The Samurai Power Rangers are the fictional protagonists featured in the 2011 Power Rangers television series Power Rangers Samurai. The Samurai Rangers have existed for many generations to protect the world from evil monsters from the Sanzu River known as The Nighloks, who are led by the evil Master Xandred.

The Rangers reside at the Shiba House, their base of operations and use the kanji-based power called Symbol Power, which is passed down from one generation to the next. Symbol Power allows them to turn thoughts into power.

Once becoming a Ranger, they must stay clear of their friends and family to keep them safe from becoming a target of the Nighloks. The Shiba House is protected by special Defensive Symbols to keep the Rangers safe. They use a Gap Sensor to detect the presence of a Nighlok and its whereabouts.

The Rangers all carry "Spin Swords" that can utilize Samurai Disks. When a disk is attached to it, the Spin Sword acts as a praxinoscope and it powers up depending on the disk itself. The Spins Swords can be transformed into each of the Rangers signature weapon. When the Rangers summon their Zords, each Spin Sword transforms into a "Mega Blade". In the Zords’ cockpit, the Mega Rangers fold their Mega Blade and insert it and attach the standard Samurai Disk to the piloting system.

Lauren Shiba has not been a contender in any CBUB matches.
