Rescue Force Sigma-17 is a small team of Rescue Bots. These team of Autobots were once part of a larger Rescue Bot sub-group that left Cybertron some time before the Great Exodus. Now in the post-Great Exodus era, they may be currently the last Rescue Bots in existence.

The Rescue Force Sigma-17 team were placed in stasis for unknown reasons and their ship have wandered aimlessly through space for an unspecified length of time until it picked up Optimus Prime's message to travel to Earth. After they arrived in an unknown area, Optimus Prime have repurposed them to be Griffin Rock's Rescue Bots and gave them new alt-modes.
