Scarred Dragon Archfiend (Level 8): A core remake card added in the 'Pulse of the King' Structure Deck. It is treated as the original 'Red Dragon Archfiend' while on the field or in the GY. When sent to the GY as Synchro Material, it has an effect that destroys all Attack Position monsters the opponent controls, assisting in both plays and breakthroughs. Personality: Timid.

The Crimson King (Level 8): The main title of the overseas Structure Deck and a Level 8 Synchro Monster. It is a vital axis that serves as the lubricant and engine for the deck's plays. Personality: Very angry.

Red Nova Dragon (Level 12): Jack Atlas's iconic Double Tuning monster. Its ATK increases by 500 for every Tuner in the GY, soaring far beyond its base 3500, and it has immunity to destruction by opponent's effects, providing great field presence. Personality: A total old-timer/stickler.

Red Dragon Archfiend (Level 8): The original and the symbol where everything began. These days, it is frequently used to pressure the opponent by being summoned directly from the Extra Deck via the effect of 'Scarred Dragon Archfiend'. Personality: Fiery.

Soul Resonator (Level 3 Tuner): The god and top-tier starter card of this deck. If Normal or Special Summoned, it adds a Level 4 or lower Fiend monster other than 'Soul Resonator' from the deck to the hand. Furthermore, it provides useful destruction protection by banishing itself from the GY when a card on the field is about to be destroyed. Personality: Has very little presence.

Vision Resonator (Level 2 Tuner): Can be Special Summoned from the hand if there is a Level 5 or higher DARK monster on the field. It is an essential utility member that searches for Spells/Traps like 'Scarred Crimson Rain' or 'Crimson Gaia' when sent to the GY. Personality: Popular, a social butterfly.

The original and ancestor-like symbolic monster of the 'Resonator' archetype, first used by Jack Atlas in the Yu-Gi-Oh! 5D's anime. Personality: Surprisingly kind.

Crimson Resonator (Level 2 / DARK): The most important card for bringing out high-level aces. If this is the only card on your field, it has a crazy value play effect that Special Summons up to 2 other 'Resonator' monsters from your Deck or hand. Personality: Prickly.

Red Rising Dragon: Depicted as a dragon rising while wreathed in flames. It serves as a crucial stepping stone for summoning large numbers of Resonators. Personality: Destructive.

Hot Red Dragon Archfiend: As the manga version, it is characterized by a rougher and more destructive aura than the original. Personality: Rough.
