Dutchess is a minor character in the Oscar the White Tiger series. She is a pink poodle and one of the earlier characters in the series. She lives in Ireland and is very posh, and she also seems to think highly of herself.
Dutchess appears in All Star Smashers as a Support Spirit, as an Ace class, where you must fight Steve Burns, Maxwell and Lily at Plastination as 3 characters of your choosing to obtain her. When fighting Steve, Maxwell and Lily, the battle will be a 3 on 3 battle, palettes will depend on the team's colour, and teammates will temporarily change colour and turn their back on you.
- Completing Dutchess' Spirit Battle will also obtain Neil Buchanan.
