A LONG TIME.
Assumed male
At first impression, Optimus Prime can seem stern and serious to most. He has that effect on people. But if you scratch the surface of the old Autobot, you'll find a kind and caring leader who just wants to look out for his people (as well as humans). The only reason why he's so distant is because eons and eons of war have caused him to become that. He also hides an inner pain of losing his most trusted comrade, and blames himself for this. He is quite a humble Cybertronian, despite his large build, and respects the rights of any being that is sentient. His true virtue is his bravery, as he has been called "the bravest of the Primes". He cannot stand to see casualties unless it is the last option available, even to the Decepticon lower-class.
The high council was astounded by this bot's selflessness and gentle personality. Never before had a Cybertronian so just present himself in such a way. It had been eons since the age of the Primes, and here stood one capable of becoming one. They sent Orion Pax into the center of Cybertron, where he met Primus, the original Autobot. Primus saw the good in Orion Pax and presented him with the Matrix of Leadership, transforming him into Optimus Prime.

The rest is spoilers for the show so click here if you want spoilers!
Basically, the Autobots fight the Decepticons, ranging from taking down a warrior named Skyquake to fighting Unicron himself. Megatron's death at the site of the space bridge put Starscream in charge, and for awhile, everything was manageable. Until of course, Megatron came out of his comatose state and took his rightful place back as the leader of the Decepticons once more. With Megatron in charge, things became distinctly more complex for Team Prime, especially when they learned that Unicron was actually the Earth (yes, you heard right.) But along with this, came an unlikely truce. Megatron wanted Unicron taken care of just as much as Optimus, and thus, joined forces in going to destroy him.
However, this was at the cost of Optimus's memories. Not one to miss an opportunity, Megatron brainwashed Optimus into thinking he was a Decepticon, and that Ratchet was the 'Doctor of Doom' that destroyed Cybertron. We all know how true this is, and it didn't take long for Optimus to start getting suspicious of Megatron's actions. Team Prime attempted to restore Optimus's memories, managing at the last moment, the Prime himself couldn't remember what he did during his time as Orion Pax.
Season 2 then became a race for the Iacon relics, ranging from the Spark extractor to the forge of Solus Prime to the Phase Shifter. However, there was some danger in this. They almost lost Bulkhead among the scuffle, and the repercussions of the event were to last. But that didn't stop them. Bulkhead recovered, and Team Prime soon regained it's strength. And a new recruit, Smokescreen to boot. One of the relics was a large sword called the Star Sabre, and could only be wielded by a Prime. In Optimus's hands, its a formidable weapon, capable of slicing entire mountains.
Lawful Good
Allowing a human casualty because of the war his kind had started.
~Optimus is a reactionist. He will not actively seek out violence unless he is attacked first, and it will only be for self defense. However, if a human casualty occurs, or too much violence is taking place, he will become the instigator and take it upon himself to put things right. (i.e. kick some ass)
~He's never partied or had any fun since he became a Prime. His sense of humor is null and void, so any jokes you might possibly throw at him would be received with an eyebrow raise or a confused face.
~Optimus has a LOT of weaponry at his disposal. First of all is his alt mode, which he turns into a semi truck (his trailer will come with him, but most of the time he'll be without it). He can do a ton of damage in this mode, ramming into anything opposing him. He's also equipped with two guns on his hands, which can also turn into two blades. In the movieverse he also has brass knuckles equipped onto his hands, so I'll be including those as well.
