LEGO is not a cheap toy and has never been. The brand has stood for nothing but the highest quality and hopefully any issues it has had with changes in manufacturing are only the result of temporary growing pains. Next time you are out buying a LEGO set for a loved one or for yourself, take a second to thank everyone who ever bought one for you as a gift.
A redeco of the sword-wielding version of Battle Masters Optimus Prime, Silver Knight Optimus Prime is a non-transforming "Rock 'Em Sock 'Em Robots"-like toy with arms that punch through the use of levers in his legs. He can also be placed on the included controller handle, allowing the punches to be activated with a pair of triggers. Optimus Prime was only available in a Target-exclusive two-pack with Grimlock.
Voyager Optimus Prime is a redeco of the toy from the first movie's toyline. Like several redecos or retools of 2007 movie toys, there has been some effort to make this release noticeably different from the previous releases, though the toy ends up looking less accurate to the actual movie appearance than those previous releases. Optimus Prime has a sort of faded Autobot logo on the side of the truck's bunk, and kanji (Chinese characters) on the roof (ending up on his knee in robot mode.) The word "上海将军" means "Shanghai General", while "大将" means "Grand general".
Q-Transformers Optimus Prime is a tiny super deformed toy based on the Alternity Convoy design, transforming into a Nissan GT-R R35, though his legs retain the traditional blue truck bed motif. The English name on the packaging refers to him as just "Optimus". He comes with a code for unlocking "GTR Optimus Prime" as a playable character in the Q-Transformers: Mystery of Convoy Returns game. Standing at only slightly less than one inch and a half, this is actually the smallest transforming Optimus Prime ever made, which is a fairly impressive feat considering the surprising amount of detail in sculpt and paint apps.
Reissued in 2003 as part of Takara's Transformers Collection line of reissues. This version (#13 in the Collection series) was retooled from the 2000/2002 Rodimus Major tooling in order to make the fists and engine block hole wide enough to equip Firebolt. In addition, the original 2 guns had their posts modified so that a Targetmaster Hot Rod could still use them, if the owner chose to.
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.
