The Naga's Twin Sister

Guardian Bakugan refers to the favorite or top Bakugan of a certain Bakugan brawler.

Guardian Bakugan's Information: ("There is a common misconception that Guardian Bakugan refers to talking Bakugan, as in actuality all Bakugan are capable of speech in the anime, with the exception of Mechanical Bakugan, Synthetic Bakugan, Chaos Bakugan, and the six Bakugan used by Team Anubias and Team Sellon"+"The term "Guardian Bakugan" was in fact never used in the anime"+"They were known as Partner Bakugan or simply Partners")

The White Ones are Bakugan that do not belong to any Attribute due to problems with their evolution. The only known members of this race are Naga and Wavern.

The White Ones' Information: ("The White Ones are powerless, mutated Bakugan that are born in between dimensions during evolution"+"This began during the Great Revolution - the conflict caused by the Original Dragonoid and the Original Dharaknoid, which made their universe split into the planet Vestroia; itself split into six different fragmented places; and Neathia and Gundalia"+"The split of Vestroia forced the White Ones to stay in-between the six shards"+"Also, they have shorter life spans than other regular Bakugan")

A long time ago, a mysterious force known as Code Eve constructed the first two Bakugan; Dragonoid and Dharaknoid based off genes from an unknown ultimate warrior. The two of them ripped their home universe into two separate realities. One contained the six attribute worlds of Vestroia, and the other Neathia and Gundalia. Vestroia was seeded by the Dragonoid, while the Dharaknoid seeded Neathia and Gundalia. In time more Bakugan emerged, and their origin was lost to legend. At the start of the series, only two full descendants of the original two remained, though all Bakugan are descendants of them.

One day, strange cards with Bakugan inside of them, fell from the sky on Earth and Vestal, because the Silent Core was stolen and the Infinity Core fell to Earth, creating a rift between dimensions. Within were the Bakugan, in ball forms. Dan and the Brawlers worked together to make rules for a game that used the Bakugan on Earth. They cannot take on their true form (as they were in Vestroia) in the human dimension, and take on the form of a sphere that pops out (or stands) into a miniature form. However, they can assume their true form when a Bakugan game is played.

These games start when the players shout "Field, open!", at which time stops. The game ends when someone wins.

Bakugan take many sizes and shapes, and generally comes in six Attributes, Pyrus, Haos, Subterra, Darkus, Ventus, and Aquos. Additionally, Naga and Wavern in the anime are referred to as "The White Ones". See Attribute.

Gate Card's Description: ("Gate Cards are the playing surface used for the Bakugan game. The cards contain a magnetic plate in their middle which triggers the Bakugan rolled onto them to open ("Stand").")

Gate Cards (Series 2 rules) come in three colors:

("Gold: Provide additional bonuses based on type of Bakugan. They replaced the original Character cards"+"Silver: Basic Gate Cards. They replaced the original Normal cards"+"Bronze (sometimes called Copper): Gate Cards with unusual abilities. They replaced the original Command cards")

("Gate Cards give bonus G-Power to based on their Attribute (Pyrus, Aquos, Subterra, Haos, Darkus or Ventus), with one attribute getting a "highlight bonus".")

("Cards may be Common or Rare, and there are special cards only available in the Arena product")

("In Bakugan Dimensions, Gate Cards are special Moves that set special conditions over the field"+"They dispel any Gate Cards before it when played and usually last about as long as the typical defense"+"(Darkus Gates are an exception to this rule as they will only dispel non-Darkus Gate in play, rather than dispel all Gates period. This means you can have multiple Darkus Gates in play at once.)")

Gold Gate Card's Description: ("Gold Gate Cards are a type of Gate Card framed in Gold"+"Gold Gate Cards often give a Bakugan a G-Power bonus once a certain condition is filled. Many of these cards are Bakugan-specific, meaning that if you want them to work properly, you should at least stock one of the stated Bakugan on the Gate Card (the name of the Bakugan will usually be the name of the Gate Card)"+"These cards replace the Bakugan Character Cards from the original series")

Silver Gate Card's Description: ("Silver Gate Cards are a type of Gate Card framed in Silver. They are the most basic Gate Cards and only a few of them have text. When looking for these cards it is important not only to consider putting in a Gate Card that give you a high boost, but also not so great boosts for your opponent.")

Copper Gate Card's Description: ("Copper Gate Cards (sometimes called Bronze Gate Cards) are a type of Gate Card that you can only have one of in the game. These cards have a variety of different effects and they are very valuable in the game. Many of them are helpful to Bakugan with low G-Power but high G-Power Bakugan can make use of Copper cards as well. These cards can change the game for you and easily put you back in the game if your losing by maybe giving you an Ability Card or letting you win an easy round. Copper cards are very valuable in game so choose wisely. These cards replaced the Command Cards from the original series.")

Private Gate Card's Description: ("Private Gate Cards sare a type of Gate Card that you can only use in the free time. Private Gate Cards are gate cards that offer a private space with your Bakugan to increase affinity with them. The private space are a unlimited space")
