Bowser (SSBU)/Forward tilt
Bowser does a swung backhanded punch with his arm slightly bent. The punch can be angled up or down, but doing so does not affect damage or knockback. Has damaged-based armor (frames 7-9) and intangibility on his arm (frames 10-14). The downward-angled version can very reliably 2-frame most recoveries, and can KO most characters at around 90%.
