- "Eternal Maximum Drive!"
- ―Finisher announcement[src]
When the Eternal Memory is placed in the weapon's Memory Slot, it initiates the Eternal Requiem (エターナルレクイエム Etānaru Rekuiemu) Maximum Drive, which generates a power wave that neutralizes an enemy Gaia Memory in sight, while the T2 version neutralizes all Gaia Memories with the exception of T2 Memories. A variation of this finisher also executes a Rider Kick to the target.
With the Eternal Memory, it can initiate the Bloody Hell Blade (ブラッディヘルブレイド Buraddi Heru Bureido) Maximum Drive, where a glowing blue sword beam is released from the weapon.
In addition to the Maximum Slots on the Lost Driver and Eternal Edge, Eternal has a series of Gaia Memory Slots on combat belts around its chest, right arm, and left leg; with the Memory Slot in the Lost Driver, a total of 27. By filling all of these Memory Slots with the T2 Gaia Memories, Eternal is powered into his Strengthening Armament (強化武装 Kyōka Busō) mode, able to absorb the X-Bicker energy to produce the Eternal Wave (エターナルウェーブ Etānaru Wēbu) green aura that he uses in his Neverending Hell (ネバーエンディングヘル Nebāendingu Heru) Maximum Drive.
