Thanks to Hasbro Fan Friday, we found out we are getting four more Metallic Armor Rangers in Lightning Collection to join Kat/Pink Ranger. Each comes with a zeo crystal. Also a Red Sentry from the Boom Comics "Shattered Grid" arc.
Billy and Adam
Billy remained on the show until Zeo. He also stopped wearing the glasses because the actor David Yost had problems with the glasses they use.
Aisha and Rocky
Aisha seems to have her hair from the end of Season 2.
Tyrannosaurus Sentry, no face. In the comic, Skull was one of the sentries.
Jordon Fite has been revealed to be Ion/Gold Ranger in Dino Fury.
