- Ghost joins the steadily-growing list of Riders who are not red but gain a red form change to rectify that, like Agito, W, Fourze and Gaim.
- Takeru's summoning of the Ghost Driver is similar to how Kuuga summons the Arcle. And Robin Damashi, the green form armed with a bowgun, is pretty much Kuuga Pegasus Form.
- The driver sounds follow the standardised-jingle-into-unique-Transformation Sequence-or-Finishing Move system started by Kamen Rider Wizard.
- Ghost's green form lets him duplicate himself? That sounds familiar...
- Turns out the Mysterious Backer of the Ganma was secretly working with Tenkuji Ryu on something big, which may or may not have killed him, just like a certain Utahoshi Rokuro.
- Once Takeru gets to space, he feels the need to hold his arms up and shout Uchuu Ni KITAA!
- Toucon Boost Damashi is very similar to Kuuga's Rising Forms, simply being an upgraded version of his base form. And can allow upgraded versions of his other base forms to be used as well.
- Heroic Eyecons suddenly have the ability to possess people as well, resulting in a new eye color (though they all turn blue regardless of Eyecon color, going by Himiko).
- In ep. 35, Igor uses the Grimm Eyecon to mutate the Dreamworld into Helheim.
