Ika Sticker

Ika Sticker (イカステッカー Ikasutekkā) is a Henshin device used by Neo SquidMask. With it, it can allow Neo SquidMask to transform into his Supercharged form. By applying (essentially sticking it) on his forehead, it can stick on there and not fall off. Once activated, it can generate much electrical power, granting the user electrical power; in this Neo SquidMask (although Neo SquidMask already has electrical powers, this can make him stronger and double the power). Neo SquidMask has to charge up his electrical power immensely and announce "SUPER CHARGE!" in order to access his Supercharged form.

History
The Ika Sticker was created by Unit 4 Sagiri with the intent of creating a device that could grant the user electrical powers. Sagiri tried it on herself, before then leaving it be. Neo SquidMask then got a hold of it initially without permission, before then using it to save the day by entering his Supercharged form. After apologizing, Sagiri then gave Neo SquidMask the henshin device, allowing him to keep it.

Trivia

 * It's current name was coined by Neo SquidMask. It gets it's name due to "Ika" in Japanese meaning squid and "sticker" because it functions similar to a sticker.
 * Prior to being called it's current name, Sagiri called it the Synth Maximizer.
