Originally named "Blitzwing", the toy that became Obsidian looks very little like the character who appeared in the Beast Machines TV show. This is often the kiss of death for a toy when it comes to me (particularly characters like Obsidian who I loved). However this toy is still great. Obsidian is very pose-able, and has a very emotive robot and vehicle mode (thanks in large part to his giant neck, which makes it possible to do very cartoony poses). Furthermore, his colour scheme is oddly nice - blue and green don't do it for me usually, but this toy is quite cool as it is. (The RID repaint was much nicer though).
