So few comments? Lemme fix this. (Also, mine was shut down because the mods are big jerks.)
We are amidst strange beings, in a strange land.
The flow of time itself is convoluted, with heroes centuries old phasing in and out.
Lordran is a bleak and dismal land. The gods have left. The living are few. And the Hollows, those Undead who have lost all hope, wander seeking fresh souls. And yet, even in this Darkness, Solaire stands a symbol of hope, an unyielding companion whose presence has helped many in their Journeys, from the Bell of Awakening to the heights of Anor Londo, to even the Kiln of the First Flame itself, where it all began and it shall all end.
Also, he is a meme.
Solaire's famous "Y-pose" gesture, the same one his Amiibo is in, is well known amongst the Dark Souls Community. It is the official gesture of the Warriors of Sunlight, a "Covenant" in the game focused on co-operative multiplayer gameplay. Warriors of Sunlight leave special marks on the map using a White sign Soapstone, through which they can be summoned to aid other players in their quest in the form of a golden phantom. The community has dubbed these phantoms as well as members of the Covenant in general, as "Sunbros".
Solaire's potential kit, seems rather self-evident to be honest. His heavy iron armor and thick, non-anime build, make him a clear heavyweight, somewhere around 120~ in Smash 4 metrics, edging out Snake for the title of heaviest human. (I mean look at the guy. His outfit just looks heavy). He packs a medley of powerful defensive options, his sunlight shield could block projectiles and parry attacks, leading to a devastating counterattack, and his experience in rolling through attacks is second to none. Combine that with his access to a projectile, and he'd be the ultimate cancer.
Neutral Special Attack: Lightning Spear
Solaire's neutral special has him pull out a bolt of golden lightning and hurl it at his enemies. This attack can be charged up by up to two stages, first becoming the Great Lightning Spear, with piercing properties, then the instanteous Sunlight Spear. (The Sunlight spear is not actually instantaneous in Dark Souls, but it's also not something you have to charge up. I figured there should be some payoff for such a long-charge attack).
A miracle that launches a spear of lightning.
Said to be the legacy of an ancient clan whose leader was revered as the God of Sun.
The name of the clan has been lost to time, but the gross incandescence of our magnificent father shall never wane.
Custom Move 1: Lightning Stake
Instead of throwing the spear, Solaire slams it down, creating a large, powerful explosion. Basically it's Ike's Eruption.
A lost dragonslaying miracle.
Strikes with a stake of lightning.
This tale describes the lost practices of ancient dragonslayers, who found that in order to pierce dragonscale, lightning should not be hurled as a bolt, but rather be thrust as a stake directly into the dragon's hide, to be truly effective.
Custom move 2: Lightning Ball
Solaire throws an orb of lightning into the sky, where it steadily moves forwards, firing off bolts of lightning every few seconds. The size and power of the attack is increased by charging. In Dark Souls, this was a miracle known as "Blinding Bolt", but given it's nonindicative name, I figured a more typical one might help.
A miracle that creates a giant soul mass and transforms it into a lightning-spouting orb of light.
Crafted in ancient times by the God of Sun, but later forbidden by the same deity. Was it to protect the world from hatred, or sorrow?
Side Special Attack: Sunlight Blade
Solaire's side special is another charged move. This one has him imbue his sword with lightning, causing it to deal more damage and paralyze enemies for a short duration on every hit. This is important because of Solaire's clunky normals and relatively poor combos. With the extended openings after each attack Sunlight Blade provides, Solaire has access to a number of combos he would not have otherwise, including most of his kill options. The longer he continues to charge his side special, the longer the buff lasts afterwards.
Miracle wielded by Lord Gwyn's firstborn. Boost right weapon with rays of Sun.
The power of sunlight, manifested as lightning, is very effective against dragons.
When the eldest son was stripped of his deific status, he left this on his father's coffin, perhaps as a final farewell.
Custom Move 1: Gold Pine Resin Bundle
A much faster, but weaker and shorter-lived version of Sunlight blade. This version cannot be charged.
Rare pine resin which emits golden sparks.
Collected in a small bundle.
Quickly applies lightning to right-hand weapon.
Does not last for long, but can be used in inventive ways, such as applying it in the middle of a series of blows.
