The majestic superstar showed no sign of the calf injury that forced him out of last weekend's clash, as Geelong eased past an uncompetitive Port Adelaide outfit at AAMI Stadium on Saturday, winning by 48 points.
It was the Cats' eighth-straight win over the Power, continuing a streak that dates back to their crushing 119-point Grand Final win in 2007.
Johnson was clearly the best player on the ground with 32 possessions, nine tackles, seven inside 50s and two goal assists.
Tom Hawkins made the most of his side's continuous forward thrusts, booting an equal career-high six goals, which he had on the board by three-quarter-time.
On what was a perfect day for football in Adelaide, the Cats kicked the first eight goals and looked a class above from the opening bounce
Whereas Geelong were poised and confident under pressure the Power appeared rattled – their decision making again questionable and their execution again sub-par.
John Butcher's first shot at goal for the Power since round 15 last season missed everything from 25 metres out directly in front, as did his second.
By that point Geelong had 10 goals on the board and the game was long over.
Hawkins' decision to try and snap a fourth goal from a set shot on the slightest of angles late in the second term suggested his side had stopped taking the contest seriously.
Johnson had 18 first-half touches and a goal as well as three scoring assists in a wonderful return to football.
The Power needed an inspired third term to somehow find their way back into the game but squandered any opportunities they had to chip away at Geelong's lead.
Steven Motlop was mercurial at times, Hawkins and James Podsiadly were too strong up forward and Harry Taylor and Corey Enright rebounded the ball with ease from defence.
Podsiadly's 35-metre banana goal in the third term was indicative of just how easily the Cats were managing before they cruised through the final quarter to the easiest of victories.
