Below is a link to a link to my musing.  (Special thanks to Reprolabels for the gold foil Micromaster Devastator stickers).

I know you got the Grimlock name from RiD, but doesn't that conflict with the T-rex guy?

Well, this particular Grimlock comes from the RID Universe....  The Bio sort of fits in with the Universe Devastator bio that I wrote plotwise.  Hightower ended up in the future, and shrank in transport from his dimensional universe.  The remaining 3 ended up in G1 Cybertron's past.  In escense, the Build team traveled in from the RID universe to the G1 with some unanticipated complications.

good bio I like it

Thanks!  Also, for anyone curious about the previous Bios that I mentioned.....

See:

Micromaster Devastator

Hightower

that was pretty cool, i dug it!

Hmmm....interesting bio. Lots of detail. I like it. 

I dont like the fact that the constructicons were autobots b4...but there are so many plotholes in g1 i doesnt matter, they are original decepticons to me.
