|First appearance||Seeing Is Believing|
- User: Ulrich Stern
- Exchange: N/A
- Description: Two yellow ghosts flash away form his body, turning into clones.
Triplicate is Ulrich Stern's unique ability on Lyoko. He has the power to replicate up to two clones of himself. Each clone only has 1 Life Point. Ulrich and his clones can run around an enemy in a triangle formation with one Ulrich at each corner and can triple team the enemy. Ulrich calls this move Triangulate.
While the clones are very easy for enemies to pick off, they can kill monsters. Their swords can also be used by Ulrich and even other Avatars. Also, while Ulrich's clones are just as capable as he is in combat, they seem to vary in intelligence. Sometimes not even able to speak, they are merely puppets to Ulrich and do whatever he tells them to do. Other times, they are very intelligent, being able to speak, think, and even act like Ulrich, taunting X.A.N.A.'s monsters and or kicking them into the air for fun. For example, a Kankrelat in Tip-Top Shape.
In the fourth season, he used this cloning ability only once; against X.A.N.A.-possessed William in Double Take. Unfortunately, William used Super Smoke and devirtualized the real Ulrich before he and his two clones could even attack.
Season Five: Evolution
Ulrich uses triplicate once to defeat The Ninja in Intrusion. A clone is devirtualized while the real Ulrich is devirtualized too.
The process is reversed by the ability of "Fusion."

Season Five (Code Lyoko: Evolution)
- It is unknown when Ulrich discovered this ability since it was not used in XANA Awakens.
- In Quest for Infinity, Triplicate is the only way to get the lava from head of a Volcanoid away in order to be able to damage it.
- In Evolution, if one clone is devirtualized the second clone disappears as well.
- William is the only one to devirtualize the real Ulrich when Ulrich used Triplicate.
- It is shown that if you destroy the original Ulrich the other two clones disappear.
