Godzilla is superior to titanous monsters and humanity while the Mind Flayer was defeated by a group of people, and a telephatic teenager. To add, Godzilla is 5 times taller than the most powerful incarnate of the Mind-Flayer.
Based on the information about the two creatures, we can say that Godzilla stands a much better chance to win than the Mindflayer does.
The many-legged creature manipulates and controls people's minds, but Vecna may be even deadlier. Fans of Stranger Things claim that Vecna is stronger than the Mind Flayer. Some claim that Vecna, in fact, made the creature because he said in Season 4, “And I found the most extraordinary thing of all.
The Mind Flayer persisted, but was overwhelmed by El's powers forcing him to retreat back into the Gate. El then sealed it, and the Mind Flayer is heard roaring in anger and defeat afterwards. The closure of the gate resulted in his influence over the Demodogs, and D'Artagnan, to cease and they all died instantly.
It's difficult to determine exactly who would win a Vecna vs. Mind Flayer fight in Stranger Things, but most signs seem to point to Vecna.
Near the end of Stranger Things Volume 1, Dustin speculated that Vecna is the Mind Flayer's “five-star general,” but the truth is nowhere near that simple. From the information we got during the Stranger Things 4 finale, we can conclude that Henry Creel is the one calling the shots; in fact, Henry is the Mind Flayer.
So, in Season 4, Stranger Things brought back the flesh and blood monsters by introducing the very-pratical Vecna, who was not only terrifying, but he was also more powerful than Eleven, hence why Dr. Brenner was so afraid of him.
Henry Creel, also known as One (001), Vecna, or the Mind Flayer, is the main antagonist of the Netflix original series Stranger Things. He will also be the main protagonist of the upcoming video game Stranger Things VR.
2 Mind Flayers Do Have Weaknesses
In fact, their own psionics can be their greatest downfall. Mind Flayers can get an illness known as “the ashen” that seems flu-like at first. It gives them dry, beige skin, impaired mental operations, and ghosts in the machine (remnants of the host body's mind).
The githyanki ruthlessly hunt and slaughter Mind Flayers, just as much as they happily kill the githzerai. The gith hate each other for their differences in philosophy and abilities, and it is rumored that if they could work together, they could annihilate their masters of old.
To add, Godzilla is 5 times taller than the most powerful incarnate of the Mind-Flayer.
The mind flayer, h, is an especially perilous type of monster that appears in NetHack. They are omnivorous humanoids with octopus-like tentacled heads, and possess flight, telepathy, see invisible, and infravision.
Despite the flabby gut, Orcus was physically stronger than Demogorgon and also came with a bunch of high-level magic powers like other demon lords. What made Orcus so unique and dangerous at the time was his special artifact, The Wand of Orcus.
Godzilla may have the superior intelligence, hax, and a stronger form, and he may have much more feats onscreen, but in terms of physicality itself, the Kraken... is simply far too powerful.
King Ghidorah is considered Godzilla's greatest rival and for good reason. He's bigger, badder, and stronger than any other kaiju Godzilla has fought. Being able to fly and having three heads, King Ghidorah proves to be a lot to handle and Godzilla usually needs aid from others to be able to take him down.
Mechagodzilla alone holds the distinction of being the monster with three wins over Godzilla, but he's not the only kaiju who's managed to pull off this difficult task. The first creature to ever beat Godzilla was actually Mothra.
Illithids have a humanoid body with an octopus-like head. They have four tentacles around a lamprey-like mouth, and require the brains of sentient creatures as part of their diet. An illithid who snares a living creature in all four of its tentacles can extract and devour its living brain.
Demogorgon is first mentioned in the commentary on Statius's Thebaid often attributed in manuscripts to a Lactantius Placidus, (c. 350–400 AD). The Lactantius Placidus commentary became the most common medieval commentary on the poem by Statius and is transmitted in most early editions up to 1600.
The Mind Flayer's main form, also known as the 'Shadow Monster', is a massive entity, looming at least 50 stories tall. It has a unique body composed entirely of minuscule particles, giving it a misty appearance akin to a shadow.
In episode 7, Vecna is revealed to be Henry Creel (played as a youngster by Raphael Luce), the son of Victor Creel (Robert Englund) and his wife Virginia (Tyner Rushing) shown in the 1950s flashbacks.
The real jaw-dropper, though, is that the season 4 finale revealed that Number One, Vecna, is not the Mind Flayer's lieutenant, he's not the Demogorgon's hellish colleague; no, he's the one calling the shots. Every single terror from the Upside Down answers to Vecna.
In a fit of rage, Henry used his restored powers to brutally murder the other test subjects and workers, and attempted to do the same to Eleven. However, Eleven stood her ground and ultimately overpowered him, sending him through a gate to the Upside Down; there, he gradually transformed into the being known as Vecna.
What is the significance of 4 for Vecna? The new season shows that the four chimes of the grandfather clock symbolize the four victims Vecna needs to claim in order to enter our dimension and take over humanity.
One Steals Eleven's Powers
Just as Henry could see into the minds of others, from the Upside Down Vecna can still see into people. The vines of the dark dimension, which have made their way to the real world, connect directly into his body.
