Fan-Disliked Explanation: Though producer Shinichiro Shirakura explained that the Blade's helmet changes colors uncontrollably under various lighting conditions was made due to the way the helmet was made, Many fans dismissed it due to the fact that they noticed the helmet is obviously discolored since OOO, Den-O, All Riders: Let's Go Kamen Riders.
Seasonal Rot: As with Decade, Zi-O suffers from this due to a number of writing and continuity inconsistencies.
The "Over-Quartzer" movie[]
Harsher in Hindsight: Barlckxs' final attempt on shielding himself from the Heisei Riders' kicks is later seen as a metaphor of Tetsuo Kurata's controversy in 2021. It does not help the Barlckxs is modeled after Black and Black RX.
Rider Time Spin-offs[]
Ass Pull: Tezuka and Jun's homosexual relationship in Rider Time Ryuki came out of nowhere as both of them barely had any signs of romantic interaction in the original TV series.
As if his appearance isn't bad enough, the appearance of Decade Complete Form 21 has been ridiculed as "unappealing" and "cheap" in comparison to his original Complete Form, and combined with the fact that he is STILL unable to beat Ohma Zi-O with this form.
Snark Bait: The errors & inconsistences for the Zi-O VS Decade series and the treatment of Decade Complete Form 21 is considered as the lowest point of writing made by Toshiki Inoue.
