In robot mode, Voyager class Optimus Prime is proportionally more accurate to his CGI design than the leader class toy and has a more accurate headsculpt, but due to the aforementioned lessened complexity significant sacrifices had to be made, such as "cheats" to the transformation sequence, to achieve this and thus he is overall less accurate than he initially appears. In addition to previously mentioned changes, he carries much of the truck's front hood, grill and fenders on his back like a backpack. However, he maintains a superb level of articulation and posability.

In the Cybertron universe, Cybertron was under attack by two of the Heralds of Unicron, Nemesis Prime and Ramjet. They had already damaged Alpha Trion, and while Ramjet engaged Vector Prime in a duel high above Cybertron, Nemesis Prime got past Sentinel Maximus and revealed his plan to use the Dead Matrix to drain Primus and use the energy to revive Unicron. Omega Prime, a combination of Optimus Prime and his brother, Ultra Magnus, appeared to challenge Nemesis Prime. The brothers recovered, only to receive Optimus Prime, bearing word of Vector Prime's death in battle. Prime and Magnus were subsequently seen planning the hunt for Unicron with Sentinel Maximus.[40]

After weeks of Decepticon silence, Optimus Prime decided to get proactive and sent out patrols all over the planet to try and flush the villains out. None of the patrols reported back with any success, however, and Prime realized that there was one area of the planet that his troops had deliberately ignored: the mysterious "Nebulos Triangle". Quickswitch, Scoop and Quickmix were sent into the Triangle, and they did indeed discover and foil the Decepticon plot going on in the area. Decepticons Underground

Armada Built to Rule Optimus Prime transforms into a fair approximation of his vehicle mode, but the robot mode is quite inaccurate, due to the very broad, flat Trans-Skeleton with thin, stick-like limbs attached to it. The set came with a very simplistic "Mini-Con" Sparkplug partner kit that did have a more dedicated "Powerlinx" connector than the standard construction pegs, though these are a bit too thin to be used as attachment points for regular Mini-Cons (they stay, sort of, but it's a very loose connection). The 101-piece set also features pressure-launch missile-firing "smokestack" cannons.
Early in this new series of encounters with Megatron, Red Alert contacted the Autobots on Earth and asked for Optimus Prime to join then on Velocitron. Ransack and Crumplezone tricked Hot Shot and Dirt Boss into believing that a race between them would determine which of them would be allowed to race Override for the Planet Cup. During the race, Ransack and Crumplezone caused a rockslide that buried Hot Shot. Hot Shot was saved when Optimus Prime, Vector Prime, and Landmine arrived, but Optimus was upset that Hot Shot had become involved with the locals. Clocker and Brakedown were eager to help the Autobots. After being unable to obtain the Planet Cup from Override herself, Optimus Prime endorsed Hot Shot's plan to win the cup in a race with the aide of the other Autobots. Ransack and Crumplezone were contacted by Megatron and were told to keep on eye on things. They also decided to enter the race, either to win the cup and cause as much damage as they could to the other racers. Override, Dirt Boss, Ransack, Crumplezone, Optimus Prime, Hot Shot, Red Alert, Landmine, Clocker and Brakedown participated in the qualification round. In the final episode of Transformers: Cybertron, Optimus Prime proposed a new Space Bridge project using the power of the four Cyber Planet Keys and the four great Cybertronian ships. Many Autobots and former Decepticons joined in the project. Jetfire was left in charge of Cybertron as Optimus Prime led the Atlantis with the Earth Cyber Planet Key, joined by Red Alert, Safeguard, Scattorshot, Leobreaker, Menasor, and Heavy Load.

