Biography

Four Cross, known as Four Kurosu in Japan, is Three Cross's twin sister among Zero Cross's nine children in Beyblade X, sharing the Beyblade Umbra Sol D 5-70TK with him in its Double Smash Mode. Arrogant and merciless like her brother, she mocks weaker siblings and rivals but shows genuine coordination with Three, going first in matches so he can scout the opponent. The pair wins against Ginro and Nine Cross but loses to Jaxon Cross, Sigrid Nana-iro, and eventually Six Cross, whom the twins once looked down on before his launch power improved.

Appearance and personality

What They Look Like, and How They Behave

Heterochromia sets Four apart — her left eye purple, her right orange — alongside wavy purple hair streaked with orange and two moles set above and below her right eye; she's tall and pale-skinned. Like her twin brother, she wears a blue jacket with a white collar over a black undershirt and white shorts, hers trimmed in purple, along with thigh-high stockings striped in light blue, a moon necklace and dark grey shoes laced in purple. She often carries a small pouch alongside Three to hold their shared Beyblade, Umbra Sol.

Talent in blading leaves Four just as arrogant as her twin brother, and she often mocks bladers she rates as weaker, siblings Nine and Six included. That same talent means she rarely varies her approach, a predictability Sigrid exploits during their rematch. She takes offense, much like Three, at any suggestion that her strength rides on her brother's reputation rather than her own. Beneath the arrogance sits the same pressure driving her siblings: a desperate hope to win her father's approval, and a fear of what happens if Zero decides she isn't good enough.
