What else can be added to the Final Fantasy VII Compilation?

[Sephiroth]

No it hasn't because none of what you just said makes any sense. There is no such thing as "just an id" as the very definition of Id is that it is part of a whole.

Now, if they have said Jenova is a being of baser instincts and desires with no higher function, present the evidence.

Yes, it has. When the Ultimania says in its JENOVA chapter, that JENOVA is only acting instinctively, then it does. Square Enix offically published material is by far woth more than your word and it absolutely makes sense as while we have three parts, including the Id, me calling JENOVA an "Id" will immediately tell everyone who knows the word, that it is just (a genderless, emotionless and) instinct-driven being with the purpose to travel around, split, absorb/infect and reunite, repeating that process over and over again like an animal. For that it uses its abilities to act like a chameleon and finally fulfill what it is "programmed" for. It is said it is instinctive, so it is instinctive. I am no longer in the mood to argue with people as you, not accepting that there is way more published material than you want to use or like. You cannot make any claims and not accept things if there is just more. And your Lightning post the last time already was evidence enough that you are not even interested in such things. Read it ot don't read it but don't complain over things if you are missing any information. I'm done with you since I have no intention of another "PuPu"-like discussion.

EDIT: And don't waste your time. You are on my IL now. However, I have sent you a PM so you can still see the part of the Ultimania. For the rest, the textboxes of the game say everythings.

... it only follows its instincts to
incite ruin, utilizing its mimic ability (-->P.211) to infect other living
organisms with its virus. In addition, due to its abnormal resilence, even if
dismembered, its cells will call out to one another, seeking to reunite into
their original form (-->Reunion/P.211) ...

Please read everything next time. It is intelligent like all animals but what it does is instinctively. It does not act like it acts because it is a person as it is not. JENOVA is instinct-driven (by far more than we as "animals" are as it only works like that). That is why "Id" is absolutely fitting, being the instinct or following only the instinct is of no relevance (as we both are partly the instinct and also follow it) when it comes to that. It can be understood what I mean.

It is always bad when explaining things gets like this. So sorry but let's just avoid each other.

Now back to topic.
