Tenkai Reversal Inductor

The Reversal Inductor (Japanese: 拘束装置, Kōsoku Sōchi, Eng. Translated: Restraint Device, or Restraint System, Korean: 구속 장치, Gusok Jangchi), also known as the Energy Conversion Device (Japanese: エナジー変換装置, Enajī Henkan Sōchi, Korean: 에너지 변환 장치, Eneoji Byeonhwan Jangchi), is a device that Dromus created in episodes before "Vilius Unleashed", where it was finally used to capture the Tenkai Dragon from the Knights and the Corekai. It takes Tenkai Energy from the Tenkai Dragon that can be used to make Vilius' army stronger, which was first demonstrated in "Robofusion!". The Tenkai Reversal Inductor has been used to grant Granox and Slyger the ability of Titan Fusion and improved their Robofusion. It was later destroyed by the Dark Tenkai Dragon in "The Dark Unlock".

In the Series
The Reversal Inductor was first seen in "Vilius Unleashed", where it served as a cage in order for the Corrupted to easily capture the Tenkai Dragon.

In "Oh No, I Didn't", Dromus was explaining to Vilius that he has beein doing some tests with the Inductor and that a few more adjustments will make it possible to use.

In "Robofusion!", Dromus explains to Vilius that the Inductor's energy extraction process is not ready yet. Later, the Inductor becomes posible to extract energy, which is used to help make Granox and Slyger's Robofusion stronger, but was destroyed by the Knights in Titan Mode.

In "Extreme Titan", Dromus uses the Dragon's energy from the Inductor to give Titan Fusion to Slyger, which he used to fuse with a Sky Griffin, but was destroyed by Bravenwolf and Valorn's Titan Fusion.

In "Double Crossed", Dromus uses the Dragon's energy to make Hos' Titan Mode more stonger and larger, but was destroyed by Bravenwolf and Tributon's Titan Fusion.

In "Checkmate", Dromus uses the Dragon's energy from the Inductor to give Titan Fusion to Granox, which he used to fuse with a War Stallion, however, he wasn't destroyed by the Knights. Vilius uses the Dragon's energy from the Inductor to levitate his whole army to the Guardians Sanctuary.

In "The Dark Unlock", Vilius travels close to the inductor and uses the Black Key to awaken the evil side of the Tenkai Dragon. He commands the Dragon to destroy Bravenwolf, but ends up breaking his fortress, including the Inductor, which he said that he didn't care.

In "A New Knight", Vilius uses all of the remaining Dragon's energy from the Inductor to make him highly power and gigantic, but was defeated and destroyed by the Knights and Dromus in Phoenix Mode.
