Gigant

Gigant (ギガント) is the first boss from The Ninja Warriors Again, appearing as a regular enemy in later levels.

Details
Gigant appears as a large android soldier. It mainly attacks with a forward punch and a uppercut, being also able to block the player's attacks.

In The Ninja Saviors: Return of the Warriors this boss has almost twice of its original size, meaning it cannot be thrown anymore, with only a few grappling techs from the Raiden working on him. In addition to his original moves it also gained a new stomp kick attack.
