A mobile particle cannon from the Plarail Shinkalion CW toyline, the ERDA Positron Rifle belongs to the crossover tying the Shinkalion: Change the World series to Evangelion. Built from NERV combat data, it trades raw firepower for freedom of movement and can merge with a Shinkalion for battle.
Cataloged in Japanese as the Evolution Railway Development Agency Self-Propelled 460mm Positron Rifle, this vehicle belongs to the Plarail Shinkalion CW toy lineup, which adapts the Shinkalion: Change the World television series. It stands among the ERDA vehicles and represents one of several crossover machines linking the Shinkalion and Evangelion franchises.
The agency engineered this rolling cannon after studying technical records obtained from NERV. Compared with the positron weapon fired during the Operation Yashima engagement, its output is considerably lower; the tradeoff is mobility, since the rifle drives itself around the battlefield rather than sitting fixed in place.
Its signature gimmick is combination: docking with the Shinkalion 500 TYPE EVA (CW) produces the Shinkalion 500 TYPE EVA Positron Form.
The Evolution Railway Development Agency operates the rifle, and the Shinkalion 500 TYPE EVA (CW) serves as its combination partner. TAKARA TOMY produced the physical toy, selling the Plarail Shinkalion CW 500 TYPE EVA Positron Form set from 06 December 2025 at ¥7,920 with tax; the box bundles the base Shinkalion, the rifle, and the combined Positron Form.
Its silhouette pays homage to the 2nd Experimental High Power Self-Propelled 460mm Positron Cannon seen in the film Evangelion: 1.0 You Are (Not) Alone.

Naruto vs Luffy with the twist nobody asked for: Luffy tickled Hinata on date night, and she kind of liked it. We break down the whole fight and commit to a winner....

There are no women on Namek. That isn't an oversight, it's the biology. Why we handed Piccolo the one thing his own species rules out, and why it had to be trap soul....
