The "Majestic" Synchro Monsters return to the Extra Deck during the End Phase and Special Summon the corresponding base Dragon back from the Graveyard. Their effects are similar to their "Signer Dragon's" counterpart, except they are more powerful; they can also negate the effect of an opponent's face-up monster and get an advantage from the negated card until the End Phase.
In the anime, before "Majestic Dragon" is drawn, the Dragon's Birthmarks of the five Signers form the complete Seal of the Crimson Dragon on the user's back. When Summoned in the anime, the user of the dragon will be carried in its body for as long as it remains on the field. These dragons have been shown to be extremely large in size, dwarfing their base "Signer Dragon" counterparts. They appear to glow, and they attack by flying straight through their target. The Crimson Dragon has previously used "Majestic Star Dragon" to gain physical form, and when the same dragon was Summoned against Team Ragnarok, Halldor called it an "incarnation" of the Crimson Dragon. With the exception of Yusei's Turbo Duel against Halldor, every Duel involving a Majestic Synchro Monster had the user inside the monster and was used to deal the finishing blow in a Duel.
