Optimus Prime lives. He makes it through the entire series without dying once. This really says something, given that this is one of about 'three' continuities of dozens where he doesn't die.
The 2012 comicbook:
In The Death of Optimus Prime, all the neutrals are having a violent protest, wanting to exile the autobots who reclamed the planet. They begin beating up all the autobot guards, so Prowl sics the Decepticons on them. Ravage mauls a guy, Needlenose and Blitzwing beat a few NAILs down, and Horri-bull strangles one.
Arcee is one of the most deadly and powerful Transformers (Evidenced by her taking down the Combaticons in her first outing), and she displays it here, taking on all five Constructicons at once.
Bonecrusher gets one to delivering an Offhand Backhand to her the minute she engages them.
Issue Five has Prowl, Streetwise, and Sideswipe going to arrest the Decepticons for planning something (But also because one of them, Dirge witnessed Prowl's murder of Bombshell). When they order them to surrender, Needlenose and his flamethrower don't want to.
Sideswipe still takes him down though, but not before he bought Swindle and Dirge enough time to escape.
From issue 9:
"Us...am...were... Aerialbots. Now... Dinobots...you answer to... The Superion.
The end of issue 12, with Prowl blowing Staxx to bits and preparing to attack as the Decepticons and Wheeljack look on in awestruck terror is both awesome and horrifying at the same time. On one hand, Prowl's about kick ass which is sweet. On the other hand, Prowl's about to slaughter the Decepticons who are just revolting because of the Autobots treating them like shit and has obviously completely lost it.
The splash page at the end of issue 13 is also pretty awesome. Megatron leads a group of Decepticons, including an unwilling Starscream into Prowl's Black Room to find a "warm reception"; specifically newly upgraded Decepticons Shockwave, Soundwave, Rumble, Frenzy, Ravage, Laserbeak, Astrotrain, Blitzwing, as well as the still-living Constructicons and Bombshell...and Prowl himself, with his gun to Wheeljack's head. As Starscream can only stare in horror, Megatron proudly proclaims that Cybertron now belongs to him. Minds. Blown.
Orion out-gambitting Jhiaxus and Bludgeon in issue 19.
Soundwave and his minions taking on Blitzwing and Astrotrain in an Enemy Civil War moment. Needlenose of all people surprisingly intervenes because they've fought enough.
Later Soundwave chooses to stand up to Shockwave and fight against him, rather than join up with Shockwave's Evil Plan.
When Soundwave is staring down Shockwave and Dreadwing, they point out that he stands alone. Soundwave counters that a Decepticon is never alone, and launches his 5 current minions◊ all hidden away, onto the two.
Galvatron, still pissed about the mind bomb, vaporizes General Witwicky on the spot, and blames his death on Prowl.
