Gideon (Earth-Prime)/Time Vault

"It has been an honor working with you, Barry Allen. Farewell."

- Gideon's last words in an erased timeline

Gideon is an interactive artificial consciousness used by Team Flash.

Mobilized
In 2020, Barry Allen upgraded Gideon during his search for changes caused by the Crisis. Chester P. Runk then entered, assisting the upgrades. However, Chester's tampering caused Gideon to trap Barry's mind in Grodd's. The team later brought Barry back to his own mind.

Death of the Speed Force
Later, Gideon was once activated in the Time Vault when Barry attempted to use the Tachyon Prototype to enter the Speed Force before its ultimate death.

Diagnosis on Barry Allen
Months later, Barry Allen's mind was possessed by all Harrison Wellses of the Original Multiverse. Chester then used Gideon to diagnose Barry Allen's body status during the possession, and determined that without his speed healing, he would die immediately.

Distant Future
In 2049, Gideon became the assistant to XS and Impulse, acting as a guide to both while they are on the field.
