Gigant Edge is a large knight with green and teal armor. He has a dark green helmet with a white spike on top, a white chest plate, a black base, and teal armor. He carries a large sword and a large black metal shield with a spike in its center. Gigant Edge has two yellow markings shaped like swirls on his teal armor and orange feet. He has a V-shaped opening in his helmet like Sword Knight, but no visible eyes can be seen in the pitch-black space inside. His armor and insignias are strongly based on those of Blade Knight.
In Extra Mode, Gigant Edge trades in his green-colored armor for bronze and gold-plating, but is otherwise unchanged appearance-wise. His feet are also gold-colored as well.
Gigant Edge makes his debut as a mid-boss in Stage 2 of Cookie Country. He makes use of around 4 different moves: A dash attack where he rushes Kirby, a simple sword slash, a charged attack which sends out a shock wave, and a guard that momentarily reflects all damage.
In Normal Mode, he generally follows a pattern of sword slash > dash > guard > shock wave > dash > guard, from where it repeats anew.
However, in Extra Mode, Gigant Edge mixes his strategy up a bit and modifies a few of his attacks to be more brutal. For example, he may try to change direction in the middle of a dash, he may swing his sword up to six times in a sword-slash-attack, and he may skip the charge altogether in his shock wave attack, choosing to jump instead. He can even strike the ground to send three green energy spikes in an arch.
In this game, Gigant Edge returns as a mid-boss and once again yields the Sword ability. He looks and functions like he did in his past games, except he has a new form in the Extra Mode called Gigant Edge DX. In this form, his armor is bright gold and he has a few new attacks.
Gigant Edge's name is a combination of the words, gigantic and edge, as in the edge of a large blade.
