@ Caricon: Most likely, the G1 Optimus. Although it's possible he might be acting like Armada Optimus. Transformers Prime/War for Cybertron Optimus are possible candidates, as well.

Even the Michael Bay Optimus is a possibility. He's pretty close to G1 Optimus's personality, with a few things different here and there.
