Yeah, Gridman had a similar antisocial loner making the monsters for petty reasons (case in point: he once reprogrammed a hairdryer to turn anyone using it into a punk purely because the girl he was crushing on was nice to people other than him). The main thing that sets him apart is that he had some moments wherein he’d reconsider his plans, only to go through them with brainwashing.

And today’s notes section.

* Rikka theorises that Gridman was responsible for repairing the city. While the real cause turns out to be different, that’s exactly what happened in the old series, wherein Gridman would repair the damage following every battle with his Fixer Beam.
* Something I missed last time, but Gridman’s blue colour scheme within Junk calls to mind the jumpsuit Naoto wore during the original series’ transformation stock footage.
* Samurai Calibur is based off Gridman Sword, a weapon that was created by Compoid and Anosillus after saving the latter monster from Takeshi Todo's brainwashing. His Axe Mode is a throwback to the Gridman Sword's alternate mode, Thunder Axe.
* His name is based off the Samurai Sword, the name for the Gridman Sword in Superhuman Samurai Syber-Squad.
* Since the rest of his teammates references both Team Samurai and their Assist Weapons, Samurai・Calibur's name sounds similar to Sam Collins.
* The actor voicing him in Japanese, Ryosuke Takahashi, is better known as the lead character Takuto Ando/Lio-Sazer in Chousei Kantai Sazer-X, a Tokusatsu series from 2006 by Konami and Toho Studios meant to cash in on the success of Super Sentai. It was the third in a trilogy after Chouseishin Gransazer and Genseishin Justirisers and included Gokaiger’s Gaku Shindo (Barizorg) and Kamen Rider OOO’s Ryosuke Miura (Ankh/Shingo) in supporting roles.
* So how did Samurai become Gridman Calibur? He shouts the Access Code. In the original series, Gridman cannot exit Junk unless the trio enters the Access Code "GRIDMAN". In episode 31, entering the wrong code (GRIDOMAN) would be ineffective.
* And Yuta does his predecessor’s pose and declaration of “Access Flash!” Comparison here.
