DinoZord

The DinoZord is the Red Samurai Ranger's third Zord that resembles a Saurapoda. It can combine with the Samurai Megazord to form into the Samurai Dino Megazord. It forms when the Dino Attack Disc is installed in the Spin Sword, which turns the bearer into Dino Attack Mode & allows for him/her to summon the zord itself.

It is controlled by the Dino Sword.

It was unlocked by Antonio using the LightZord.

Samurai Dino Gigazord
The Samurai Shark Gigazord is the final combination of all twelve Zords and true form of Samurai Gigazord. This form the Samurai Gigazord wield the SharkZord. Its "finishing attack, however, is to summon the symbol power of all zords, energizing the SharkZord to deliver the "Ultimate Samurai Slash".

The formation is only used once in Stroke of Fate, in Serrator's final battle.
