* The Neon Genesis Middle Schoolers ''need'' to bring Junk to the mountains for Gridman to transform. Back in the last episode of ''Superhuman Samurai Syber-Squad'', Team Samurai (minus Sam who was on a date) went on a hike and they brought along their computer in case of Megavirus Monster attack, which did happen as Tanker becomes Servo for that battle.

* Of course, there's the fact that the four S' in the title seem to stand for '''S'''uperhuman '''S'''amurai '''S'''yber '''S'''quad.

* On top of that, the MenInBlack / Assist Weapons Quartet, which comprises of Samurai Calibur, Borr, and Vit are named after the ''Series/SuperhumanSamuraiSyberSquad'' arsenal programs Samurai Sword, Borr, and Vitor. BigGuy Max is the odd one out until he transforms into the Battle Tracto Max with Tanker Cannons.

* The alien city that was above the sky is, in fact, the Computer World from ''Denkou Choujin'', aka. Digital World in ''Superhuman Samurai Syber-Squad''.
