Zangief walking forward and hurtbox

Hi there,

I do play Guy (the orange ninja), but I have a question for the Zangief players:

If i do 2 HP, 2 HK with guy on a standing or crouching Zangief , i get a combo.
If I do the same combo on a Zangief who’s walking forward, even top close, it wiff.

Does Zangief have a different hurtbox or frame advandage when he walk forward, or is it a bug for you?

ps: thx bitbna1

It’s spelled Zangief. No “r”.
