LEFT (beige Glaug with blue effects): DA-24 Waruder Suit "Stang" from Diaclone Reboot. He's the guy subjected to a techno-organic reimagining of the other two, and is a preassembled figure whereas the other two are model kits.
CENTER (Walker Gallier skipped leg day): Vintage Waruder Suit (Swamp Type) made by Nitto to accompany Tomy's 80s Diaclone line.
RIGHT (Diet-Battles): Vintage Waruder Suit (Arithuc), also by Nitto.
