Bumblebee may be beloved, but so is Optimus Prime and writers have seemingly killed off Optimus a million times in different continuities. So it can’t be too much of a surprise to know that Bee has met his maker on a few occasions as well. In the “Dark Cybertron” storyline of the IDW Generation 1 continuity, Decepticon Shockwave goes mad with power and wants to destroy all Autobots and Decepticons. In the process, Shockwave kills Bumblebee and sets off a chain of events that leads to retribution against Shockwave.

Hot Rod is often portrayed as energetic, yet brash and headstrong, with an overwhelming self-confidence that borders on arrogance.[1] As Rodimus Prime, leader of the Autobots, he is significantly more mature, physically powerful and instilled with the wisdom of the previous holders of the Matrix of Leadership. In a reversal of his behavior as Hot Rod, Rodimus is plagued by lack of confidence in his role as Autobot commander and often doubts his own decisions, feeling both inferior to and in some ways living in the shadow of the previous leader of the Autobots, Optimus Prime.
While the other Autobots searched for the Matrix on Earth, Optimus Prime searched for Vector Sigma, guided through the dangers of the planet's catacombs by the spirit of Alpha Trion. Prime eventually arrived at the computer, only to find his way barred by Cyclonus and Scourge. At that moment, Hot Rod arrived with the Matrix, the same with which Alpha Trion merged, re-energizing it. The Matrix transformed Hot Rod back into Rodimus Prime and, for the first time, the two Primes fought side-by-side and defeated Galvatron.
In lieu of combining with the Prime Force, Optimus Prime can also merge with Energon Wing Saber in a similar fashion, with Wing Saber splitting into four components that connect to Prime as limbs. Wing Saber's red and white torso components can become arms for Prime while his legs attach to Prime's own, creating Prime's "Flight Mode", but the parts can also be swapped around, with Wing Saber's legs deploying large missile launchers and becoming arms to make Prime's "Fight Mode". Alternately, Prime can combine with Energon Omega Supreme to form what his packaging calls "Powerlinx Omega Supreme", but which the cartoon named "Optimus Supreme". The Prime Force drones can attach to four connectors on Optimus Supreme's body.
INFOBAR Optimus Prime (ANNIN) is a redeco of INFOBAR Optimus Prime (NISHIKIGOI), transforming into a recreation of the ANNIN edition of the INFOBAR cellphone. All-white in cellphone mode, he sports additional blue and red detailing in robot mode. Like the other figures in this line, he is not a working cellphone but can be paired via Bluetooth with a smartphone, such as an iPhone, to act as a notification alarm in either robot or INFOBAR mode. The screen is non-functional, but pre-printed cards are included which can be slid into the screen to show an Autobot logo, Decepticon logo, a mockup of a cellphone home screen, or a technical "Transformers INFOBAR" design. The figure also includes a display stand.

Late in 2008, this version of Optimus prime was one of four Classics figures repainted into HasbroToyShop.com exclusives (the other three being the Megatron from this set in G1 colors, Grimlock repainted into Overkill, and Mirage repainted into Dragstrip). Unlike those three, it's debatable just how much repainting went into Optimus, but he comes in a snazzy new box.
In robot mode he resembles previous Optimus characters: his angular chest windows are reminiscent of Cybertron Optimus Prime, while his near-animalistic limbs and color scheme are evocative of Beast Wars Optimus Primal. He has excellent articulation due to his many ball joints, and is armed with a rifle. The flame attachment can fit onto the end of the (non-firing) gun barrel.
When Ultra Magnus, Rodimus, Arcee, and Spike took cover within the Autobot Mausoleum, retreating from an attack led by Galvatron, they found Optimus having risen from the dead! Rodimus returned the Matrix of Leadership to Optimus, only for Optimus to abandon his Autobots, and flee back to Cybertron. Optimus, it seems, has returned to the world of the living changed. Once on Cybertron, Optimus orders a full-scale assault on the Quintesson base. Thankfully, Optimus managed to come to his senses when his memories of being revived by the Quintessons reemerged. After returning the Matrix to Hot Rod and ordering the Autobots to retreat, sacrificed himself once more by guiding the ship he's piloting into the Quintesson's trap. Dark Awakening
Minor note: Powermaster Prime's animation model as used in the commercials and as a character guide for the Marvel comics is a composite of the second and third designs. The body of the model is actually a straight tracing of the concept lineart for the third version (including its different rifles and twin faux shoulder stacks), with a slightly simplified drawing of the second version's head drawn on top.
A non-transforming but highly articulated Optimus Prime action figure(ine), Revoltech Convoy uses the Revoltech "revolver joints" for maximum poseability. Convoy comes with a Matrix and ion blaster accessories, as well as a few alternate hands. His sculpting is explicitly in the style of Pat "serfdom" Lee's interpretation of Optimus Prime in the Dreamwave Generation One comics, but due to physical constraints has no lack of perspective.
All of the Tiny Titans were sold blindpacked. However: there's a tiny clear window in the back to peek at the item inside, making the task of getting the ones you want easier. Every collectible card included in Tiny Titans has a scannable insignia sticker on it. Scanning the badge unlocks a random amount of Energon "currency" and a randomized bonus power-up item, and can only be scanned once per day. It's honestly quicker and less redundant to say which toys don't have this feature.

I mean you could argue that they are returning to the way the original Transformer toys worked. Here is an example of the OG Optimus toy. I went to Hasbro's website to see what the most current version of Optimus is that they are selling and I found this. That actually looks surprisingly similar, though I would argue they have gone more of the direction of making the robot look more robotic and the truck a little less truck like but its still a solid middle ground.
Part of the first wave of TakaraTomy Lost Age: Movie Advanced toys, this Japanese-exclusive redeco of 2007 Transformers Protoform Optimus Prime is given a Generation 1-styled color scheme (which is also based on his appearances in IDW's Transformers: Foundation comic-book mini-series). Protoform Optimus Prime transforms into his "entry" mode. This mode somewhat resembles a cybertronic truck, with false wheels sculpted onto the sides, and Optimus Prime's trademark windows in front. His now-blue flame decoration piece fits to the back of the "vehicle", creating the illusion of a flaming comet's tail (Not sure if this was mean to represent his jetpack blast effect or his atmospheric entry heat effect, which is for no reason: entirely blue instead of hot red). The bottom of the vehicle has small wheels to roll the toy across smooth surfaces.
