I'm working my way through reading all the old Transformers Universe profiles and saw that Jim Sorenson's blog had a few extra that weren't actually included in the comic. Are these all that exist? Is it possible that there are more Budiansky-penned extended profiles for more characters? Heck, did this practice continue after Bob was completely done with the franchise? I'm really interested in these and wish that there was a true definitive and complete collection of all the original bios.
