes they are also folded into the numerical "Level" system of Evolution Stages. Flamon and Strabimon are Lv.3 (Child); Human Form and Beast Form Hybrid Digimon are Lv.4 (Adult); Fusion Form Hybrid Digimon are Lv.5 (Perfect); and Transcendent Form Hybrid Digimon are Lv.6 (Ultimate).
 * Vital Bracelet Digital Monster: Human Form Hybrid Digimon are assigned the Adult level; Beast Form and Fusion Form Hybrid Digimon are assigned the Perfect level; and Transcendent Form Hybrid Digimon are assigned the Ultimate level.

When Hybrid Digimon are incorporated into evolution lines in traditional Digimon virtual pets, there is little to no consistency of assignment to Evolution Stages. For example, looking at Beast Form Hybrid Digimon, the Digimon Pendulum Z depicts Vritramon as an Adult Digimon, but the Digimon Accel Ultimate Genome depicts Bolgmon as an Ultimate Digimon.

Origin
Hybrid Digimon are the successors to the Warrior Ten. The Legendary Spirits that the Warrior Ten left behind after saving the Digital World in ancient times contain their powers, and grant their powers to those who use them.
