Toei English Mistakes
As great as the creations by Toei are, they're only human. Sometimes they make mistakes. While material from official sources should always be considered, they should never be regarded as sacrosanct.
Kamen Rider Faiz
Accel Form - Axel Form
Kamen Rider Blade
Red Rhombus - On Garren's profile page, his bike is spelled Red Rambass.
Kamen Rider Kabuto
Worm - For a few weeks, the official webpage spelled it as Warm.
Kamen Rider Kiva
For the first couple of weeks, the official website referred to the Fangire as "Fangaia" and "Vankire"
Kamen Rider Decade
Stuff on Decade's belt effect is spelled wrong.
Kamen Rider OOO
Ankh - For a while, the official page spelled it as "Unkh", completely missing the reference to the symbol of life.
Kamen Rider Fourze
Rocket - Roket
Elec - Elek
Radar - Rader
Rabbit Hutch - Spelling on the base is "Rabbit Hatch". In Japanese hatch/hutch are exactly the same pronunciation. Rabbits, however, live in hutches. Nor is their base in a hatch.
Hikounin Sentai AkibaRanger
Kozukozu - Kozkoz in the picture file. The spelling in the image is correct though. A lot of the webpage background stuff is simplified or incorrect, the only reason this is mentioned is because of how prolific this particular mistake has become among the English community.
