Peter: The light and the darkness has always duked it out in almost everything fiction, weather it be Lord of the Rings, Star Wars, or most video games.
John: But these two use swords that are practically alive! Link, the Hero of Hyrule.
Peter: And Nightmare, the Demonic Scourge of Soul Caliber. I'm Peter and he's John, and it's our kid to analyze their weapons, armor, and skills to see who'd win, a Death Battle.
Link:
Peter: Link's origins are mixed up as well as confusing.
John: He was born in an island in the sky, the surface down below, a forest...twice, a island with his sister and grandmother, and more.
Peter: However, one thing always remains about Link, and that he is and will always be destined for greatness.
John: If you're confused about what we're doing, we're using a combined version of all canon Links, which means no Hyrule Warriors stuff. But at the same time, we're not using ALL of his items as there's too many to fit in one Death Battle, so we choose his more iconic and powerful weaponry.

Peter: He can do techniques like the Mortal Draw, Shield Bash, Fatal Blow, Helm Splitter, Back Slash, and more. And while his swings may appear to be slow, he can actually swing his sword really freaking fast.

Hylain Shield: 
-Indestructible.

-A standard bow.

Double Clashshots:
-Can latch onto certain objects and can bring items to him.
-Can be used repeatedly one after another.
-Can move up and down if attached to a celling.
John: So this guy isn't only Robin Hood and Batman, he's also Spider-Man!
Peter: Link is also very good with magic. He has a Magic Meter that allows him to...use magic. However, if he abuses it, the magic meter will run out. Although it can recharge itself in a matter of time.
John: And Link has the tendency to use his long...smooth...trusty rods to help him out.

Fierce Deity's Mask:
-Turns Link into Fierce Deity Link.
-Doesn't have a shield, but gains a Double-Helix Sword.
--Is twice as powerful as the Master Sword.
--Can shoot energy disks from it regardless of how much health Link has.
-Canonically defeated Majora.
Peter: And...well...
John: You want to say it, don't you.
Peter: Yeah, but it was already said. I would just be copying them.
John: So? It's Death Battle. Does it really matter if you're copying someone if it's the truth?
Peter: That's...a good point. Anyway. Defeating Majora may not sound that great, but trust me, it is.
John: Majora was able to pull down the moon from its orbit.
Peter: The energy required to pull of such a feat ranges from 25.813 petatons to 1.087 exatons. I'm going to stop there for now.
John: So, Fierce Deity Link is pretty damn OP.
Peter: Not enough? Well, Fierce Deity Link is more powerful than the Four Giants who held up the moon without straining.
John: But, one of Link's greatest things in his arsenal is the Triforce of Courage.
Triforce of Courage:
-One piece of the Triforce.
-Gives Link some protection against evil magic.
--Protected him from turning into a lost soul. But it turned him into a wolf.
-Grants Link 'untold mystic abilities'. Most of which are unknown.
John: And because of these things, he's obviously gotta have some amazing feats.
Feats:
-Saved Hyrule and other lands for over ten generations.
-Defeated monsters hundreds times his size.
-Very versatile.
-Was able to wield the full Triforce in Skyward Sword.
-Can wrestle Gorons.
-Can stop a bull charging at him...as well as several Gorons.
-Survived an explosion that blasted him far enough across part of the Great Sea and hit the Tower of the Gods.
-Fast enough to beat Onox, who's faster than lighting.
-Strong enough to pull down Gohma with nothing but a grapple hook.
Peter: But of course, no one is without their weakness.
Weaknesses:
-Relies heavily on his items.
-Arrows and bombs are limited.
-The CDI games....just....the CDI games.
-Overuse of Magic Meter can deplete it faster.
Cole: That's...not a lot.
Peter: Well. That's Link for ya. Anyway. No matter how tough an enemy is, Link will more or less come out victorious.
John: Welp. Let's see the competition.
Link: *Slashes Ganon twice before stabbing him in the face*
Nightmare:
John: Almost every sword we've seen is either awesome, normal, or just bland.
Peter: But one blade in particular caught our eye.
John: Enter Soul Edge. One of the biggest sword to ever exist. Rivaling even that of the Buster Sword.
Peter: It turns out though that this sword is alive, possessed by a demon know as Inferno.
John: Unfortunately, being a living sword had its downsides. In order to conquer the world, Inferno needed a person good enough to wield Soul Edge and conquer the world for him.
Peter: Several unfortunate souls were corrupted by the sword, including a pirate. However, known of these people were the right warrior Inferno was looking for. But, that changed when a man named Siegfried showed up and wielded the demonic blade. He was then, slowly but surely, transformed into the demonic being known as Nightmare.
John: But things don't always last forever, and Siegfried was able to separate himself from Inferno's grasp. Man. What a pain. These guys could've had a fun time together. What would make Siegfried stop being an awesome demon?
Peter: Well, he did terrorize Europe for several years, killed many people regardless if they were innocent, and was mentally tortured.
John: Oh...
Peter: Anyway, despite not having a living person wielding the blade, Inferno was able to re-animate Siegfried's discarded armor and declared to hunt down Siegfried and spread his rain of chaos once more.
John: Man. What a badass.

