The Star Fragment was a meteorite that landed on Earth long ago. It was responsible for creating the Beys, Storm Pegasus and Lightning L-Drago. L-Drago was used for evil, winning many wars and for frightening many townspeople. From this experience, it formed the shape that it has today. Pegasus was created to defeat L-Drago and eradicate the evil. This was successful, sealing L-Drago in crystal for 1000 years, until Ryuga, along with Doji and The Dark Nebula retrieved it to use it for their own evil purposes.
It was revealed that not only were Storm Pegasus and Lightning L-Drago created, but also a bey that was given the name "The Legendary Bey" due to it's uncontrollable power, Galaxy Pegasus W105R2F, that was the basis for Storm Pegasus.
Another meteor has also fallen down on Earth. An astronomer, Yuki Mizusawa saw it as it set it's target for Earth. It exploded before impact, releasing ten beams of light acting as Fragments. These beams hit the following beys:
|Beginning Bey||Owner||Evolved?||Result Bey|
|Galaxy Pegasus W105R2F||Gingka Hagane||Yes||
Cosmic Pegasus F:D / Cosmic Pegasus W105R2F
|Rock Leone 145WB||Kyoya Tategami||Yes||Fang Leone 130W²D|
|Meteo L-Drago LW105LF||Ryuga||Yes||L-Drago Destroy|
|Mercury Anubius 85XF||Yuki Mizusawa||No||Mercury Anubius 85XF Legend Ver.|
|Unknown Bey from King Hades||Aguma||Yes||Scythe Kronos T125EDS|
|Variares D:D||King||No||Variares D:D|
|Jade Jupiter S130RB||Dynamis||No||Jade Jupiter S130RB|
|Phantom Orion B:D (Attack Mode)||Chris||Yes||Phantom Orion B:D (Stamina Mode)|
|Death Quetzalcoatl 125RDF||Tithi||No||Death Quetzalcoatl 125RDF|
|Proto Nemesis||Rago||Yes||Diablo Nemesis X:D|
|Flame Sagittario C145S||Kenta Yumiya||Yes||Flash Sagittario 230WD|
Each Bey, with the exception of Jade Jupiter S130RB, Variares D:D, Death Quetzalcoatl 125RDF, evolved when it was hit by a Star Fragment and still contain the Fragments. When all ten Fragments are brought together in the Temple of the Black Sun, Nemesis will awaken and use The Black Sun as a vessel to start it's reign of terror.
In The Legend of Nemesis' Revival, it was revealed that unlike Yuki's theory that the star shattered out of its on willpower, Dynamis was responsible for the shattering of the star fragment, to prevent it from falling into the hands of evil, but the direction the fragments go are indeed of their own will. It was also revealed that even before L-Drago's time, a star fragment had met with the Black Sun and landed on Earth, resulting in the creation of Nemesis.
In An Inherited Light, Ryuga passed his Star Fragment on to Kenta to make him a Legendary Blader and replacing him as a Blader of the Seasons in order to seal Nemesis. Flame Sagittario then evolves into Flash Sagittario. L-Drago Destructor disintegrates after the transfer was complete.
In Light of Hope, it was revealed that each and every Bey in existence contains a Fragment of the Original Star, no matter how small it is. Every Blader in the world then passed their Fragments on to Gingka to defeat Nemesis. Even if the Bey is weak, the star fragments power inside the Beyblade grows with the Bladers Spirit!
- Mercury Anubius 85XF is the only Star Fragment Beyblade that does not utilise a 4D Wheel.
- Kyoya and Kenta are the only members of the Bladers of the Four Seasons whose Beyblades do not utilise a 4D Track.
