I made this suggestion because I feel that his dash attack has a lot to be desired. At low percentages, it barely phases the opponent, and at high percentages, it knocks the opponent too much horizontal distance for me to follow up on it. I always found myself getting punished in melee when I used pikachu's dash attack, and in project M, it doesn't really feel any different from melee. Maybe I haven't tried his dash attack in a while, so it might have changed. Look at fox, falco, and peach's dash attacks. They follow up combos, and they are useful unless shielded. I think that if I were to use pikachu's dash attack animation/hit boxes and change the damage and trajectory, I would want pikachu's attack to send the opponent farther back horizontally (maybe 15-20% more powerful than it is now) at the start, and when pikachu hits the ground, his attack could send the opponent at a vertical distance for combos. Nothing too powerful, just something Pikachu could use to bump him up a little bit.
