Q-Transformers: Mystery of Convoy Returns (キュートランスフォーマー 帰ってきたコンボイの謎 Kyūtoransufōmā Kaettekita Konboi no Nazo) is a cartoon released in support of the Q-Transformers toyline and mobile game. Episodes were broadcast on Tokyo MX, and released by animation company DLE on their YouTube and Nicovideo accounts. When each new episode was released, the previous episodes were set to "private", so that the whole series was never available all at once until its DVD/Blu-ray release.
The first season spanned 13 episodes and ran from January 6 to March 23, 2015. A second season titled Q-Transformers: The Road to Additional Popularity (キュートランスフォーマーさらなる人気者への道 Kyūtoransufōmā Saranaru Ninkimono e no Michi) followed shortly afterwards, running from July 6 to September 28.
