The Decade Bazooka, is a firearm weapon of Decade's that is only seen in the Kamen Rider Decade Super Adventure DVD. To tie in with the DVD, the Decade Bazooka is constructed from cardboard punchouts and glue by Yusuke Onodera, much like prizes given out with issues of the TV-Kun magazine. When wielded by Decade, it grows to a large weapon and can fire an extremely powerful blast of energy.
