Gosei Headder Series — Seaick Brothers Set (2010)

Personally, I feel this set has two absolute winners, and one middle-of-the-road Headder that's just sort of there. The mouths open on both Hammershark and Sawshark, but the former's gimmick is severely underwhelming; the sides of the hammer are spring-loaded and move out all of a few millimeters. Whoo~ Sawshark is staggeringly large and utilizes gears as its blades. It's one of the best Headders in the series, imo. Manta Headder's wings can fold up and be released via a button, which is admittedly bleh, but I can't be upset when it gives Seaick Gosei Great a pirate hat and eyepatch.

Best pirate robo in Sentai? Yes. Yes it is

This set includes the Seaick Brothers' Summon card.

As usual, the BoA versions are lacking paint, and some size, compared to the originals, as well as all of the gimmicks. Manta's wings aren't spring-loaded anymore and Sawshark doesn't have a crank. You have to spin its gears manually. Hammershark is a fixed piece and the sides are elongated and slimmer. He came out on top, strangely enough.
