Albermech and Chaos were the creators of the Black Light.
Time Travel - Paradox shattered the minion of Black Light by going back in time to present again.
Mana - Grandma Verdona can protect black light with energy fields (because Mana is energy and Black Light is for DNA)
- Gwen (Gwen is unprotected for her low skills of Mana)
Omnitrix - The Omnitrix is a barrier, because Omnitrix has power to regenerate Ben (in Vengeance of Vilgax) and DNAs of Omnitrix can regenerate its user's DNA. In Darkest Night, Ben was a zombie but Omnitrix freed him from Black Lights control and by attaching Ben's leg with of Lodestar's.
Sycorax - Sycorax is able to withstand Black Lights abilities by their skills and tactics of Mana.
