The G-Power may be affected by Ability Cards and Gate Cards. It is found on the inside of a Bakugan in white or black writing. G-Power is also affected by Bakugan Trap, Battle Gears, BakuNano, Bakugan Mobile Assault, Battle Suits, Mechtogan, and Mechtogan Titans. Sometimes it can increase/combine when an allied Bakugan comes to join in a battle through an Ability effect.
When purchasing a Bakugan, the G-Power for the open Bakugan is usually covered with a gray sticker to stop customers from only purchasing strong Bakugan although sometimes the sticker is removed, fell off or is missing completely.
- The highest G-Powered Bakugan is a 2007 G Neo Dragonoid made of pure steel. It was won by Christopher Ruff during the Baku-Con Championship as one of the prizes. The second (non-evolution) Bakugan is Aquos Infinity Helios with 1200 Gs.
- 1000 G Neo Dragonoids were given out to each of the Baku-Con semi-finalists, 36 in all. 100 of them were made in total. A version of this Bakugan with silver highlights was later given to the first BakuMasters invited to the Bakugan Sneak Peek before the launch of Bakugan Battle Planet.
- In the anime, the concept of G-Power is used in the first, second, and the first half of the third season. They are not seen in the second half of the third season and not used in Season 4, up until End of the Line.
- The name "G-Power" was only used in the first season. Starting with New Vestroia, Gs were referred to as "points" instead.
