Shiro Nex

Nex is a man who attempts to alter time to switch the worlds of the living & the dead through the Ghost Train as Dwayne Winfield's abduction allows it to traverse time like the ElectroLiner. He has an obsession with Thora & cannot bring himself to do anything that he perceives would make her cry. Nex is a master of necromancy & can revive both Imagin & humans alike.

Battle with Electric King
Kamen Rider Steam Ghost Hijack Form is a very powerful Rider. Steam Ghost summons all of the past Imagins Electric King defeated during the TV show. Momotaros, Urataros, Kintaros, Ryutaros, Sieg, Garrent, & Dwayne transform into their respective riders. Steam Ghost retreats by horse as Sword Form & Liner Form give chase. As Steam Ghost stops at a battlefield, he turns around, knocking the two Electric King forms off their horses. As Steam Ghost makes his final move, Teddy arrives & stops him from doing that. Henry arrives & transforms into Kamen Rider New Electric King Strike Form. After a sword battle, Electric King Sword Form & Liner Form grab onto Steam Ghost's arms. New Electric King activates Full Charge, & while he does that, Sword Form & Liner Form activate their Full Charges, powering up their swords. The Riders defeat Steam Ghost & Nex slowly dies, while Thora stays by him saying her final words as she leaves in the Ghost Train.
