The Utroms (a.k.a. TCRI Aliens) are an alien species in various Teenage Mutant Ninja Turtles universes. Their species name is pronounced /ˈuːtrɒm/ (OO-trom). In most continuities, they are the ones that are responsible for creating the Mutagen that mutates several individuals, most notably the Ninja Turtles and Splinter. They are also usually the species of Krang/Kraang.

  • Mortu: Mortu was the captain of the Utrom ship that crashed on Earth. After the crash, he remained the field-leader of the marooned Utroms, and worked as their liaison to the Humans. In the modern day, this makes him CEO of the front company TCRI. His name is "Utrom" backwards.
  • Council of Three: These three otherwise unnamed Utroms are the highest leaders of the Utroms on Earth. Although it is not explicitly stated, it is strongly implied that these are the same brain-navigators that Captain Mortu took orders from one thousand years ago aboard their ill-fated star ship.
  • Ch’rell: The most ruthless criminal the universe has known. Ch'rell dreams of galactic domination, and wants vengeance against the Utroms for imprisoning him and denying him his dreams by building an army and attacking their homeworld. This is the true identity of The Utrom Shredder in the 2003 TV series. Prior to his arrival on Earth, he was responsible for the deaths of millions of people in his attempts at universal domination.
  • Krang: A Utrom by the same name as the villain from the 1987 cartoon makes a brief cameo appearance in the episode Secret Origins, Part 2. He mentions how he hates walking on his tentacles.
  • Abraham Lincoln: The 16th president of the United States is seen to secretly be an Utrom in an interstitial.
  • Utrom High Council: The Utrom High Council is a collective body on the Utrom homeworld who appear to be the governing body of the planet and the navigators on the stranded ship. The judgements of Utrom criminals such as Ch'rell are carried out on the Utrom homeworld by the Utrom High Council. Not much is known, but they are responsible for the Utrom Shredder's banishment to a frozen asteroid.
  • Utrominators: The Utrominator exo-suit is what was given to the Utroms when Ch'rell enslaved them in "Same as it Never Was".
