Optimus Prime at his best was always a joke cracking dad and we don't give that enough appreciation like we should.
It's when he's allowed to show his jovial side he can feel like more of a character than just a walking series of stoic speeches.
Peter Cullin's family says Peter passed away peacefully, and they left a message following his death:
“His family asks that you honor his remarkable legacy by serving your communities and leading others with compassion, integrity, and loyalty and always remember, ‘be strong enough to be gentle.’”
“Above all, do not lament my absence. For in my Spark, I know that this is not the end. But merely a new beginning. Simply put, another Transformation.” ~ Optimus Prime
Thank you Peter Cullen. RIP
