Fusion Moves are special moves that combine two Super Moves. They are seen in the anime, DS game, and TCG, but do not appear in the arcade game.
In the anime, several cases of Fusion Moves are seen. The first was Thunder Storm Bazooka, combining Thunder Bazooka and Cyclone to defeat Saurophaganax and later Torvosaurus. One was used against the Black Tyrannosaurus, when 14 dinosaurs merged their attacks in order to break though Fire Scorcher and hit it in Dinosaur War!. Dr. Z had Terry and Spiny combine Volcano Burst and Shockwave to blast a target Ursula, Zander, and Ed were holding in Desperately Seeking Spartacus (it is never used again). Another was in order to break into the Dark Pterosaur in Fate of the Cosmos.
When Ace twice uses Cyclone to suck up water and turn his attack into a "Hurricane", it is similar to what a Fusion Move from the DS Game would be (see below) (although this was not used by merging two moves, just Cyclone and water frrom sea and the river). And when Chomp and Torosaurus combine their Lightning Strike Move Cards to defeat Terry in Rhino or Dino?, it is basically a Fusion Move where both Moves come from the same element.
At various points, such moves are called either "fusion moves" or "combo moves". While there seems to be little correlation between title and effect, "fusion moves" typically involve the effects of two or more Moves combining, or their energies forming a single blast, while "combo moves" tend to involve two or more clearly separate attacks simply hitting the same opponent at the same time.
The DS Game also has fusion moves, but its more like adding a second attribute to another Move Card.

In the TCG, Fusion Moves are also seen, and are similar in idea to those from the DS Game, adding an element to a pre-existing Super Move. In fact, the card artworks are Arcade Move Cards with the addition of graphics representing a second element, or in some cases, a recognizable second Move Card. The lores require more than usual to use, however, the power boosts they give are usually more than regular Super Moves (some even more than Ultimate Super Moves!).
