Smack Studio / Specter Knight
Specter Knight is, at his core, an all-rounder not too dissimilar to Shovel Knight. The difference comes in the trade of survivabilty for increased mobility and power. Specter Knight can navigate the stage with ease, and has strong attacks that can kill easily when used correctly. However, his defense is sub-par at best and he can struggle when disadvantaged.
Specter Knight's specials, while not character-defining, all boost some parts of his gameplay. Chronus Coin is a fast but limited projectile that enables and extends many combos. Throwing Sickle is a weak boomerang projectile with good range and some combo usage on the return. Hover Plume is a fantastic recovery and mobility tool, with the ability to be cancel into any other attack. Finally, Skeletal Sentry gives a supporting barrage of projectiles to cover SK's approach or generally harass long ranged opponents.
Specter Knight's tilt attacks, especially up tilt and down tilt, are great combo tools that lead into many other attacks. Specter Knight also has great kill options, with forward strong, up strong, up air, and forward throw all reliably killing opponents.
