Bowser

Bowser is a Koopa from the Super Mario series. He first debuted in the game Super Mario Bros.

Moveset
Bowser has universal armor against attacks with low knockback. This is most apparent when Bowser has low damage, and it can be amplified by crouching, but not while crawling or attacking. It will decrease as Bowser starts taking more damage.

Bowser also has damage-based armor on the start-up of his tilts and smash attacks. Each move has a damage threshold: 4% for tilts, 8% for up and down smash, and 10% for forward smash. Any attack that is below the indicated percent will be armored, but an attack with a larger percent won't. For example, Bowser will armor the first 4 hits of Cloud's Side Special with full limit (which deal 3% each) during his up tilt, but the 5th hit (which deals 10%) will launch him. However, Bowser's forward smash will be able to armor even the last hit of said Side Special.

Bowser can double jump and crawl.
