For example, Diego García de Paredes is famous Spanish knight who fought 300 duels and never lost, climbed alone a turkish fortress's wall alone and killed dozens of men before being captured (no other soldier managed to climb the wall, so he was alone), was sent to a dungeon, broke his chains, escaped the dungeon and joined the fight again, bare-handed... in a later battle held alone an army of 2,000 frenchmen in a bridge, killing 200-500 of them (the number is unclear) forcing them to resort to cannons to drive him away from the bridge. He survived to old age and died from a bad fall while playing with some children...
The Portuguese soldier Aníbal Milhais basically defeated on his own two assaults of the German army with his Lewis machine gun, killing hundreds of them and covering the retreat of the British and Portuguese contingent; afterwards he escaped, rescued a British major and crossed the enemy lines, joining his unit. He never told what he was done, such was his humility, but other soldiers revealed the truth. A few months later he repeated the same feat, holding the whole German army alone to cover the retreat of his pals...
The Native Canadian soldier Francis Pegahmagabow killed 378 enemy soldiers and captured 300 more during WWI, and was famous for his ability to cross the deadly trenches to pass messages or retrieve ammo during battles.
The Mapuche Galvarino, after losing both hands, had two knives tied to his forearms so he could keep killing enemies in battle.
Centurion Marcus Cassius Scaeva was basically Roman Wolverine: It was reported that, at the end the battle of
Dyrrachium he had over 200 arrows in his shield and a few more in his armor and body (including one sticking out of his eye socket), and he had killed so many enemies his sword went blunt and he kept killing people bashing their heads with rocks (he survived that battle, was promoted and keep fighting during that war...).
...etc.

? With Brunhilde, it's to see how far and desperate she becomes to save humanity, how much she will give up, ie her sisters. Now, we see her admitting weakness here, right after she cried over Heracles in the previous match.
