In 1991 figures were released on four main styles of cardbacks: 22-Backs (Style A), 22-Backs (Style A) with pink Combat Pay/Magnet promotion stickers, 22-Backs (Style B), and 22-Backs (Style B) with Universal Studios promotion stickers. Combat Pay promotion stickers were also available in 1990. The 1990 Combat Pay version was green, as opposed to this year's version which was pink and also included the magnets promotion.
Both the Style A and the Style B cardbacks are 22-Backs, but there is a variation between the two styles. Style A cards feature Dusty & Sandstorm in the top left picture on the back, whereas the Style B cards feature Grunt in the top left picture. For the Style B cards Hasbro removed the last six images of the Style A format, moved all the others down, and added six new images in the top row. Other than the top row the images are identical in sequence on both styles of cards.
Sub-Groups and miscellaneous figures available in 1991 include Eco-Warriors, Eco-Warriors with Universal Studios promotion stickers, and Super Sonic Fighters.
Both Series Nine (1990) and Series Ten (1991) figures were available this year.
