On the upcoming Kamen Rider W Movie, part of the story is that W will be facing the Dopant forms of their respective memories. Yep, they will be facing, all their memories minus Joker. Here's a look on each of their memories in Dopant form. So far, I am loving Cyclone, Trigger and Heat Dopants respective designs.
This. Is. Epic. W is fighting both Heat and Metal Dopants while in HeatMetal!
So Eternal is leading the army of Dopants based on W's Memories.
On the top left is Accel Trial fighting the Trigger Dopant, below is a battle scene with W HeatMetal Vs. Heat and Metal Dopants and on the right is W fighting Luna Dopant.
