Terry (SSBU)/Dash attack
Terry executes a shoulder block dubbed "Power Charge", a staple move in his games. The move lasts for an exceptionally long time with a disjointed hitbox, making it relatively easy to connect. The strong hit has a good amount of active frames, and has good KO potential, making it a very threatening whiff punish considering the distance. It also crosses up shield consistently, which combined with the distance covered, makes the -18 shield advantage less of an issue than it seems.
However, dash attack is often overshadowed by Terry's other burst options, especially his command specials such as Crack Shoot. These can be combo'd into with relative ease, have stronger situations and/or kill power after use, and better situations on shield (sometimes even shield breaks). However, the sheer hitbox activity and general safety of the move gives it strong utility as a burst option and whiff punish tool.
