Kamen Rider Stronger's sidekick, Electro Wave Human Tackle (Denpa Ningen Takkuru), which died on the original series, will make her return in the upcoming Kamen Rider x Kamen Rider W and Decade: Movie Taisen 2010 on December 2009. This era's Tackle will be played by Alice Hirosue which is then 14 years old. But most fans said that she doesn't look like one. XD

Take a look at this video regarding the original Tackle:



I have been looking for the clip when she died but I don't have any luck on seeing that on YouTube.

And here's some new rumors regarding the upcoming movie:

• Tackle's secret is that she has already been killed by Hacchi Onna. Tackle is actually some sort of universal overseer, who begins to observe Tsukasa after he defeats the riders and becomes the "Devil's Soldier."
• Yuuske will succeed in killing Tsukasa, probably in his demon state. However, the memories of Yuuske, Natsuki, and Daiki will resurrect him
• After their fight with Super Shocker, Neo Lifeform Doras will escape into another world. They follow suit. That world is the World of Double.
• Doras and the Dummy Dopant will fuse into a final villain to fight. At the end of the film, the disappeared rider worlds are brought back into existence
• The movie, as far as now, will flow as follows:
  • 30 minutes of Decade, leads into Double Begins Night
  • 30 minutes of Double, at the end of which Decade appears, big team up fight
    
  • Rumor has it that Doras, from the Decade movie, and a "Dummy Dopant" from Double will fuse into one monster for the end of the film.
