Reformatting

Reformatting is a term for the wholesale upgrading of a Cybertronian into a new form granting them new power and new altmodes after scanning a vehicle or an animal.

On Earth, many Autobots and Decepticons have all reformatted their appearances.

"Rebellion"
When Optimus Prime was on the verge of death, Smokescreen used the last of the energy remaining in the Forge of Solus Prime to save him, healing Optimus's grievous wounds and granting him a newer, more powerful body.

"Predacons Rising"
Needing a vessel in order to destroy Cybertron, Unicron revived Megatron's corpse and upgraded it with special armor.

"The Buzz on Windblade"
A thousand years before the present day, Primus selected Windblade to travel to Earth for a future crisis. To prepare her for the task, he granted her a new, more combat-focused chassis.

"Battlegrounds, Part 1"
With Megatronus' arrival to Earth imminent, Optimus Prime convinced the other original Primes to forgo additional training and send him to Earth immediately to deal with the threat. The Primes shared portions of their power with Optimus, granting him a new, more battle-ready body.
