Abilities and Powers
Each member of the WCI31 is a well renowned chef within Totto Land's borders.

Charlotte Family
As residents of Totto Land and Whole Cake Island in particular, the WCI31 are submissive to the Charlotte Family and to the Big Mom Pirates. They even follow orders of Vinsmoke Sanji, who they believe is a very recent member of the family.

Charlotte Pudding
Being part of the Charlotte Family, the WCI31 follows Pudding's orders without question, as shown by the fact that they entered the "Sweets Factory" one at a time without her giving them an explanation.

Charlotte Chiffon
Being part of the Charlotte Family, the WCI31 follows Chiffon's orders. When they were baffled by Sanji's tight schedule, Chiffon yelled at them to get back to work which they fearfully complied.

Streusen
The WCI31 highly respect the Big Mom Pirates head chef, and were amazed that someone was able to decipher his secret recipes in a moments notice.

Vinsmoke Sanji
Despite hearing rumors about Sanji's culinary skill, the WCI31 were amazed when witnessing them in person.

The commonly refer to him as "Mr. Husband" believing him and Charlotte Pudding are newlywed.

Whole Cake Island Arc
The WCI31 gathered at Chocolat Town on Cacao Island on the request of Charlotte Pudding and were enlisted to make a replacement wedding cake to satiate Big Mom's craving for wedding cake.

Under Pudding orders, they entered the "Sweets Factory" one at a time, and each chef was submitted to Pudding's memory alterations so they would follow Vinsmoke Sanji's recipe.

Trivia

 * While not confirmed to be a part of the group, Streusen as well as other chefs seen so far on Whole Cake Island, and the disguised Fire Tank Pirates, wear identical outfits to those of the WCI31.
 * The group number (31) might be a reference to Baskin-Robbins' 31 flavors of ice cream. In Japan, it is called "BR 31 Ice Cream", fitting several food themed names of Totto Land's residents.
