First Appearance: It's Walky! 27 November 2001
Squadron(s): 48

Marcie is one of the members of SEMME's sexiest squadron, Squadron 48. Any resemblance between her and other comic characters of the same name is purely coincidental.

Spoiler warning!
Plot and/or ending details follow.

It's Walky![]

Marcie and her fellow squadmates were assigned to train Joe Rosenthal as a SEMME agent following his recruitment into the organization, although their definition of "training" was somewhat debatable.[1]

When the JFO attacked SEMME for the first time, Squadron 48 was among the teams caught in the line of fire, and chose to pursue the JFO after Grace was hit with the mindwiper.

Marcie was one of the only members of Squad 48 to survive the JFO's second and final attack on SEMME, the other being Sierra.

After SEMME[]

When SEMME was shut down after the Martian invasion, Marcie was assigned to Jason Chesterfield's command to track down Monkey Master. Some years later, she and Travis Amir were among the agents dispatched to investigate Head Alien II's secret base in the ruins of SEMME HQ in Denver, and barely escaped death at the hands of HA2's army of brainwashed "future kids". At some point, she also accompanied Jason in his pursuit of the Giant Mutant Frosted Honey Bun after "Honey" went rogue and rampaged through New York City.

Marcie and Jason grew closer as a result of their work together, and even dated for several months. Coming off of a tumultuous relationship with Sal Walkerton, Jason particularly appreciated Marcie's quiet nature. (The fact that Marcie was better endowed didn't hurt either, apparently.)


Dumbing of Age[]

First Appearance: Dumbing of Age 22 July 2011
Hometown: Evansville, Indiana
Likes: Skating, smoking, roller derby, Malaya, Sal (as a friend)

Marcie is Sal Walkerton's closest friend, and one of the few female members of the cast who doesn't live in Read Hall. Very little is known about her, other than the fact that she's an avid skater and seems to communicate exclusively through American Sign Language (ASL).

Spoiler warning!
Plot and/or ending details follow.


Marcie and Sal first met at the age of 5 on a public playground, and eventually became lifelong friends. When Sal went to Indiana University, Marcie came along as well, and they quickly fell in with Carla and - regrettably - Malaya... though she has her reasons for that one.

A few weeks into the semester, Marcie joined Malaya's roller derby team, where she acts as an "effing wall."


  • As established in their first appearance together, both Sal and Marcie are smokers.
  • Confirmed by David Willis to be bisexual for Bi Visibility Day 2014.
  • Marcie could still speak at age 5, but lost her voice due to "stuff" at some point during her childhood. She and Sal wound up learning ASL together.
  • Is "working [her] way up to" asking out Malaya, for whom she has the hots.
