A/N: this was just some random little customization thing I did. It's a mix of my two favorite designs of a powered up optinus prime/convoy. 

Star convoy from Return of Convoy from the Japanese G1 Continuity.

And the super mode of Optimus from Transformers: Galaxy Force/Cybertron.

And this is the the result of the two mixed, it's not everything, but, it's still a good enough attempt.
