Im not saying he didnt then into an old man, I am saying he was alright when Lucci was up too.
Old man is just an effect of going G5. Itd be like you saying Lucci made Luffy go chibi mode when he ran out of G3. Its just bad cope.
Do you think the character himself is lying and you know more then him if hes about to faint or no? He is white eyed and stating hes about to faint.
Luffy didnt run out of G5 he left it.
