How nice to see you again, sliver.


Special Agent Mace, also known as a "Flec" (short for Reflection Police), is an enforcer in the mirror world who keeps the barrier between the prime world and the mirror world intact. He serves as one of the two main antagonists of Book Two.


It was stated that he used to be a reflection of a prime until they died and he became a mirror officer.

Book One - The Perennial Child

The Chrome Car

After a reflection starts acting on her own, he and Sieve are tasked with sanding the escaped reflection down to dust. They apprehend the reflection’s prime self, Tulip Olsen, but Tulip escapes and the two give chase. He sends Sieve into the prime world as he goes after the reflection. He goes to end the reflection but only manages to cut of a foot of her hair as she goes into the prime world and escapes.

Book Two - Cracked Reflection

The Black Market Car

After months of tracking down the reflection, now going by M.T., they find her in the Black Market Car and give chase. After several close calls she escapes and hides behind a deer in the Family Tree Car. They give up for the time being due to Sieve’s suits being compromised.

The Map Car

After the Map Car’s landscape becomes real, he and Sieve find M.T., along with Jesse Cosay and Alan Dracula, and go to sand her.

The Toad Car

As the pair try to apprehend M.T., the trio gets away and lock themselves in the Toad Car. He goes to get heavy machinery to open the door when they can’t open it themselves. He returns a few hours later with a machine to open the door. However the door opens as he is filling it down Jesse takes the Toad, which they need to kick to get out, with them so that they trapped. When they are sealed inside Sieve comforts him.

The Mall Car

After Jesse goes against The Apex, Grace takes out a mirror to summon him and Sieve to the Mall Car. After M.T. collapses after Jesse couldn’t leave with her, they get ready to sand her.

The Wasteland

He and Sieve chase M.T. and Alan Dracula until he catches her. However a car is coming at them and they jump off into the Wasteland. While M.T. is alright, Mace’s lower half is severed by a wheel. Alan Dracula meets up with them and she places him on the deer and go away from the train. As they walk he mocks her for wanting a life different from her prime and she calls him a coward for not being recycled when his prime died.

After awhile they train starts to pull them back to it. When they are attacked by Ghoms, Alan Dracula shields them in a ball of his antlers and he asked M.T. if she can even get off the train, how would the world react to her and how would she live a normal life along with Tulip. He then tells her she was created to help passengers grow and that it is her only purpose. She refuses this and runs away. After Alan Dracula lowers his antler shield, she propels them back to the train and uses a Harpoon Pack to grip a solid surface. When Mace tries to take them both out, she grinds him to his death on one of the train's wheels.


He is a ruthless mirror policeman that will go to any means possible to prevent rogue reflections, or "slivers," from escaping into the prime world.

Mace has been shown to be a bit more serious and aggressive than his partner Sieve. He is also a bit arrogant and snarky as shown with his interaction with Lake.


  • Metallic Bodies - Like all Mirror People, Mace is nearly indestructible. He could survive falls that would be fatal for an average human. However, they are susceptible to damage from train wheels as shown in his death.
  • Equipment
    • Skins - Agents have special suits that cover their bodies (particularly their face and hands), which allow them to leave and enter the mirror world at their leisure, to the point that they can "teleport" between reflective surfaces. However, the suits are susceptible to tearing.
    • Sanders - Agents wield long sanders that are wielded similarly to tonfas, which are presumably used to grind Slivers into oblivion.
    • The Lawbreaker - A battery charged high tech laser with the ability to evenly cut through car doors.


  • His car made a cameo in the short "The Snow Car."
  • Mace and Sieve were created at the request of Cartoon Network: the original script for "The Chrome Car" by Lindsay Katai featured nameless comic relief cops. The executives came back with the note that the episode needed higher stakes and more action, which led to the creation of the two characters.[1]
  • Lindsay considers Mace to be Javert from Les Misérables, both the original novel and its musical adaptation.[2]
