Timewarp Monster

Timewarp Monsters (スペクトラムモンスター, Supekutoramu Monsutā) are new monsters created by Taylor Gorrell. Zaman is credited with the invention of these cards, though they also appear in Yu-Gi-Oh! ARC-7. Timewarp Monsters reside in the Extra Deck and are Summoned by Timewarp Summon. The color of their card frame is cyan.

Fitting their name, Timewarp Monsters are Summoned through the use the passage of time, by using Eon Counts on a monster placed in the player's Event Horizon to reach the desired Level of Timewarp Monster. This makes them the only kind of monster to require only one card to Summon.

Timewarp Monsters tend to come in two varieties: Futuristic, advanced, or evolved forms of certain kinds of monsters, or primal, simpler, devolved forms of the same kinds of monsters. The monsters they are relate to what Material Monster can be used to Timewarp Summon that monster.

Unlike all other monsters with Levels, Timewarp Monsters are capable of having both positive and negative Levels, the latter of which has only been seen on Dark Synchro Monsters up until now.
