The Bionic Student Vanishing is an event that took place during February 3, 2016 (although this date may not be accurate). During training, all of the bionic students suddenly disappear for unknown reasons, and Davenport as well as the rest of his family (excluding Tasha) go to Giselle's lab at her company in order to save them.

This serves as the return of Marcus Davenport, who was absent in Season 3 and most of Bionic Island but is constantly mentioned. This is also an event that serves as a prequel to Lab Rats: Elite Force.
