The character sheet for the webcomic Collar 6. This page shows the various characters and the tropes related to them.

Sixx, aka Michelle O'Carroll

Sixx is a hotel tycoon and Dominatrix, and the former slave of the now-enslaved Mistress Trina. She has slaves all over the world, but has a primary household in which the other main characters serve her. Sixx is actually a title, her real name is Michelle. As part of her plan to win the spanking contest with Butterfly Sixx temporarily gave up her title, which was assumed by Laura.

Laura de Silva

She temporarily assumed the mantel of Mistress Sixx before giving it back to Michelle following the contest. Was being held hostage by Evita Kappel until she was rescued.


The maid in Sixx’s primary household, she is in love with Sixx. She is initially very hostile towards Laura, but eventually comes to accept her when Laura insists that they share the position of “personal slave.”
