Another Seaick Gosei Great
When using the Manta and Hammer Headders as hands and the Sawshark Headder as chest armor, Gosei Great becomes Another Seaick Gosei Great (アナザーシーイックゴセイグレート Anazā Shīikku Gosei Gurēto?). First debuts in Epic 18.
- The Seaick Brothers can unite with Landick Brothers, Skick Brothers, Gosei Great, and Datas Hyper to form Hyper Gosei Great, and further with Groundion and the Knight Brothers to become Ground Hyper Gosei Great.
- The Hammershark and Sawshark Headders can unite with the Taka Headder, Landick Brothers, and Gosei Great to form Sky-Land-Sea Gosei Great.
- The Manta Header helmet resembles the hat of a pirate captain, with an eyepatch that acts as a scope to lock on to targets. This would serve retrospectively as a foreshadowing of the next Sentai after Goseiger.
- This gets called out on during Gokaiger Goseiger Super Sentai 199 Hero Great Battle.
- Unlike the other tribe brothers,The Seaick Headders can only be used by the three other Goseigers during battle because there is only one Seaick Tribe member in the team.
