Here's a unique comparisons. This list is for Transformers that doesn't belong to HASBROS or me.
That means characters that hasn't appeared in official Transformers media or designed by me wil be on this list. Here's the rundown:

Captain America - MARVEL
Opthomas Prime - from James Farr's Trains-formers vids
Opthomas Prime (stealth) from James Farr's Trains-formers Gauge of Extinction video
-new additions-
Light Bee - http://www.furaffinity.net/user/wolfracer559/
The Captain - MARVEL
Dai Stack - unknown*

*Discovered that the official version of this character goes by the name Delta Magnus. Since this is more or less a fan character, I'm leaving him as Dai Stack.

If you want me to sprite your own Transformer, just let me know.
