Fool. The heritage that you received was supposed to be mine. While you and the rest of our foolish siblings were blessed, I was cursed, and forced to give up the light and embrace the shadows. But no matter, for when I'm done with you, I will destroy our siblings, and conquer all!

Dementia (Full name: Dementia Synchro, originally Synchronite Nomad Matrix) (Japanese version 認知症, Ninshishō) is a former member of the Brotherhood of Matrix who was cast out of it after betraying his siblings in order to seize the throne of Matrix for his own personal gain.


An insane and remorseless deity with god-like powers, Dementia is a forced to be reckoned with in battle. His powers can leave his opponents as ashes, and can raze down almost anything in his path. He is considered a demon and an immoral entity among Matrix Bakugan.


Dementia is extremely insane, believing that causing chaos and destruction is the way to go. He enjoys shedding blood on the field of battle, and also enjoys slaughtering innocents. Dementia is also secretive and impatient, and highly intelligent - even far above the intelligence levels of Octavius. He is very sincere about his so-called "duty" to kill, and is merciless toward every being or creature he meets.


Dementia was originally known as Synchronite, and he was the third-eldest Matrix Sibling, after Octavius and then Celestial, and was often known as the "Blessed One". However, when the Matrix Siblings received their true heritage, he did not receive his, and went mad as a result.

Synchro then went into hiding, and discovered that he had not only the powers of Matrix Haos, which was his original Attribute, but some other, astral force that was a combination of shadow and necromancy. He then renamed himself Dementia, and named his unidentified Attribute after himself. He was not seen until a century after the loss of his sanity, attacking and razing down everything in his path in the Matrix Dimension. However, he was defeated and locked away by Celestial and the rest of the Matrix Siblings.
