Appears in Ben 10: Road Trip

Triedge, known as Grimstone prior to being renamed in The Only Good Necroterran, is the Omnitrix's DNA sample of a Necroterran from the planet Anur Vladias in the Anur System in Earth-1010.


Triedge has a vaguely humanoid body, with rock-coloured skin. He has a large triangle-like head with two green eyes. His body is covered in small holes. His hands have three fingers, and his feet have three toes. He also has a small tail, and the Omnitrix symbol is on his stomach.

Powers and Abilities

Triedge possesses the ability to manipulate life force- moving it from being to being or using it to empower himself. This power extends between passively absorbing mana from nearby Anodites to being able to reduce incredibly powerful beings to dust. Triedge is both incredibly powerful and incredibly dangerous.


Triedge has demonstrated no weaknesses so far, save for Ben's hesitation to use him as shown in In The Shadow Of Vilgax.


Death of Ben 10

Triedge technically first appeared in Death of Ben 10 as part of the fusion Charmedge. Although Ben 10'000 knew what aliens he had fused together he refused to tell the others.

Ben 10: Road Trip

Grimstone was first used in Burning Bridges. The Blacksmith tricked Ben into absorbing Gwen's life force, distracting him for long enough to make a run for it. By In The Shadow Of Vilgax, Ben had decided that the alien is too dangerous to use.

Ben met a Necroterran named Osiris in The Only Good Necroterran. Although Ben antagonised her based on his own misunderstanding of this form, she taught Ben the true nature of their abilities and how she used them to run a hospital. Ben renamed his alien Triedge to honour this new understanding.

Ben finally used Triedge in combat in Life On Mars. He used the alien to destroy Brave New World- having deemed the creature too dangerous to live and realising there was no other way to stop it.

In Tides of War, Triedge was used alongside MindMatter, Hightide, and Powerhouse to help rescue and revitalise the T'zun Army political prisoner Marinium.

  • Grimstone was one of the five aliens to appear in Death of Ben 10 ahead of his official debut in Road Trip.
  • Grimstone's DNA cannot be stored within the Codon Stream as it poses a danger to the other DNA samples.
