Ventus was created later than other 5 attributes so Ventus was not included in earlier Japanese gate card.
The symbol of the Ventus attribute is derived from the Han character for wind, 風 (kaze). Ventus comes from the Latin ventus, which means 'a wind'. Zephyros comes from the Greek Ζέφυρος, 'the west wind'. Its color is Green.
For Pyrus, the main point of them is to simply overpower through sheer force and shutting down ways your opponent can fight back like gate card bonuses or Ability Cards. Due to this, nullifying cards like Rikimaru's Surprise or Stand Off are very useful to stop your opponent from fighting back with ability cards or Gate effects and Stand Off also gives a great Pyrus Bonus.
Subterra Bakugan tend to have very high G-Power and a straightforward approach of
overpowering their opponent. Very much like Pyrus, but there is also an emphasis on overpowering your opponent so you can use some of your most powerful ability cards like Subterra and Sub Terra 2.
In game, color of Subterra Bakugan is light brown with darker brown highlight but earlier Japanese Subterra Bakugan has dark brown body with orange highlight, in Bakugan: New Vestroia Subterra Bakugan are a light orange color. The Subterra soldier of Vestroia is Clayf.
The symbol of the Subterra attribute is derived from the Han character for earth, 土 (tsuchi).
Haos Bakugan have some of the lowest G-Powers in the game
They don't need it though since strategy is the main idea of Haos. Haos often win by using cards that either switch the G- Powers like G-Power Swap, cards that win with the lowest G-Power like Tricky Gate, or using your lower power Bakugan to use very powerful ability cards like Haos 2 or The Glow.
The symbol of the Haos attribute is derived from the Han character for light, 光 (Hikari). It could also be argued that Haos is Chaos without the C.
Darkus Cards have a large variety of G-Powers and ability cards so their are many ways to use them.
A main part of Darkus Bakugan are sending cards away such as the Doom Card or Masquerade's Throw or manipulating what they do with cards such as Darkus 2.
The symbol of the Darkus attribute is derived from the Han character for darkness, 闇 (yami).
Aquos Bakugan usually have average G-Power but use trickery to either boost them or dwindle their opponent.
Many cards make the opponent feel safe and secure but then cards with powerful effects come up and shock the opponent like Preyas Switch, Aquos 1 or 2, Summon Wave, or Murucho's Launcher. With Aquos strategy, you want to put in low power Bakugan on an opponents gate card or something to make the opponent think they have the upper hand before you bring down a big ability card to knock some sense into them.
The symbol of the Aquos attribute is derived from the Han character for water, 水 (mizu). Its color is Blue.
