Initially, Bass had three different costumes, with two default costumes and one unlockable costume. However, with the release of the downloadable content, Bass now has four costumes overall, with one different DLC costume.
For his costumes, Bass has two brand new costumes, though they are both redesigns of previous costumes in the series.
|Costume 1 - Grey vest with a fur collar, matching pants, leather boots, a pair of gloves, sunglasses, and broken shackles around his wrists.
(Originally his first costume from Dead or Alive 4.)
|Costume 2 - Metal briefs with a belt and suspenders that have feathers, metal bands around his thighs, black socks, armored boots with feathers, a pair of gloves, and spiked arm-guards and armbands on his biceps.||Default|
|Costume 3 - Metal briefs with a belt and suspenders that have spikes, metal bands around his thighs, black socks, armored boots, a pair of gloves, and spiked arm-guards and armbands on his biceps.
(This costume is a redesign of his fifth costume from DOA2: Hard*Core.)
