The achievement is quite simple, it is enough that at the start of the game you start collecting the blue stars that are on the map to fill the superstar mode bar.
As a recommendation, I suggest that they learn to fight and defend themselves so that they do not have problems when performing the technique. Superstar mode is activated with
+ 
when the bar is full, but keep in mind that this lasts a few seconds so pressing 
towards an opponent will do your super move and if you are lucky you will be able to knock out your opponent to receive the achievement.
I hope my guide is useful to you and thanks for reading.
