Pikachu (SSB)/Down aerial
Pikachu thrusts its head downwards whilst covering itself in electricity, electrocuting opponents that are within range. The attack deals 13% damage and average knockback, being a good KO move offstage. It is also decent for comboing floaty characters, and can tech-chase fastfallers, along with having some high shield stun which allows it to shield pressure opponents. Like most of Pikachu's other aerials, this move is fairly disjointed as well. On the downside, however, this move has a decent amount of landing lag if the move's duration is still taking place whilst Pikachu hits the ground (like Link's down aerial). This leaves Pikachu vulnerable to punishing, though the issue can easily be neglected with Z-cancelling and the move does auto-cancel as soon as its hitboxes are no longer active. The move also isn't as quick as Pikachu's other aerials, bar back aerial.
The move is better in the PAL versions of the game due to dealing 14% which allows the move to KO earlier (now being stronger than Pikachu's neutral aerial) and further improves its shield pressuring potential although this does also hurt its combo and tech-chasing potential at higher percents.
