The Silent Hero is a Beast
If you actually take the time to review everything that this guy does he ends up being one of the strongest links in the entire series.
And thats without even completing a single adventure on his own. He has always had help. And he is still a beast.
Lets go by everything this guy has in his possesion, including his skills, going game by game.
One would assume that with him not being the main character, he wouldnt have main character strength. But he does. In echoes of wisdom we learn two things about the silent hero:
1. By the end of the game, he is in possesion of the level 3 sword, bow and bombs of might.
Aswell as having the energy gloves and belt, the stone anklet, and the spin brace(which might not really do much for him as you'll eventually see) as pointed out by linderrose.
2. He can stave off a literal primordial entity with a club and nothing else aswell as having a lot of stamina and skill.
To elaborate, the way in which you atain the green tunic aswell as the scrolls is by completing the enemy-boss rush mode. Which is heavy indication that Link is capable of doing so aswell. Of course we also have a cutscene with link literally whacking Null off screen with a wooden club. He is surprisingly strong. And not all Links have a Boss rush mode. Only a handful of them do, and they end up being the best swordsmen in the chain.
Sky, Time, Twilight, and Wild fit in this category. Wild technically doesnt have a boss rush mode but he does have something that might resemble it in the bitw dlc. The same dlc which has wolf link, which is the inspiration that Jojo took for Wild's relationship with Wolfie.
3. (What? Three? I thought you just said two!) Well, this isn't really something that he does, but I do want to point out that Zelda in her Swordfighter form(Which is clearly based off of link) can do a lot of crazy stuff. Now. Of course. Link cant actually have infinite arrows or spam spin attacks or anything else that Zelda can do in this form. But i do want to point out the outstanding speed in which she can perform a spin attack, this will be important later.
In this game, Link, attains a lot of the classic Link gear, but keep in mind that all of the gear attained in this game must be split between the heroes. Mainly Link and Zelda.
Let's review what we know he absolutely should have and be capable of:
1. 1. The longshot. Being the only one other than Time to have it.
2. Power gloves. He notably can't upgrade this to their known upgrade: the Titans Mitt. But given his surprising strength thats fine.
3. A Magic boomerang. He becomes one of the now four links to be have one alongside his downfall brothers and Four.
4. A Fire rod. Since Echo already has Din's fire im sure she doesnt need it.
5. A Mirror shield. One of now 5 links that have one.
6. He has lightning arrows, being the only one other than Wild to have them aswell as being the ONLY Link to have Poison. Arrows. Holy shit this guy does not fuck around.
7. Caladbolg. A two-handed, undegradable powerful longsword. Given that Silent has spent a lot of time in the still world, and all Links have shown some after effects to the magic affecting them. Its not impossible that any non sufficiently magical gear that he uses is magically degraded because of nulls power. This would explain why the weapons in CoH degrade except the fragile glass weapons which cant really degrade, much like his bismuth (crystal of might) gear, even titanium infusions degrade. Of course that might just be me thinking a little too much about things so feel free to forget about that.
2. Link is one of only 3 links (7 if you include smash (twilight, time, wind, wild)) that can perform the down thrust. Alongside the hero of Hyrule and Four.
3. In cadence of hyrule you can use various weapons, with Link being able to use all three types of swords: shortswords, broadswords, and longswords.
4. Perhaps the craziest thing this link can do is the spin attack. Its not just a normal spin attack, its the. Fastest. Spin attack. In. The. Series.
In the original crypt of the necrodancer, Cadence's heartbeat is what ties her to the beat. While the logic in CoH is a little different, with it instead being literally the beat of the music which ties your movement, the timing between both is still pretty much the same.
It takes one beat to set up and one beat to finish the spin attack. Anybody that knows music can tell you that two beats is the same as an off-beat. That means that the Silent hero can perform his spin attack literally in a heart beat. Even if you speed up the beat he can still perform it. And its not like in wind waker where link is winded either. No. This guy can do his spin attack and immediately go back to boxing. Maybe his balance is helped by the stone anklet.
Anyway he is a good swordsman.
Linderrose had already pointed out that this adventure was mainly Legend's. But there is one outfit that piques my interest. The Sword outfit. Its Blue. He actually wears it in promo art. It doesnt even have to change color to match his color scheme.
I know thats not much, but the fact that it just fits is an incredible thing to point out given that this link has never been a 3d link, yet all his games always make an effort to point out that he is a very very skilled swordsman.
This Sword Suit also gives him the ability to shoot sword beams at max health much like the sword of might also allows him to do. This ability is normally ties to the master sword, although the four sword can do it aswell.
There is also a very familiar looking ruby in his neck.
Anyways I just wanted to point out that even tho this guy has never gotten full credit for any of his adventures(As a matter of fact he keeps getting increasingly more help in each adventure), he is still very much a force to be reconned with.
ALSO HE IS ONE OF THREE LINKS TO FIGHT A GOD.
