Transformers Holy Grails and Loose Ends

[SilverDragon]

My holy grail is BW Dinobot*, since. unlike basically all the other BW dinosaur Transformers, his alt mode hasn't been reused in molds not representing the character**, and so thus there's the uniqueness factor. Also his prominence in the BW series and his nice-looking weapons.

The Animated Dinobots would also count except for the fact that they are available in shops and thus aren't rare enough to be classified as a holy grail in my eyes.

*The original mold and any re-uses of it as Dinobot, not the new Universe one.

**I refuse to count Energon Crullock because he is Godzilla and not a dromaeosaurid. Also, Rapticon doesn't count either, because he's a repaint.
