My first custom. Not much really.

I made the staff out of a Doctor Who clockwork robot knife and a random piece of Lego.

Optimus' backpack is a broken Energon Prowl.

Bio:

17 years into the future, Optimus rests on Cybertron, the war won. But when Megatron returns, Optimus, with the parts of an old comrade, a Cybertronian dagger and a damaged energon hook, flies down to Earth once more, to stop Megatron once and for all.

EDIT: Don't comment on this anymore! Comment on this:

op prime with a backpack? lol that actually looks kinda cool

 

Gee, thanks! Glad to see you like it. I've seen your customs and they're awesome.

 

Looks like an elderly prime, nice though

 

Come to think of it, it actually does look like an Elderly Prime! Maybe I'll reference that when I do his bio.

 

I have to admit, at first I couldn't get Optimus' backpack on. But I eventually got it on.