Rodimus can be unlocked by beating "Dam 6" in Arena Mode, credited as Hot Shot. Rodimus is described as being young, impetuous, showing enthusiasm and confidence which borders on arrogance. He boldly claims that he has both skill and looks, though he is not too keen being paired with Kup on missions. Somehow, he became corrupted by Dark Energon. If the player manages to defeat him, he calms down, shrugging off the effects of the Dark Energon and returning to his regular self.
Apart from this, Optimus Prime is also the weakest link of the gestalt combination, due to a number of design failures attributed to his torso mode. The square holes-and-tabs used to secure the arms together when in torso mode are too weak to remain locked in place (though a very small amount of copies can secure the arm well), and are prone to falling out of position should an attached arm be moved. The torso mode's skirt plate is also attached to the stomach rather than the pelvis, rendering the waist swivel nearly worthless due to the skirt obstructing articulation.
Hot Rod has a youthful attitude, and serves as an older brother figure to Daniel Witwicky, son of Autobot ally Spike Witwicky. He has a sort of mentor-student relationship with the veteran Autobot Kup. He was also good friends with Springer and Arcee. Later in life, he temporarily bears the Autobot Matrix of Leadership and becomes Rodimus Prime (Rodimus Convoy in Japan), and new leader of the Autobots.
Optimus appeared in the 2008 BotCon voice actor play "Bee in the City", voiced by David Kaye. In this story, Professor Sumdac attempts to create a teleportation system to get the Autobots to Cybertron, but an interaction with Sari's key ends up transporting Optimus Prime, Bumblebee, and Sari to Transtech Cybertron. There, they met Flareup and are detained by Shockwave. Bumblebee teams up with Beast Wars Megatron to free his comrades, but must then stop Megatron from taking the key for himself. Afterward, the Autobots and Sari returned to their own dimension.
1· To calculate the average price per piece in a year, I took the price per piece of each set made that year, multiplied it by the number of pieces in the set and then averaged all the weighted prices. I used a weighted average because when we are looking at the price per piece we are essentially saying we could buy x number of pieces for y dollars. Larger sets tend to have a lower price per piece so in effect you could get more pieces at that lower price that year. Note: this was done using US retail price data from Brickset.
The Power Plus series are similar to the Power series, except these come with the core that unlocks extra features. The Bumblebee figures in this series are nearly the same as the Power series versions (Camaro ‘Bee’s Power Plus figure has his unmasked head), so if you’re going to get them, and you want the cores, go with these versions. If you want Optimus Prime at this size, though, you’ll have to go with this version.
When Optimus transforms, his cab becomes an ion blaster and his trailer disconnects, forming a combat deck. The combat deck supports a mobile battle-station and command headquarters armed with assorted artillery and beam weapons that fire automatically. The combat deck can also serve as a radio antenna for battlefield communications between the autobots. The combat deck also included "Roller", a mobile scout buggy meant to scout behind enemy lines. When Roller is deployed, Optimus can see and hear what Roller sees and hears.[4] Injury to one component is felt by each of the others. If the combat deck or Roller were to be destroyed, Prime could survive. However, despite the slight degree of autonomy they possess, the combat deck and Roller would not be able to survive without Optimus.
Part of the first wave of battle upgrade Hero Mashers toys, Optimus is a non-transforming robot who can swap any of his parts out with other Hero Mashers figure to create many combinations. He includes his iconic Energon axe, a large projectile-launching gun, another large gun, two missile packs, and an arm for Ultra Magnus. Optimus Prime also has a pointing right hand, which allows you to do a certain Optimus Prime pose in a Dreamwave Productions comic.
When Sideswipe was accused and convicted of destroying the Nova Suspension Bridge, Optimus was infuriated that one of his own Autobots could commit such a heinous act. Optimus was tasked to hunt down and deactivate Sideswipe, though the task proved to be easy as Sideswipe did not run, hide or resist. After Optimus had deactivated Sideswipe, he was approached by Prowl, who pointed out that Sideswipe's actions made little sense, as he had committed the crime in broad daylight before many witnesses. Agreeing that the Decepticons might be behind the situation, Optimus allowed Prowl to take a team of Autobots to Carob Island to clear Sideswipe's name while Optimus and Jazz stayed behind to continue working on human/Autobot relations. Prowl returned with evidence that it was indeed a Decepticon-controlled clone of Sideswipe that had committed the crime. Optimus then presumably reactivated Sideswipe when his name was cleared.
