Algernon, or Robo-Rat McEvilFace (as called by Blaze and Torq) is the main antagonist of Chapter Two of Season One in Mech Mice Tactics. He is a rat who works with the Dark Union. He first appears after you defeat Queen Termina in The Storm of Chapter One of Season One. He reappears in Chapter Two, in Algernon's Laboratory talking to Termina. He sends FrankenBug after Dusty for an experiment in this level.
- There is a book called Flowers for Algernon which is about Algernon, a laboratory mouse who has undergone surgery to increase his intelligence by artificial means. The story is told by a series of progress reports written by Charlie Gordon, the first human test subject for the surgery, and it touches upon many different ethical and moral themes such as the treatment of the mentally disabled. The Algernon in Mech Mice is very similar to the one in the story.
- Algernon is a given name which derives from the Norman-French soubriquet Aux Gernons, meaning "with moustaches".
- He has a metal arm.
- He presumably likes to eat Grub Yums, as seen on his workdesk in Algernon's Laboratory.
