The Tri-verse is the world after the Ven were destroyed. The Ven's experiments were separated/mingled throughout the places they were flung to.

One section is the Milky Way galaxy, our galaxy. This is home to Earth, with heroes like Metal Man, Falcon Girl, Primary, and others reside. Across the Sun from Earth is the hidden planet Thraen, a world with civilized animals. Thraen is home to P.A.W.S. and the Animal Kids.

Another part of the Tri-verse is the galaxy of brothers Eli and Surge and their friends and enemies. Including the Smiles siblings, Destruction, and others. Probably the strangest part of the Tri-verse.

The last part of the Tri-verse is the galaxy of Argo, Nova Man, Star Girl, Robotica, and others.
