Tatsumi, on his first mission, holds his own against an experienced Teigu user armed only with an ordinary sword.
Tatsumi and Bulat vs The Three Beasts; the fight starts off with an immediate CMOA when Bulat unleashes Incursio and kills Daidara by splitting him vertically in half before the hulking axe-wielder can even strike a single blow. (Bonus points for Daidara realizing he's screwed a second before the blow lands and the look of terror on the axe-crazy serial killer.) Then Bulat manages to fight General River equally in an epic Teigu battle filled with dragons made of water and lightning fast armour attacks, and pulls a Taking You with Me as he gives his life to end River. Then Tatsumi inherits Incursio and after verbally smaching Nyau down, enraging the sadist until he loses it and attacks head-on, and then kills him with a single punch, sending Nyau flying into a wall with so much force that it kills him on impact.
In the middle of Dr. Stylish's attack on the Night Raid base, he's starting to take the upper hand with his poison when Najenda and two new members pull a Big Damn Heroes, swooping in on a flying manta ray. Susanoo, who is a Teigu and thus cannot be affected by the poison, makes short work of Stylish's pawns and, with Mine, holds off Stylish's One-Winged Angel mode long enough for Akame to land a killing blow.
Lubbock, normally the Butt Monkey, defeats two of the four Rakshasa Demons on his own; even Akame had a bit of trouble against the one she faced off against.
How he kills them both deserves explanation. First he gives up playing being dead so that he can save the life of a female spy allied to Night Raid, then fights against the first of the Demons long enough to get his threds inside the monk's body and slice his heart to pieces. Then after the second Demon manages to negate his advantage he throws a knife at her in what looks like a desperate last attack, only to pull the strings attached to the knife back and send it flying into the Demon's back as she prepares to execute him.
Mine's fight against Seryu, the second time around. She has not only Schere to avenge but also Chelsea, whose body was eaten by Koro, much to Seryu's glee. Even though most of her scenes with Chelsea were about Chelsea annoying her, Mine still remembers some fond times together, which she thinks about when cutting Seryu in half.
Wave finally snaps and falcon punches Syura following a day of seeing the horrors of Wild Hunt against innocent people, topping off with him threatening Kurome, as he's struggling against the anger.
Chapter 47 Wave getting up after Shura stops holding back and lands a powerful blow to deliver a No-Holds-Barred Beatdown. If not for General Budou stopping him, Wave would have stomped Shura's crotch till his foot finally met the ground, but a brief small consolation afterward is that Shura, for the first time since his debut, is bitter.
Champ finally dies by being burned alive by his own powers until nothing but his charred black skeleton remains. It can be argued that he could never suffer enough for all the crap he pulled, but at least the readers won't have to suffer his presence again.
That issue was just brutal to Wild Hunt; after Champ's long-earned death Cosmina is sniped through the throat by Mine as she attempts to rape Run and Enshin is slashed by Akame after a beautiful display of agility where she proves that despite his Teigu being at full-power, killing him doesn't even take effort on her part. He can only remark on Akame's strength as he drops dead.
Chapter 51: Tatsumi admitting that he has a girlfriend to Esdeath's face. To be fair, she didn't let it bother her much after a while.
Chapter 52: Lubbock revealing the Trump Card of his Teigu and garroting Syura with it. And this is after under-going Cold-Blooded Torture where he lost a testicle. His murder ot Syura, and avenging all his victims, is one of the most satisfying moments in the entire manga.
Chapter 56: Tatsumi becomes the first person to ever land a blow on Esdeath in the entire series. It was strong enough to KO her for the rest of the fight and even after the battle was over, she still feels the impact of his attack.
Mine also kills Budo, the second strongest general after Esdeath.
