"Edge Imp Tomahawk" and "Edge Imp Frightfuloid".
They visually appear to be strange creatures made up of objects used for cutting or breaking, like scissors and tomahawks, with two glowing pink eyes within a shadowed area. According to Sora's Summon chants, the "Edge Imps" are objects possessed by demons, which could explain the menacing appearance of the "Frightfur" monsters, and their conversion into DARK monsters. In the TCG and English ARC-V anime, their blades are given a glow to avoid references to real life bladed weapons.
"Edge Imp" monsters work in tandem with the "Fluffal" archetype, being part of the Fusion Materials for their "Frightfur" Fusion Monsters. As such, "Edge Imp" monsters focus on getting themselves into the hand or onto the field to be used for Fusion Summons, as well as gathering more materials through drawing cards.
