The Playing Cards.

They are playing cards with a human head, arms and legs. They are loyal servants as well as guards for the Queen of Hearts. They mainly carry spears with the tip shaped as a heart. Alice first meets three cards at the Queen's castle painting white roses red. One of them explains that they accidentally planted white roses, and because the Queen hates white roses they have to paint them red or the Queen will behead them. After the Queen arrives, she finds white roses and orders the execution of all three. Alice declares that they "shan't be beheaded" and hides them in a flowerpot. Their would-be executioners spend a minute or two looking for them before giving up. When Alice joins a game of croquet with the Queen and the other playing cards, the card soldiers act as arches. They have to leave being arches every time the Queen has an executioner drag the victim away. They also appear in the trial where the Knave of Hearts is accused for stealing the Queen's tarts.

The Playing Cards also appear in the 1951 Alice in Wonderland animated film as playing cards with masks shaped like card symbols that match their spears and gloves. They also march as they chase Alice even over the hedges of the labyrinth. They are played by The Mellomen, Don Barclay and Larry Grey. The Playing Cards also appeared in House of Mouse voiced by Corey Burton.

They appear in the 2010 film as playing cards with red armor that covers their body, masks and shoulder plates shaped like hearts, and spears with tips shaped like hearts. There are no cards of spades, clovers or diamonds, for only cards of hearts appear in this film. They are called "Red Knights" and serve the Red Queen.

They appear in the video game, American McGee's Alice where they carry axes and bow guns.

In the novel The Looking Glass Wars, they appear as robots with their outer layer shaped as cards and spears. They can fly while in card form and can walk as well as spear in soldier form. They work for Queen Redd, the main antagonist of the series.

In the otome game Alice in the Country of Hearts (Heart no Kuni no Alice), they are humans with card-marked uniforms that have different numbers for each servant and British hats. There appear to be female versions of these as well.
