Info Image Gallery Trivia

Siege (Japanese version Knight (ナイト, Naito?)) is a knight-like Bakugan.



Siege is a knight in shining armor. His silk cape is used both for flying and protection. He is equipped with a lance with different blade tips depending on its attribute.

Bakugan Official Handbook

If you are ever in trouble during a brawl, Siege can be the Bakugan in shining armor that saves you! Siege is fully protected thanks to its suit of armor. It lashes at opponents with its long, sharp lance.

Bakugan Ultimate Handbook

Siege looks like a knight in shining armor. He can use his cape to fly across the field or protect himself from an assault. He has a different tip of his lance based on his attribute and has high agility.


Bakugan Battle Brawlers

In the anime, Dan, Klaus von Hertzon and Kenta had Pyrus Sieges, Runo and Joe had Haos Sieges, Masquerade had a Darkus Siege, Marucho and Jenny had Aquos Sieges (the latter of whom's is her Guardian Bakugan), and another Aquos one was used by an Illusionary Marucho in the real Marucho's test set by Frosch. An Aquos Siege was also used by Rikimaru, given to him by Masquerade to defeat Dan, but lost it.

Physical Game

Siege was released in all Attributes. The Darkus version has 390 Gs and 520 Gs. The Aquos version has 550 Gs.

In the PS2 videogame, Siege is available in all attributes. Dan, Chan Lee and Klaus have a Pyrus Siege, Runo and Julio have a Haos Siege, Shun, Komba and Shuji have a Ventus Siege, Marucho and Jenny have an Aquos Siege, Marduk has a Darkus Siege, Julie, Jewls and Akira have a Subterra Siege.


  • For each attribute, Siege carries a different form of weapon in Bakugan form.
  • Jenny's Siege has the lowest power level out of any Bakugan with a power level of 90 Gs. Though this is likely because the only time when its Power Level was seen was when it was called as an assist thanks to the effects of the Attractor Ability Card, which only adds the 10s of the Bakugan's Power Level, thus it is more likely at 290 or 390 G.
  • After season one Siege's ability Aquos Javelin would not work due to the fact that a battle from Seasons 2-4 would use one Gate Card at a time or none at all. Unless in team battles, brawlers battle one-on-one.
