Ability duplication is the ability to copy multiple abilities through physical contact.
- Dexter Lee has this ability naturally.
- Leo Castern also possesses this ability naturally.
Dexter can replicate any singular ability from a touch. He can also replicate abilities from others with multiple abilities, but then he cannot copy their original ability. The touch doesn't have to contact skin to work, and the ability sometimes shows as a white glowing light. He also experiences a tingling sensation when he duplicates. He couldn't control the ability at first, since he accidentally and unknowingly duplicated ability sensing, but he has since learned to block it.
Leo can also replicate any ability using touch. It is unknown exactly how he does this, or how it is shown or how he experiences it. He can usually control whether or not he duplicates, except if he is too weakened to block it or sense it happening. He originally mimicked his sister's ability out of jealousy. All other abilities he gained were taken deliberately, except for the abilities of two individuals which he duplicated when nearly unconscious. At first, he would usually duplicate every ability a person possessed which had been manifested at the time. However, after he lost control of his abilities and nearly died, his core ability became faulty and now he can't always duplicate every ability a person has. He normally only duplicates one.
