Optimus Prime memorial
- Optimus Prime memorials are statues from the Generation 1 continuity family.
Optimus Prime dies a lot. Taking that into consideration, there have been a number of memorials constructed to honor his memory. These memorials exist on a number of planets where his influence was felt the most.
Exactly what happens to these memorials when Prime inevitably returns to life is anybody's guess.

Generation 1 cartoon

In some American Earth city, television reporter Marty Minkler was interviewing Jazz and Cliffjumper at the unveiling ceremony for the Optimus Prime Memorial when Starscream and his newly recruited army of Combaticons attacked, taking the two Autobots prisoner. The statue was also damaged from Swindle's weapon fire (have the Combaticons no decency?!). Starscream's Brigade

After Optimus Prime was really dead, another memorial was constructed in his honor, this time within Autobot City on Earth. Rodimus Prime could be found moping about the statue, asking the stone representation of Prime why he kept seeing him in his dreams. The statue never responded, so far as we know.

After Optimus Prime died for the third time, yet another memorial was built in his honor. This time, it was constructed on the Autobot base planet of Athenia. Depressingly, only Rodimus Prime, Chromedome, Hardhead, Brainstorm and Highbrow attended the unveiling of the statue. Likely, with this being the third statue unveiling, the ceremonies had probably grown dull and passe'. The Headmasters issue 1
