[@Ruby] He doesn't drain anything, he simply nulls it. He is like the counter to Eve and the powers that derive from her genes.
Though I can say that he can nullify only a limited amount of her powers if you'd like.
Edit: Rather than limit the amount he can nullify, maybe #1 has such an understanding of each individual's powers and especially from where her powers come from that she uses her own powers to block out Nile's effect on her.

[@MonkeyBusiness] Well it's not more about power than it is from where they derive the power. From Eve's genes. He just turns the power off.

Could be Alpha's so close to EVE that trying to nullify her is like trying to nullify solar energy if you're standing on Mercury.
