Kata

Kata is an envoy of the Morphin Masters, and the main protagonist of Power Rangers Omni Cross All-Stars. He was originally the Platinum Omni Ranger, but after the creation of the new timeline, he becomes the Red Omni Ranger. He uses a Master Morpher and can morph into any Legendary Ranger form as well as his own Omni Ranger form.

Power Rangers Omni Cross All-Stars
In Power Rangers Omni Cross All-Stars, Brady Seitz has caused an infinite time loop by sending Takumi Takeda back in time to destroy Ultimus in the past to prevent his own death, but in doing so he ultimately fuses with Ultimus to become the villain himself. The Morphin Masters send Kata to investigate and undo the time loop.

Power Rangers Samurai Force
Kata, who is now the Red Omni Ranger, recruits red rangers from each series in order to go on a dangerous mission.

Abilities
As a Martian, he has the natural ability to shapeshift into other humanoids. He uses this ability to assume a human appearance and blend in with the people of Midgard. However, he assumes his true Martian form when around other aliens.

Master Morpher and Master Ranger Key
By using his Master Ranger Key with his Master Morpher, he has access to many, if not all, Legendary Ranger forms. Theoretically, the Master Ranger Key would be compatible with the Super Megaforce Ranger's morphers, allowing any of the Super Megaforce rangers access to any Legendary Ranger form.

Signature Weapon: Omni Saber
The signature weapon of the Omni Platinum Ranger. He rarely uses it since he already has the more powerful Raikiri.

Legendary Weapon: Raikiri
Like the Code-0 Rangers, he has his own legendary weapon: the lightning blade known as Raikiri. He can also use Raikiri while in certain Legendary Ranger modes such as SPD Shadow Ranger or Dino Charge Gold Ranger.

Morphing Call
"It's Morphin time! Omni star power! Platinum Omni Ranger!"

"It's Morphin time! Omni star power! Red Omni Ranger!"

Trivia

 * Kata's status as a Martian with the ability to shapeshift is a reference to Martian Manhunter.
 * Kata is the first alien ranger of the Power Rangers PTverse.
 * He is comparable to AkaRed from Super Sentai.
 * After the creation of the new timeline, he becomes the Red Omni Ranger, furthering the comparison.
 * Along with Brady, Kata is considered to be one of the most powerful rangers of the Power Rangers PTverse.
 * He is named after the karate term kata.
 * This was done because PT believed that Kiya was named after the karate term for spirit yell. Thus he decided to name an alien character after another karate term.


 * Is this a JoJo's reference?
 * His Zord (Star) and his ranger color (Platinum) are references to Star Platinum.
 * His arch nemesis is Brady Seitz, who is Code-0 The World. This is a reference to the final battle of Stardust Crusaders between Jotaro Kujo (Star Platinum) and Dio Brando (The World).
 * After the Code-0 The World crystal is destroyed, Kata stops being the Platinum Omni Ranger and instead becomes the Red Omni Ranger (because there won't be anymore Star Platinum vs The World?)
