THE ULTIMATE DOOM, PART ONE This episode is the first of another trilogy in this season, and it is so far one of my favourite episodes in this series and it will continue to be so if it continues to be as good as this was. I like the concept of Megatron's plan to pull Cybertron into Earth's orbit and use it to extract Earth's energy, thereby destroying Earth. I loved that cliffhanger at the end where Optimus is manipulated by Megatron into activating the third and final pylon, thus completing Megatron's plan and pulling Cybertron into Earth's orbit. It's ironic, really; Optimus fought against the Decepticons to defend humanity, whereas he, even though he was manipulated, was instrumental in its destruction. As for the Autobots' the fight with Sparkplug and the mind-controlled humans, I would have at least fought back or killed some of the slaves; after all, there's genocidal extraterrestrial robots who want to destroy your home planet, killing some of the Decepticons' distractions would have, in my opinion, been necessary. However, I can understand why the Autobots weren't too keen on fighting back; they don't want to harm any of them and they want to protect them from Megatron's Decepticons. Now, moving onto animation errors, I noticed that whatever damage Cliffjumper did to Decepticon Headquarters magically vanishes when they leave, and that the third pylon beam isn't exactly aligned with the Decepticons. As always, I love the characterisation of the Autobots and the Decepticons, and the same applies to Doctor Arkeville. I like the concept of a mad scientist who has sided himself with the Decepticons, even if they despise all of humanity; he reminds me somewhat of a human Shockwave. Both of them are Decepticon-allied scientists whom often pursue their own agendas at the cost of their leaders'. For some reason, I think that Doctor Arkeville slightly physically resembles Dr. Wily from Mega Man; it might just be me, though. I should also mention that I like the concept of humans being mind-controlled to fight the Autobots. It creates a moral dilemma: Should they kill the humans and defeat Megatron now, or should they let themselves be attacked and be distracted while Megatron pulls Cybertron into Earth's orbit? I hope that the rest of the trilogy is as good as this one.
