Pokémon Go developer Niantic has now officially announced its overhaul of the Mega Evolution mechanic, which was previously leaked through datamined game files.
As expected, the changes go a long way to answering fan criticism of the way Pokémon Go has handled Mega Evolution since it was introduced in August 2020 – in particular, adding the ability to re-Mega Evolve a creature without energy cost after it has been Mega Evolved once.
Players in Australia and New Zealand can access the new system now, with a global rollout expected shortly. (The game’s next Mega Pokémon release is due this Friday, so we’d expect before then.)

Mega Evolution can now be a one-time cost, though there is a rest period where your Pokémon is fatigued where you’ll need to wait (or invest in Mega Energy to skip it). The exact wait time depends on what Mega Level your Pokémon now is – another new feature.
