Phil Foden wrapped up the three points after the re-start before Aguero's magical cameo saw him score twice in five minutes.
City made a superb start to a game Pep Guardiola would have been looking to get wrapped up as quickly as possible given the Champions League final is only six days away.
Two goals in the space of three minutes set the tone for the celebratory 10,000 fans inside the Etihad.
The first, on 11 minutes, came after a nice passing interchange between Jesus, Phil Foden and Riyad Mahrez which ended with the latter finding De Bruyne’s run through the middle and given the space the Everton defence allowed him, he had time to tee himself up before firing a low drive into the bottom right-hand corner
The second came on 14 minutes as City crowded out the Toffees on the halfway line allowing De Bruyne to send Jesus away on the left and he cut inside Mason Holgate before curling the ball into the same corner De Bruyne had.
It was Jesus’ 50th Premier League goal and looked to have settled the encounter until ten minutes before the break when Richarlison broke clear and Ruben Dias’ attempt to tackle the Brazilian resulted in a penalty and thankfully no more.
Mahrez almost ended the contest two minutes from half-time, sending a thunderous shot against the crossbar with Jordan Pickford well beaten.
It took the champions just eight second-half minutes to add a deserved third with good work from Jesus and Raheem Sterling presenting Foden with a chance that he tucked past Pickford and into the left corner of the net.
The moment the fans had been waiting for came on 63 minutes when Sergio Aguero came on for Mahrez to a standing ovation from al four corners of the Etihad.
Eight minutes later, our record goal-scorer was at it again, turning Holgate inside out before sending a low shot past Pickford with the outside of his boot to make it 4-0.
Incredibly, he needed just five more minutes to score again, soaring to head Fernandinho's superb cross past the keeper to make it 5-0 and in doing so overtook Wayne Rooney for the most Premier League goals with one club.
Talk about fairy-tales.
It was the perfect finale to a wonderful career with City - with a Champions League final still to come.
