Out of the Blue - S1.E20

Impmon is defeated by Indramon; Indramon then seems to self destruct willingly. Mr. Wong is introduced to the Juggernaut program and is asked to help destroy the Digimon. Indramon rematerializes, and the Tamers commence battle. The Tamers prove no match for Indramon and he isn't even scratched by theirs or the military's attacks. In a desperate move, Takato tries the Blue Card his friend Kazu made for him and Growlmon digivolves to WarGrowlmon again. WarGrowlmon easily destroys Indramon leaving Kazu very pleased with himself.
