Okay, two possible back stories behind this picture. Take your pick of which one you like best...
Backstory 1: After the battle of Autobot City, the mortally wounded Optimus Prime was taken to the repair bay. Swoop, though devastated by the loss of both his creator Wheeljack and his mentor Ratchet, did his best to help Perceptor save the Prime, but in the end their efforts were in vain.
Prime, knowing his death was imminent, removed the Matrix from his chest and tried to give it to Ultra Magnus, but his strength failed him and he dropped it. Swoop, being close by and wanting to help the fallen Prime in some way, quickly bent to catch the artifact... and was immediately transformed by its power into Pterodactus Prime, the new leader of the Autobots.
Bearing the Matrix of Leadership in his chest and his new alt mode of the Quetzalcoatlus (a larger cousin to the Pteranodon of his former alt mode), he must now work to unite the Autobots against the dual threats of Galvatron and Unicron... but first he must overcome the prejudice against the Dinobots, the sudden distrust of his brothers, and his own youth and inexperience.
Or Backstory 2: I got this weird idea after someone at Fandemonium saw me in my Swoop costume and somehow thought I was Optimus Prime.
Anyhow... Swoop as a Prime. I don't know what Swoop's sword really looks like, so just had fun desigining one of my own. Maybe the Matrix reformatted his weapon along with his body.
Huh... maybe I need to make his chest broader. He needs to be able to fit a Matrix in there, after all...
I know I owe people art requests, but sometimes I just need to take a break and do some artwork just for me. This was fun, and working on it gave me the break I needed. Will tackle more requests soon...
