Fenris(Strucker Twins, Marvel)

Fenris is the alias of Andreas and Andrea von Strucker, twin siblings who are the offspring of HYDRA leader, Baron Wolfgang von Strucker. While the twins were in utero, they were genetically modified to have bio-energy powers they can use while in physical contact with one another; they generally achieve this by holding hands. The twins were raised under the Nazi doctrines of their father, and follow his ideals of white supremacy. When Andrea von Strucker discovers that Citizen V [John Watkins III] is actually Baron Zemo's mind in John's comatose body, Zemo kills Andrea to keep his secret. Andreas commissioned a clone of his sister be made by Arnim Zola, who replaced the original, but when Bullseye mistakes her for a Skrull, he kills the cloned Andrea.
