Mahou Sentai Magiranger vs. Dekaranger was released on March 10, 2006, featuring a crossover between the Mahou Sentai Magiranger and Dekaranger cast and characters.
Jasmine/DekaYellow and Kai/MagiRed are the only ones to appear in powered up forms in original footage in this movie (SWAT Mode for DekaYellow and Legend Mode for MagiRed). While their teammates also don their respective power-ups, they only do so in stock footage for the Mecha (Zord) battle.

Senichi Enari: The cat... and the grass is talking.
Tetsudou Aira: Nonsense.
Houji Tomasu: Unbelieveable.
