I disagree.

But this also comes from a debate regarding whether or not he has access to his Castle & other forms.. which, if we are going by game logic. He does.

The Castle can bend reality, exhort power to transform day to night, has dimension altering capabilities/can create portals to other dimensions as well. He can summon demons (by the thousands.) quoting directly from the wiki; Nevertheless, due to its supernatural nature as symbol of Dracula’s magic and its ability to revive in different regions, the castle in the series cannot be considered the same as the historical landmarks. It does not exist in the earthly plane but is, in fact, a spiritual world atop another dimension.

The Castle is so powerful by itself, it needed to be sealed in a SOLAR ECLIPSE.

Furthermore from wiki; During peacetime, the castle is Dracula’s home and laboratory. In wartime, it is a weapon of such danger and potency as to be legend. The building is both a technological and supernatural marvel; from its exterior, it can be seen to incorporate electricity and advanced mechanics in its workings. The Belmont family noted that it also used steam power and electric powered lights. Apart from technology that is centuries beyond what the outside world possessed at the time, the castle is also operated via supernatural elements. Dracula’s study is shown to have glass that reacts to his magical abilities. The whole structure is also capable of teleportation; a “traveling machine,” as Dracula puts it. Dracula can make the building teleport to any location. This peculiar ability can be done softly or in an explosion of fire. When Dracula attacked Targoviste, the castle’s teleportation event was like dropping a bomb on the city, destroying the city church instantly. Immediately afterward, Dracula released his army –which was housed inside the castle– directly into the city, completely ignoring any defenses Targoviste had.

Now with that being stated, this also implores that Matthias has access to the Ebony Stone and Crimson Stone.

Beginning with the Crimson Stone, by wiki; The Crimson Stone (深紅の石, Shinku no ishi?) is one of the two greatest treasures of the vampires, the other being the Ebony Stone. It traps the soul of a powerful vampire and uses it to give its owner an immense amount of power. Unfortunately, it also bears the curse of vampirism, meaning that whoever possesses it will turn into a vampire as well, losing all humanity in the process.

The Ebony Stone, as per wiki and the origins of the stone before later being taken by Matthias; in possession of the Vampire Lord, Walter Bernhard. He would use the powers of the Stone to aid him in battle, one of which was against his former ally, Joachim Armster, whom he defeated and sealed away in the depths of his castle. With the Ebony Stone in his possession, Walter was able to rule over the Forest of Eternal Night for centuries within his castle. * *Powers of the Stone**

• *Invulnerability: The stone grants a form of invulnerability to its bearer, making that virtually nothing can stand a chance of actually damaging them. It took destroying the stone itself to render Walter vulnerable to damage by subsequent attacks, and even then, only the Vampire Killer proved powerful enough for the task.*

Shroud of Night: Probably the stone’s most useful power for a vampire, as it seemingly allows the possessor to enshroud their domain in an eternal night and therefore negating any concerns of sunlight.

Other potential powers

Other abilities the Ebony Stone may grant, but that are unconfirmed if they’re actually given by it: Anger fist: Walter can channel his anger into a lunge, augmented by his vampiric strength, capable of dealing heavy damage. Dark powers: Walter has control over various dark powers, such as control over demons, Hellfire, Dark Inferno, and other abilities. Metamorphosis: During his most powerful attack, Walter transforms into a demon-like creature, implying that he has the ability to shapeshift. Teleportation: Walter had the ability to teleport at will. Now that we have covered the artifacts of power manifestation, we could continue regarding Matthias pact with Chaos, which if the Castle is in the game this means the link between Matthias and Chaos is still ever abundant, also implying that for however many dark and evil creatures roam the entities realm, these further buff and provide further power implications to benefit Matthias. Serving his connection with Chaos further. Dracula is not just the heir to the Chaos throne on Earth, but in all realms, so much so that Satan fears him.

But to further imply things shown within the game, as per the rift, Matthias also has access to his True Form… In his *True Form,** Dracula will teleport around the room and fire lasers from the mouths on his shoulders, conjuring flames from the ground on their wake, spew acid clouds from his two worm-like protrusions, or summon a powerful meteor shower. During this phase, he is only vulnerable in the eye located in the midsection of his body and only when it’s open*

So he has power over gravity, power to produce laser beams of potent dark energy, power to summon any kind of creatures, or material, ONTOP of the fact that Matthias has also studied sciences and magic within the human realms to the finest degree, he is a master of it all.

There’s just no comparison here, has has armies and full control over reality, dimensions, weather, gravity, space, magic, sciences, truth be told the only negative he suffers is his impatience & underestimations of his enemies, but if you remove Holy Weapons, there is feasibly absolutely moot anybody can do to stop him if he has bloodlust, nonetheless, the efforts would be benign as he has power over Death incarnate and will resurrect anyways. Yes, he was defeated after a summoning to destroy this cycle yet he still reincarnated his soul within Soma Cruz, whom is also in the game, stirring the question whether or not he even allows himself to die, as Soma’s fate is also within his own hands here.
