Home-Run Combo

Sandbag currently has an unnamed Final Smash.

Overview
When triggered, Sandbag will suck up the character nearest to him, and then blast off like a rocket towards the Home-Run Contest stadium, then, creates a "negative zone", that stops time, and combos the opponent, with two attacks (up tilt, and back aerial, respectively). He then grabs a Home-Run Bat from inside himself, winks, and proceeds to hit the opponent very hard, launching them "out of the park" to the point the Home-Run Contest counter get broken.

Origin
Sandbag's Final Smash is the crux of the joke behind Sandbag's character, in that he himself is usually the target in Home-Run Contest and is now returning the favor to those responsible.

The highest scores in the mode are attainable by performing steady combos within the confines of the small platform, which Sandbag does automatically. The method how he goes about it, however, is an external reference to JoJo's Bizarre Adventure; specifically, to the character Dio Brando and his own ability to stop time, marked in the series by inverted colors. Additionally, the animation that plays just before smashing his opponent is an external reference to Fire Emblem: Awakening; specifically, to the near-identical animation that plays when a character gets a Critical Hit.

Trivia

 * As of version 1.0.2 Beta, the animation uses a very old Home-Run Bat texture, with two red lines and a red circular logo resembling a target, whereas the Home-Run Bat in v0.9 used a different texture, with two brown lines and a different logo, also brown.
