|Debut||Ninja Gaiden II|
GigaDeath is a large silver fish like creature. It has two large horns coming off of his head. Several round poles stick off of his segmented tail. The tail ends in a fin. Many spikes line the top of him.
Ninja Gaiden Sigma 2Edit
Ryu encounters GigaDeath in the subways of New York City. In order to carry on, Ryu must defeat him.
- Gigadeath's concept art has a seemingly normal human character next to it. It is unknown who this character was meant to be as they do not appear in the final game.
