Rodimus taking on an entire Decepticon base, all by himself in issue 13. And almost getting away without a scratch
And Megatron's effortless take down of Rodimus is a Crowning Moment of Awesome for the villains as he sends Rodimus hurtling out of the base and into space with just one blast of his weapon.
In the International Incident Arc. Vortex proves his Badass Credentials. When the autobots show up and start fighting the combaticons, He gets shot up, and throw into a confusion through a smokescreen. Whirl pulls off a rotor (It's a sword, who knew), slashes Cliffjumper, dispells the smoke, and gets up into the air, taking on Jetfire, cutting off his wing, and sending him flying into Broadside (taking both out for the next few issues). He even pulls his boss out when they retreat.
In issue 17, Optimus Prime meets the newly reformatted Megatron and Soundwave, holding Ultra Magnus prisonner. As Megatron boasts about how invincible he has become, Optimus simply shoots Soundwave in the head, much to Megatron's fury.
And from the issue right after that where Optimus hits Megatron WITH A SATTELLITE.
And Megatron doesn't even have a scratch.
Orion Pax taking on Senate goons in issue 23. With a hearty dash of Crazy Awesome.
Sandra, a woman who betrayed Skywatch and the Autobots to the world because they had violated several laws, and had breached so many ethical clauses, gets captured. Pennington gives her the rundown, about how they are a unit, and she betrayed them. She counters that they were breaking an order from the president himself. Pennington gives her the speech that they are a unit and that the president never fought with them, Semper Fi, and all, and they should do illegal things, because they are a band of brothers. When he leaves, Ultra Magnus tells her that he agrees with what she did, she followed protocol, and stopped the people from breaking the law. It's such a swerve on genre, showing that it is not okay to run off half cocked, even if you have good intentions.
Grimlock takes the moment back from Shockwave by pre-emptively setting his ship to shoot at a nearby volcano, causing the magma to overtake the field, sealing Shockwave within the cooled magma just to make sure he couldn't escape.
