User blog comment:Kaestal/My theory of Savitar being the Arrowverse version of Cobalt Blue (And therefore Eddie Thawne)/@comment-27673963-20170414150925/@comment-27700324-20170415145325

Savitar has white lightning man. Just because they have similar looks doesn't make them the same character. This guy is an enemy of Barry who wants him dead. Future Barry wanted to kill all of his enemies (The Rogues).
