Morbius is one of the famous characters of Marvel who got powers out of a failed experiment as most of the characters originate. There are few characters for Morbius to worry about.
Characters that Morbius must be careful of :
In the MCU, Dracula is the strongest and the worst Dracula one can ever see. Though Morbius is also a transformed bloodsucker he would nowhere a match to that of the Dracula.
WEREWOLF BY NIGHT :
Werewolf is a Gothic fiction. It has a very huge record of defeating vampire and werewolves. With a human name as Jack Russell, when the moonlight comes he turn himself into a werewolf which is very strong physically compared to Morbius. But the scientist can outthink and beat the Jack Russell.
She is the queen of monsters. Besides being so physically strong, Shiklah can even shift into any shape and has great mind control abilities, magical flames power.
Originally Franken Castle. Even the turning himself is also a science experiment gone wrong and this was done by none other than Morbius. The mad science that has actually created Franken-Castle can now turn him into just another pile of unstitched corpse flesh.
Ghost Rider :
He is one of the most powerful horror characters in Marvel. He has got the spirit of vengeance and weaponized hellfire, the ability to summon chains to flog their enemies. So clearly we can see just by sight that ghost rider far more powerful than Morbius.
The blade is the deadliest vampire hunter in the Marvel. In this long time blade must have killed Morbius but he couldn’t. So it was clear that Morbius’s scientific powers have surpassed that of the Blade. So he could just be prey for Morbius.
The dangerous devil of all. So when it comes to power physically or magically nothing could surpass in front of Mephisto. So it would just be safe for Morbius make a bargain in exchange for mercy.
As an alien gets attached to a human it can change its shape and has a great power to enhance strength. But Morbius can use his knowledge in science and can simply take off the alien off forever from the living being. So clearly Venom could a prey for Morbius.
Other than fearing to this greatly powered God no one could match his power. So there is a lot of difference in the powers of Morbius and Dormammu. So Morbius could just be safe with him.
Most famously known the villain for spiderman and seen in the story of Kraven’s Last Hunt he is a rat-like a man-eater lost his humanity and left all alone. Vermin could be physically strong than Morbius but it would be so easy for Morbius to kill Vermin by sucking his blood.
