Hi - currently GIMP animations are GIF only - (or maybe MNG). In the
former case, just one level of transparency is suported, and that is
total transparency. In the later you can get away with with various
levels of transparency, but I am not sure you would get the final
result you want.
The solution for your case is compositing the final frames before
saving then to an animation.
Thus, for each translucent layer, you have to create a new layer,
either with your background or with the frame you want to "show
through", and combine these two layers into a single one, with
opacity 100.0 (and displaying the final effect you want to see).

MNG? I'm not familiar with that format... What is it? It supports animation?
If you are designing for the /Web/, as your need for opacity may indicate,
I suppose you ought to give up the fade-in (opacity) effect. MNG is not
supported by Web browsers as far as I know, especially not if embedded in
pages.
Alternatively, you could lay the object (text?) over solid colour back-
ground, in which case there is no need for transparency. If you design an
animation that will form part of a desktop application, there is probably
not much you can do.
