Man, it's been so long since I've drew a mecha.
Jackal79 (J-79). A sentient robot jackal that's an obsolete model. He was made for battle and for tactical missions. Unlike the previous robots, he's capable to learn and adapt to new things, and he's seen his fellow robots that gone obsolete were scrapped, which he feared it might happen to him someday.
What Jackal79 feared came true; They built a new robot with better abilities than him. He knew he was gonna get scrapped for being an obsolete model, so he refused. The new model was then ordered to take him out, but Jackal79's strong will to live managed to destroy the new model with one swift blow. He then escapes and tries to survive in an unforgiving world. Nobody knows what happened to Jackal79's whereabouts.
