How much old is Optimus Prime?

Excuse me, could you possibly clarify the question regarding Optimus Prime's age? It's worth noting that Optimus Prime is a fictional character from the Transformers franchise, a series of toy lines, animated television shows, and films. As such, he doesn't have a tangible age in the traditional sense. Instead, his existence and storylines are based on the creative narratives developed by the franchise's creators and writers. However, if we're discussing the timeline within the Transformers universe, it's often subject to change and retcons depending on the continuity or media portrayal. Some iterations may provide more specific details on Optimus Prime's origins and lifespan, while others may remain vague. So, to answer your question in the context of fiction, it would depend on which version of the Transformers universe you're referring to. Would you like to know about a specific iteration or are you seeking a general understanding of how age might be conceptualized for this character?
