There have been at least three Bakugan
Tropes specific to the first Video Game (Bakugan Battle Brawlers):
- Artificial Stupidity: Prevalent in the Wii version (and possibly the other console versions), to the point where some people intentionally "skip" the AI throws so that they can land on a card for a change. The DS version has much better AI in this respect.
- Repeat after me: Dan is a handicap. It is likely you'll lose the first tag-team tournament solely because the idiot with Pyrus attribute (which has a disadvantage on the battlefield in question) doesn't make use of what he has. At least he always balances out the battles you're in by assisting you every time.
- Cap: You can only upgrade a bakugan 9 times. Additionally, each of the 5 stats caps at 5. The maximum base G-Power of a bakugan can only be obtained by ignoring all the other stats.
- Clear My Name: Leonidus (insert no 300 jokes) gets accused of a lot of things early on due to his late appearance (relative to every other bakugan) and coincidentally appearing just before Drago gets curbstomped by Vladitor. One of these includes an accusation of underhanded tactics against both Leonidus and his owner, you.
- Dark Is Not Evil: You have the option of starting with a set of Darkus bakugan at the start of the game, which sets Leonidus to be a Darkus bakugan. It doesn't affect the story one bit.
- Light Is Not Good: you also can have a Haos (light) Leonidus that initially wants the destruction of all bakugan. Incidentally, the ingame card artwork indicates Haos Leonidus is canon, since you cannot have more than one Leonidus. ever.
- Gang Up on the Human: In a 4-player free-for-all on the console version, The AI always helps whoever has the lowest G-Power level. even if that means helping someone who has 2 gate cards. On the DS version, the AI behaves more sensibly, always aiding the person with the least amount of gate cards.
- Hello, Insert Name Here: You're just referred to as "Kid" or "That Guy" or other vague nouns.
- Interface Screw: The confusion and mirror Hyper Ability Cards on the console versions. Mirror reverses the controls for steering the bakugan. Confusion distorts the screen itself. Both also screw up the AI's steering.
- Luck-Based Mission: "Fickle Finger of Fate" randomly changes the rate that the bakugan generates G-Power in a battle.
- Our Dragons Are Different: Leonidas◊, need we say more?
- Sealed Evil in a Can: Vladitor, who is only able to escape his imprisonment when the events that caused the Bakugan to appear on Earth in the first place transpire. Leonidus eventually surfaces from the Doom Dimension, but only shortly before Vladitor and Marduk appear and start knocking out all of the bakugan players.
- Virtual Paper Doll: You can choose from 5-6 styles for any part of the body, and from 6 colors for each one. That is the extent of it in this game.
Tropes specific to the second video game (Battle Trainer):
- Cap: Bakugan can only be trained up to level 12.
- Elemental Rock-Paper-Scissors: There are six elements; Pyrus (Fire), Aquos (Water), Ventos (Air), Haos (Light), Darkus (Dark-obviously) and Subterra (Earth). Each one has a weakness and a strength.
- Evil Laugh: Viper and Aurock.
- Louis Cypher: Dr. Trecov is actually Vector in disguise.
- Space Base: The Dark Star.
Tropes specific to the third Video Game (Defenders Of The Core):
