Monarus (Japanese version Fairy (フェアリー, Fearī?)) is a butterfly-like Bakugan.


Monarus is a Bakugan that resembles a butterfly. It is one of the fastest Bakugan thanks to its large wings and ultra-lightweight. It has the ability to fly beyond Gate Cards. Its enormous butterfly wings create a mighty hurricane wind to defeat opponents.

Bakugan Official Handbook

Don't let the pretty Monarus fool you. Just because this Bakugan resembles a butterfly with its beautiful wings doesn't mean it can't do real damage in a brawl.

Bakugan Ultimate Handbook

This Bakugan looks like a beautiful butterfly, but don't be fooled by its good looks. When it flaps its wings, it can create a mighty hurricane wind to blow its opponents away! Lightweight Monarus is a super-fast flyer, and it can soar right over a Gate card to escape its effects.


Bakugan Battle Brawlers

Shun uses a Ventus Monarus several times in the series; in its first appearance, Monarus fought and saved Drago from being sent to the Doom Dimension.[1] Later, it once again saves a Bakugan from being sent to the Doom Dimension, this time Gorem.[2] In Shun's battle against Komba, it defeats Harpus and El Condor with Blow Away.[3] Shun later uses it against Oberus' illusory young Shiori, but it was defeated by Bee Striker.[4]

When Runo decided to quit playing Bakugan, a Haos Monarus can be seen in her basket of Bakugan.[5]

A Ventus Monarus was seen with Harpus trying to fend off Tayghen.[6]

  • Its name and appearance are based on the Monarch Butterfly.
  • There are a variety of things about Monarus that change, such as, the ovals on the back of its wings sometimes vanish, they are also sometimes diamond-shaped, also the yellow is sometimes close together, or spread out, its head is sometimes smaller, sometimes one of its eyes is bigger than the other, and a few other things.
  • In the DS version of the Video Game, a Pyrus Monarus is orange with red on the top screen, but it is red with orange on the touch screen, a Haos Monarus has a bit of an inverted color scheme and a Ventus Monarus appears normal, probably because it is Ventus in the anime.
  • In the anime, Ventus Monarus has red eyes, but while in the game, it has yellow eyes.
  • Monarus and Ravenoid are the only two minor Bakugan from season 1 that have an game exclusive evolution in season 2.
  • Monarus' rising battle cry in the Wii video game sounds like something Sirenoid might make.
  • Monarus is the only Bakugan that Shun possessed along with Skyress to not lose a battle and be sent to the Doom Dimension.
