After an accident with Justin puts him into comatose, Aelita temporarily downloads his mind into a protoform, creating the new Maximal, K-9. An infiltrator unit, K-9 has Justin's mind and courage, as well as the combat readiness of a Maximal.
Last Chance at LoveEdit
His robot form is similar to Wolfang, except he was white, light blue, had light green eyes, and what looked like details of a German Shepherd for his beast mode.
His beast form is a German Shepherd and later becomes a mechanical Transmetal German Shepherd.
His human form looked exactly like Justin.
His Vehicle mode is the same as Wolfang.
- The idea for K-9 came from the Transformers G1 episode, Autobot Spike, in which Spike's mind is transferred into an Autobot Body made up of spare parts.
- The revival of K-9 from Aeltia's energies, was inspired by a chapter of the manga, Gantz. In which Reika made a copy of Kei, because she couldn't let go of her feelings for him, and truly loved him.
