I have been lurking on this site for a few days reading around, and I now decided to join this site.
I am also a member of Unicron.com, there I call myself for Unicron fan. My favorite Transformer is Unicron, which I believe is no surprise due to my avatar, nick, etc.
The first Transformer series I happen to see was a few episodes of Armada. I now have seen the entire Unicron Trilogy and the 86 movie + all three movies from Michael Bay. I intend to see the rest soon.
My first Transformer was a Bumblebee key-chain a la the Bay movies.
Now I have DOTM Megatron Voyager class, ROTF The Fallen Voyager class, ROTF Ironhide Deluxe class, DOTM Sentinel Prime Scout class, Cybertron Unicron Deluxe class and Armada Unicron Supreme class as well (the latter being my favorite).
The reason for me not having seen much as well as not having that many figures yet is because that I'm a rather new TF fan. I have liked TF for over a decade, but just recently become a big fan.
