Kamen Rider W: Hidari Shoutarou's Hardboiled Delusion Diary (2009-10)

These shorts were included as extras on W's myriad DVD releases. Because the plot points that are mentioned in each delusion don't always line up with the Dopant suits that appear, I recommend viewing these post-series for the sake of ease. If you absolutely insist on risking it, just don't watch number 11. It contains a catastrophic spoiler for the endgame. You've been warned.

12 shorts, ranging from 3-5 minutes, apiece.

Kamen Rider Kuuga (2000-01)

Net Edition: Kamen Rider Backwards-Kiva:Queen of Hell's Castle (2008)

A rare moment of Sosuke being nice to Bomper.

You should watch them before seeing Kiva's dedicated movie, if you are interested.

Kamen Rider W Forever: A to Z Net Movies— 26 Rapid-Fire Laughs (2010)

Kamen Rider Agito Special: A New Transformation (2001)

This was aired between episodes 35 and 36 and you’ll want to watch it then, too, as this conveys all of the emotional significance behind Agito’s final form. The debut of it in the show itself (in episode 37) assumes you’ve seen this as there’s not much in the way of specific explanation. It's worth noting that G3 Mild appears here.

Kamen Rider Kiva (2008-09)

Imagin Sentai Kamen Rider Den-O (2007-08)

Kamen Rider Blade (2004-05)

Kamen Rider Agito (2001-02)

 

Kamen Rider W (2009-10)

I'll leave this bit, here, out of respect to the friends who helped me write it:

The purple and green of W’s base form speaks to the fundamental theme of the series: one does not exist without the other, because they exist within one another. Philip’s sins mirror Shoutarou’s and their strengths and weaknesses complement and compensate for one another’s. The concepts of compassion, justice, human frailty, fear, loss, and community are examined, but far eclipsing of those is the exploration of the true nature of family.
