Near the beginning of Day 7, meme!Batman uncovers the entrance to the Batcave, as well as five velociraptors in the main wing. What does he do? He revs up the GODDAMN Batmobile, runs over two of them, and punches the other two velociraptors in the face.
Edward the Fullmetal Alchemist, instead of dying to Darth Vader, makes himself into a bomb and explodes. This was after killing several of Vader's elite guard and blocking his lightsber with his metal arm.
Bowser digging himself into Leviathan, until he reached the heart.
Ryofu punched Vader when he was ready for a swordfight.
Winslow appeared in the city by falling from the space as meteor. On Makuta's head. I dare you to say it was not awesome.
Spriggan and Max working together when the former used M67 frag grenades as projectiles while Max used his Jedi powers to hurl them at Dark Troopers in the interior of the Exactor during Day 11.
To further support his comrades, Spriggan fired a multi-barrel grenade launcher dropped Dark Trooper and used it to kill them.
"You think you Ghost in the Shell wannabees can overwhelm us?! Well think again!! You can kill us, you can dismember us, you can even pawn us! But we will not surrender until you walk over our goddamn bodies, you hear me!"
Max causes several Nobodies to back away from him.
Sam and Max using the De Soto as a method of forceful infiltration via smashing straight through the hulls of a Borg Cube, the Exactor, AND Xemnas' ship. All three instances during a singleDAY.
If this troper is allowed: Dimitri gets a minor one. After being The Chew Toy and basically being useless, he gets a bone thrown to him. With his spider-mech, he plows through Nobodies like nothing. Granted, it isn't out of the ordinary (and he explodes shortly after) but still.
Brian finishing off Enerjak with a giant rock definitely may count. Dimitri's reaction after the battle is only better.
Yes, but don't forget that Maria threw a computer at Enerjak, knocking him out in the first place.
Naked Snake barfs on the vampire-based Djinni, having eaten garlic Blutwurst.
During the fight with Zim, Sayd tries to calm him down bathing him in the blue light of Hope. This is his response:
"...I...I hope...I hope to be liked...I hope to be tall...I hope to be the best...I hope that I'm respected...I hope that I'm feared...I hope that I'm powerful...I hope to be unstoppable...I hope that all my enemies are strewn at my feet and all human beings have their legs...sawn...off..."
If Sayd could feel Zim's emotions, she would feel their natural flowing flicker and spark. A glitch in the program. A ghost in the machine. A madness in a brain pattern that must not be. But it belied something else...a base instinct and desire, for all members of the Irken Race to conquer and destroy, until there was nothing left.
Zim smiled. "Not what you expected, female? I guess you don't know me very well." He punched her.
At the end of Day 5, 63 shows up to taunt the various characters about the feelings they'd come to develop for one another, attempting to sow doubt and guilt into the group. However, Shirou points out a critical flaw int he facts of his rant, proving that 63 is not all-knowing, as well as being the first person to actually catch 63 off-guard.
Shirou, Subaru, Fate, Maria, Braig, and Shepard vs. Gilgamesh in Shirou's Mindscape on Day 7. Everyone gets a chance to show what they're made of, while the rest of the characters cheer them on.
Harima's mindscape had Pyrrhus lead an army of 2000 Greek velociraptors vs. 5000 Terra Cotta Soldiers. Harima and Karasuma fight with PENS and draw things to life in an epic battle. Harima then wins with the power of music.
Asuka's truly epic verbal beatdown on Hito-Shura, who had been being a dick for several days.
"Who the fuck do you think you are? You don't get to lecture me on anything, you fucking coward! You just run away from all your fucking problems! You ran away from me when I needed you! You ran away from having to fucking confront me later! Hell, you're just fucking running from yourself most of the time, you ball-less little shithead!"
Asuka was by this point right in front of the Demi-Fiend, screaming right into his face. "You're even worse than fucking Shinji, at least he had the balls to actually confront his problems once in a fucking while!"
The redhead shoved him to the floor with both her bound hands.
"You're pathetic. You're a coward and a fucking hypocrite." She finished coldly. "I hate you."
Everyone fighting against 63 and copies of the Black Hand, Queen, Omega and Kopassus commandos.
On Day 10, Shinji tries to drag Sakura home against her will, obviously having bad intentions. Cue Crona charging in and tackling him, before beating the crap out of him. No powers, no sword, no black blood. Just her fists. She ends up in just as bad of shape as he does by the end, but she still knocks him down several pegs.
Day 13 - Fefnir vs Sky Net. Fireballs were cut in half with whips, one liners were uttered, and a head got cut in half. From the inside.
The fight between Charade-Pool and Naked Snake during underground day. Can you say Curb-Stomp Battle?
