Users of Electro can channel electricity through parts of their bodies in order to shock anything they touch. This power can also be channeled through weapons. This technique grants extra damage to attacks, giving the opponents electric burns and paralysis.
All minks can use Electro' including infants and the elderly, and it seems to be common knowledge among them. The inability to produce Electro is a telltale sign of not being a Mink, as Carrot indicated by Randolph's lack of the ability to do so.
So far, Carrot is the only known Mink to have any named techniques derived from Electro:
Eleclaw (エレ爪 (クロ),Erekuro?): Carrot uses Electro to charge up her fist with electricity and attacks her opponent by leaping onto them. It was first used to attack Charlotte Brûlée. Eleclaw is a portmanteu of the "elec" root several electricity-related words originates from and "claw".
Electrical Luna (エレクトリカルルナ,Erekutorikaru Runa?, literally meaning "Electrical Moon"): Carrot charges up a ball of electricity with both hands and slams it into the ground, causing a wide-range blast capable of electrocuting several foes at once. It was first used to defeat Randolph and several of Brûlée's underlings, and at the time, the water spilled on the floor beneath them enhanced the power of the attack. "Luna" is Spanish, Italian, Czech and several other languages for "Moon".
