On Stage 1-3, pick any character you want (The Dash character will make it even easier). Once the stage starts, instead of killing enemies, just circle around the edges stunning cubes that get into your way and let the screen fill up with enemies. After about a minute or 2-3 waves of spawns, grab the laser at the bottom of the screen and you should get 130 kills just from what is on the screen alone. Very easy way to get the achievement.
