Found Beast Wars: The Gathering #2 at a random store somewhere. It was the only one I missed out of Gathering #1 - #4 and Ascending #1 - #4, so I'm pretty happy that I now have the full mini-series (if only for the sake of completion).

Also I solved my Ultimate Spider Man problem by borrowing all of the ones I missed from a friend of mine, dunno why I didn't think of that before lol

So yeah