-Vessel of Inferno.
-Can take various forms depending on the wielder.
-Malfestatuon Curse.
-Is sometimes missing four fragments.
-Supposedly indestructible.
John: Oh. He has multiple stances. That's pretty cool.
Peter: He has many fighting styles that give him an advantage over his opponents. He normally channels fire through his sword, but that's not all Nightmare has to offer.
Signature moves:
-Grim Stride.
-Dark Reconquista.
-Death Lord's Vengeance.
-Death Lord's Annihilation.
-Bloody Lord's Invasion.
-Ether Lord's Carnage.
-Grim Lord's Auto-de-fé.
John: If his opponent isn't already dead, then Nightmare has the ability to devour souls with Soul Wave. Capable of devouring hundreds of souls at once.
Peter: And as stated, Soul Edge has been fractured to the point wear four pieces of it split apart.
John: He was able to find the first three, but for some reason, the fourth piece just so happened to be forged into a holy blade known as Soul Calibur. Huh. Now I know where the name comes from.
Peter: But Nightmare was able to obtain that last piece. When he did, he was able to transform into Night Terror.
Night Terror:
-Can now fly with fire wings.
-Can shoot purple lasers from his head.
-One shotted Zasalamel, who was thought to be unkillable.
-Can utterly destroy a soul.
-Uses moves that Nightmare and Siegfried use.
-Has a flying stance that automatically repels attacks.
-Has an seemingly unblockable eye-beam projectile.
John: Talk about power! Not even reality warpers, like Algol, would dare face Night Terror.
Peter: Though on a rare occasion ifNightmare falls, Inferno will come out to finish the job.
Inferno:
-Can mimic and improve on any fighting style he sees.
-Can summon whatever sword he desires.
-Can transport him and his opponent to the Astral Chaos.
-Capable of possessions alive or dead bodies.
-Capable of reality warping and fire manipulation.
John: Well...holy crap. How does anyone best this guy!?
Peter: Well...many can. But most end up dying.
John: And his feats are a pretty damn good reason why.
Feats:
-Defeated an entire army in a single night.
-Obliterated Ostrheinsburg Castle in a single blow.
-As Dumas, thruster Europe into a continental-wide war.
-Killed Tira.
-Ripped a hole through dimensions with Soul Edge.
John: Ok. No way. NOW WAY this guy can lose to anyone.
Peter: Well, he obviously can. If he couldn't, well, then the world would be screwed already.
John: Good point.
Weaknesses:
-Inferno's existence is dependent on Soul Edge.
-Soul Edge can be broken by Soul Calibur or other holy weapons.
-Tends to underestimate his opponents.
John: Man. That's not a lot of weakness. Oh well.
Peter: It's hard to imagine a man or woman capable of even lasting a second with Nightmare.
John: With this much power, I want to question how Guts beat him.
Peter: Who knows. Well, Wiz and Boomstick know. But that's beside the point.
Nightmare: "Blood! Darkness! I shall draw the world in both!"
