The whole Raiden thing, in two separate occasions in MGS4 was f*cking awful, and the fact they take Big Boss' arm for no f*cking reason. Just to have some trippy scene, and now they have some fake technology and seeing as it is a video game, they are just like " f*ck it, chop them up for the sake of plot " f*cking lame sh*t if you ask me.
Especially as how all these f*ckers are going to get cyborg parts over 20 years before ocelot loses his hand which he could have just gone cyborg at that point, which I think would have been way better than the whole liquid arm bullsh*t.
One other thing, I remember reading that Liquid's hair only went blonde because of exposure during the gulf war, but I cannot find this information anywhere, It is not even in the unconfirmed history. So I was wondering if they just retconned alot of that other sh*t if Eli is liquid.
I guess the age fits, he would be 12 in normal human years by the time of MGS5 so it fits in, and apparently he joined the SAS at 18 and is said he had enough combat experience by age 13, sounds about right.
Though the Gray Fox theory is pretty obviously not true, I do think he will not only make an appearance but even be part of plot twists. Some of the things mentioned could be true. Kiefer voicing two characters, the only explanation would be it is an hallucination, but it would be awesome if it was not, and there WAS a decoy of some sort, maybe not that you play as him but it does exist in some form, explaining the reasons behind big bosses insane behaviour and criminal acts.
Either way, super excited to hear more details.
