When Rose Tyler attempted to get the TARDIS to start to reunite her with the Ninth Doctor on the Satellite Five in the year 200.100, she forced open the Heart of the TARDIS from the TARDIS console, which caused Vortex energy to flow into her via her eyes, which gained a golden glow to them, and created the Bad Wolf, which destroyed all the Daleks that were present and revived Jack Harkness. The Doctor then noted it would kill Rose and was forced to sacrifice himself by absorbing all the energy into himself, and released it back into the TARDIS. (TV: Bad Wolf)

The Slitheen Blon Fel-Fotch Passameer-Day Slitheen, disguised as Margaret Blaine, was forced to look into the Heart of the TARDIS, into the Vortex energy, and as a result was relieved and regressed into an egg. (TV: Boom Town)

When the Flux was approaching the TARDIS, the Thirteenth Doctor unleashed vortex energy from the TARDIS console at it, however the energy appeared to have no effect. (TV: The Halloween Apocalypse) The collision between the energy and the Flux caused the TARDIS and its occupants to fall through time, intially sending them all to the Crimea in 1855 and subsequently sending Yaz to the planet Time and Dan to Liverpool in 2021.
