Marie is an easily angered, intimidating, and rather tomboyish girl. She has a very menacing personality. She is also shown to be quite strong, as in Tag Yer Ed she is able to defeat all three Eds in a wrestling match in less than 20 seconds. She has also been known to easily rip out Lee's armpit hair, rip the covering off of a speaker, and restrain Eddy with nothing more than a pair of underwear.

 

May is the youngest of the Kanker Sisters and is distinguished largely by her frequent snorts, buck teeth, and nasally voice. She is the quietest of the Kanker Sisters, and probably the most individualistic, as she is the only one to make an appearance without her sisters. Quite often, she stays in the background while Lee, and to a lesser extent Marie, does the talking. On occasion, she does speak up, but usually she seems content to follow her older siblings. However, when she does speak up, her voice is often loud and piercing, and this has been shown to be one of her techniques for persuading her sisters to undertake a course of action.
