Timewarp Material Monsters (タイムワープ素材 (formatted as T素材 exclusively in card text) Taimuwāpu Sozai) are monsters used in the Timewarp Summoning of a Timewarp Monster. Although they are referred to in the plural sense on this page, only 1 Timewarp Material Monster is used for a Timewarp Summon at a time. Through card effects, Eon Counters are generated, and when there are enough Eon Counters available that would allow the Material Monster's original Level to reach the Level of the intended Timewarp Monster, it can be sent to the GY in order for the Timewarp Monster to be placed in a valid Monster Card Zone.
