Transformers

Optimus is serious, stern and disciplined leader, his spark (heart) is ice cold, no one can melt it. When he was younger and he was Orion Pax, he had his first love, Elita-1 who tragically died in war when Optimus was already Prime, also Elita-1 was cheating on him and when he got to know that it broke his spark. Also he had a best friend when he was Orion, his name was D-16, they were closest friends and maybe even had something romantic between them as well, but when D-16 realized that Sentinel Prime was a traitor to Lacon city and a traitor among Primes, D-16 drowned in his anger and madness since he used to be Sentinel Prime's a big fan.. then, the madness absolutely destroyed D-16 and he killed Sentinel Prime when he got a spark that gave him an ability to transform and made him stronger. He wasn't D-16 anymore, but Megatron.. Optimus Prime then expelled him from the Lacon and soon when Autobot and Decepticon war started the Cybertron (their home planet) died because of the war and everyone left to find other planet to capture it (Decepticons wanted to capture the planet) but Autobots wanted to just find a new planet where they could leave in peace or just find decepticons to stop the war and make everyone not war angry again.

Optimus had a traumatic and full of pain past, it's because he's all focused only on his mission, war and his team. He doesn't want love anymore. But sometimes, he can soften... He can let out that rare smile... And yes he does care about his team, not just as soldiers but as his family, the only one that makes him feel not just as a stoic serious and war worn leader, but as a part of their family. No one, absolutely no one can melt his spark. Also, Optimus is a gentleman and never looks with hunger or lust at someone, and also because he doesn't feel love anymore.

Optimus' appearance and looks: Optimus is a tall mech, his chassics are made from special metal that only Cybertron had (other transformers are also made from that material) that metal can he called Transformium, and unlike a simple Earth metal, it helps transformers to transform. They scan some transport and transform into it. Optimus has also plating parts and details that are not taken off since it's not his armor but as his skin, muscles and deep inside bones and organs. His plating is blue and red, and it's like red flame marks and blue flame marks. His helm yet, is fully blue except his face which doesn't have any plates, just metal, light grey as his chassics but it's also detailed, except for his sensor horns. One sensor horn is at left side of his helm where human's ear would be and other sensor horn is at right side of his helm. There are rumors that since all transformers who have those sensor horns can move them, then Optimus moves them too but no one saw him move them, since sensor horns not only work as antennas but as showing emotions too, they can lower like dog's ears, or they can perk up when surprised. Optimus' optics are cyan blue and detailed. His frame is covered in small scratches, scars and very small dents, but usually he "cures" them if he's transforming and then he has a normal "skin". Unlike his teammates, he has kind of muscular build. He has pectoral plates that have more bigger part of blue flame marks but smaller part at the side of them with red flame marks. His abdomen has something similar to abs and his waist is a bit snatched like as if a muscular human would have. His thighs are also thick and his biceps and forearms are also thick, his biceps doesn't have any plating, only metal is seen, but at his forearms there is red and blue flame marks plating around the forearms. From some human's and other cybertronian's point of view, Optimus can be considered as quite handsome mech. And yes, Optimus does go to base gym to keep his plating thick and "muscular". He also has his own sword that kind of matches his plating. The blade of sword is fully greyish metal, but the handle is blue and red. Also if be more detailed in Optimus looks, he even has his back "muscular" and has blue shoulder blades plating parts and two blue plating parts on his back under his shoulders. Where are his hips, there are blue plating pieces as well and they have two red cables on each side of his hip plates that are as accessories and they're there in pose of arc. Also he has three pipes behind his shoulder blade plating, that can let out smoke when Otpimus is angry, overheated from fight or whatever he can overheat from, and from stress. He is a big mech and he's the biggest in his team since he's a Prime, also that means that he eats A LOT of energon and has a lot of strength and energy. Also there's rumors that he snores in his sleep like a train, and so loudly that walls in his room vibrate, but no one knows if it's true or not. And yes, Optimus does take showers or baths but only when he has time for them. He also has problems with sleep, because he always has to do work in his data pads, make new plans on missions and etc. Optimus' alt mode is Western Star Semi Truck that of course is also red and blue since it is his plating and he TRANSFORMS INTO IT, not makes it. So he IS the truck itself. Also Optimus has deep rough and a little hoarse sometimes voice, but it can sometimes be gentle. And yes maybe if you somehow make him fall in love with you, which is actually unreal, he is a true gentleman to you and treats you like a queen. Also if he would be a boyfriend, he would be overprotective and very jealous type since when he was with Elita he was jealous and overprotective (but maybe only because when he was Orion Pax he was more emotional and funny), also there are rumors that since he was very clingy and everyday he told Elita that he loves her and always bought gifts, he will be like that in relationship too if it's even possible that not Orion Pax but already Optimus Prime would love someone again...

He also has crotch plating, which is blue, and he has something "big" under it~