Custom Move 2: Sacred Oath
Does not provide the Paralyze effect, but instead increases Solaire's defense and knockback resistance, a key advantage when combined with his poise mechanic.
Miracle of those chosen by the Sunlight covenant.
Temporarily boosts attack and damage absorption for self and those in the vicinity.
This is the tale of the Sun's firstborn, his faithful first knight, and the brave dragonslayer who served them both.
Up Special Attack: White Sign Soapstone
Marks the ground with a white sign, then teleport to it in a flash of light on second activation. Smash activate it while on the ground to replace an already-existing soapstone with a new one.
Online play item. Leave summon sign. Be summoned to another world as a phantom through your sign, and defeat the area boss to acquire humanity. (Hollows cannot conduct summons)
In Lordran, the flow of time is distorted, and the White Sign Soapstone allows Undead to assist one another.
Custom Move 1: Red Sign Soapstone
Marks the ground with a red mark. Multiple marks can be active at once. Reactivate when an enemy is near a mark to teleport to it in a flash of light. Somewhat unreliable as a recovery option, but can be used more aggressively.
Online play item. Leaves invasion sign. (Hollows cannot use the item)
Be summoned to another world as a dark spirit, and defeat the summoner to acquire humanity.
Certain Darkwraiths resist their descent into dark and persevere along the honorable path. The Red Soapstone is for them.
Custom Move 2: Homeward
A more traditional teleport. Does not have a flash of light on arrival. Otherwise similar to most teleportation recoveries.
Great miracle cast by advance clerics. Return to last bonfire rested at.
Would normally link to one's homeland, only the curse of the Undead has distorted its power, redirecting casters to a bonfire. Or perhaps for Undead, this serves as home?
Down Special Attack: Parry
It's another counter. Joy. This one comes out fast, with short frames, and if hit by any non-projectile (including disjointed hitboxes), it "Command Grabs" the attacker (mechanically, but in appearance they're just knocked off balance for a moment before Solaire goes medieval on them). Solaire then proceeds to impale anyone that was knocked off balance, dealing severe damage, then kicking them off his sword, launching them sideways. As it isn't actually an unique ability, there's no lore I can pull. So here's Solaire's shield's lore.
Shield of Solaire of Astora, Knight of Sunlight. Decorated with a holy symbol, but Solaire illustrated it himself, and it has no divine powers of its own.
As it turns out, Solaire's incredible prowess is a product of his own training, and nothing else.
Custom Move 1: Projectile Parry
This version can deflect projectiles like Mario's Cape. Combine with passive blocking to make any projectile-based enemy's life hell. Here's the lore description for the Golden Wing Shield, the first shield most players encounter with the ability to parry magic in Dark Souls II.
A blue shield with a gold relief of wings. Likely a symbol of guardianship used by the Knights of the Blue.
Contains materials enchanted by magic, allowing spells to be deflected by parrying.
Custom Move 2: Brutal Parry
Rather than kicking his opponent off his sword, Solaire slams them into the ground, with the sword still deep in their gut, trading off the knockback ofof a normal counter for more raw damage. This is based on the unique animations and increased "Critical" attack damage granted by the Hornet Ring.
Ring associated with the Lord's Blade Ciaran, one of the Four Knights of Gwyn, the First Lord.
Boosts critical attacks.
The masked Ciaran was the only woman to serve in Gwyn's Four Knights, and her curved sword granted a swift death to any and all enemies of the throne.
Final Smash: SOUL OF CINDER
Solaire plants his sword into the ground, erupting into flame. Anyone hit by this flame is pulled into the Kiln of the First Flame to face the Soul of Cinder, who performs a brutal five-hit combo that ends with planting his sword into the ground and emitting a second flaming blast. After this, the screen fades to black, and that infamous game over screen shows up again.
Since Lord Gwyn, the first Lord of Cinder, many exalted lords have linked the First Flame, and it is their very souls that have manifested themselves as defender of the flame.
Alternatively, if the Soul of Cinder is too grim for Smash Bros, you could have Solaire summon the Chosen Undead (in his classic Elite Knight outfit), Black Iron Tarkus, and Witch Beatrice for a powerful combo attack that ends in sending the opponents skywards......into a salvo of sunlight spears from all four fighters (ignore that none of the others typically use miracles, I'm riffing on that opening scene with Gwyn vs the Dragons)
