The user makes identical tangible and self-thinking copies of themselves. The duplicates gain all the characteristics, powers, and memories of the user. The user can re-absorb his or her duplicates when they are not needed. If a duplicate sustains too much damage, its body typically dissipates and the original is unharmed. The main downside to this ability is that for each duplicate they make, the user's power is proportionately divided. As shown in Reign Storm when Danny was battling Pariah Dark after he duplicated, each of his duplicates had 25% of his power.
- Outnumbering: The user can outnumber his or her enemies simply by making more duplicates.
- Misdirection: The user can have a duplicate distract the enemy while the user escapes. Vlad has used this technique several times.
- Duplication Absorption: The user can absorb their duplicates back into themselves, and use this in various ways, gaining some form of advantage, either by enhancing themselves, gaining the drained power, using it as a power source, etc., either temporarily or permanently. Usually, this involves absorbing the memories, skills, and experiences of the duplicate. They can also use merging as a form of healing by absorbing an uninjured copy.
- As shown in Eye for an Eye, when Danny overshadowed Vlad's duplicate it turned on him.
- It also is shown that creating a hundred duplicates weakened Vlad to the point where Danny could easily defeat him in combat. Creating that many copies of himself seem to indicate that there might not be a limit to the number of duplicates that he or possibly Danny would be able to create.
- The duplicates may share one mind or their own mind.
- Pariah Dark is shown to know which one of Vlad is a duplicate, due to Vlad's duplicate not holding the Ring of Rage.
- However it could be that Vlad intended on misdirecting him, so it possible Vlad and other duplicate users can duplicate the objects they hold or wear.
- In "Doctor's Disorders," while infected by an ectoplasmic bug, Kwan was easily and spontaneously capable of creating eight whole duplicates (to Danny's great dismay). Unlike duplicates of most users, Kwan's duplicates all shared one mind.
