He eventually is turned back into himself again thanks to the Overdrive Rangers and returns to his mission. When the Rangers cross paths with the Fearcats, they also cross paths with Tyzonn and asks him to join them. At first he is hesitant but eventually he agrees and becomes the Mercury Ranger. Tyzonn is shown to be interested in Earth culture when he asks Rose a few question on how she spends her day. When all the Jewels of the Corona Aurora are found, Tyzonn is reunited with his fiancee Vella and they return to Mercuria.
The Rescue Runners are the personal zords of the Mercury Ranger. The Rescue Runners can combine to form the Flashpoint Megazord.
