Dark Bladers

The Dark Bladers are a beyblade team appearing only in the first season. The team is composed by four monsters: Sanguinex, Lupinex, Cenotaph and Zomb. They are a vampire, a werewolf, a mummy and a Frankenstein creation respectively. They were turned into monsters by their hatred of the Majestics. Their agenda was to capture more bit-beasts to earn their goal to become better bladers. The Bladebreakers first encounter them in England, then on their way to France, then finally defeated them in Paris. They then kidnapped Kenny (Kyouju) during the Bladebreakers match against the Majestics, and said they were their (the Bladebreaker's) "personal monster cheering squad".

The Dark Bladers, or rather, just Sanguinex and Lupinex, reappear in the third season's epilogue (original version only). Lupinex is only seen from the face down but can be told that it is him from his telltale grin, hairy wrists and the fact that he is with his brother.

Sanguinex (voiced by Hiroshi Kamiya in the Japanese version and Chris Marron in the American version)

Sanguinex is the unofficial leader of the team and Lupinex's older brother. He was turned into a vampire by Robert. His bit-beast is called Drac-Attack and it is also a vampire.

He has endless patience when handling his little brother and is usually the one to calm Lupinex's nerves. He is actually polite and mannered but sinister and creepy. He only loses his temper when he either loses a match, when he thinks about Robert and when people wouldn't let him finish his sentences.

Lupinex (voiced by Tsutomu Takayama)

Lupinex is the hot-headed werewolf-looking guy of the team and also Sanguinex's little brother. He was turned into a werewolf after being defeated by Johnny. He, ironically, is short-tempered and sharp-tongued like Johnny. His bit-beast is Wolf Storm.

Cenotaph (voiced by Kenichi Sakaguchi in the Japanese version and Robert Tinkler in the American version)

He is the mummy-looking guy in the team. He was defeated by Enrique, and as imagined, turned into a mummy. He was the first one to appear in the anime. He is supposed to be the brain of the team since he does all the dirty work. He has a creepy voice and likes scaring people (especially Kenny). His bit-beast is called sarcophagon/sarcophalon and it is also a mummy.

Zomb (voiced by Yuka Imai)

He is the Frankenstein's Monster-looking guy of the team. Despite his size, he is not very strong. He is actually very quiet and gentle (considering the fact that he is "human-ly challenged"). His bit-beast is a Frankenstein and its name is named Shamblor, which is also a Zombie/Frankenstein's Monster. He became one because of his defeat by Oliver.
