Zach is a Mobian fox from Mobius. He is very smart — his intelligence is equal to Dexter and Mandark's.
In FusionFall, Mobius was invaded by Fuse and Zach and his wife got away to earth. Zach put his wife somewhere safe and they split up. Dexter noticed Zach's intelligence and asked Zach to help him in the war by fighting and helping with Nano enhancement. Zach accepted and went to City Hall with Bubbles and the Mayor. Bubbles calls him cute for a talking fox and Zach says that he’s not cute.
In the Future, Zach is nowhere to be found, though his wife is. He has a hologram in Hero Square for helping Dexter with Nano enhancement. His wife mentions he could just have flown away with his jet boots, though he said that the fuel was empty.
In the past, Zach is with Bubbles and the Mayor, His missions consist of helping with Nano enhancement, getting back his tech from the Fusion Octabots, or helping Flapjack in finding Bubbie by finding enough batteries to charge up his animal tracker.
