Pikachu (SSB)/Up tilt
Pikachu swings its tail upwards dealing 11% damage. While not superior to Kirby's up tilt due to its slower speed and lower power, it is an extremely useful move for combos and one of Pikachu's great combo starters. Pikachu can juggle the opponent many times with this move, from low percentages up until mid or mid-high percentages (depending on who the opponent is), in addition of it being versatile as it can be followed up by virtually any move it wants (usually another up tilt for shield pressure, a grab, or a up smash, possibly followed by a Thunderspike at high percentages).
Overall, one of Pikachu's best moves due to its said combo ability, some range, and a large disjointed hitbox. In the PAL versions, the move has slightly higher base knockback making it an even more reliable combo tool at lower percents.
