Sersi is a good match for Thor or the Silver Surfer. Gilgamesh gave Thor a good fight. Ikaris could put up a brief fight against the Surfer. Zuras would beat the Silver Surfer by himself quite handily.
Are you kidding me?
SERSI
Sersi has the standard abilities of Earth's Eternals, though she has focused the majority of her power into transmutational abilities and passed it off as illusion or magic over the centuries. Sersi's psionic ability to rearrange the molecular structure of objects is far greater than that of any other Eternal; the limits on Sersi's molecular rearrangement powers are as yet unrevealed. Sersi is the only living Fifth Level adept at matter transmutation (on a 1-5 scale). She has the ability to alter molecular and atomic structures of all matter including living organisms. However, she has expressed difficulty in rearranging sub-atomic matter. Sersi has a gifted intellect, and superhuman strength (which she can supplement by psionically levitating heavy objects), stamina, durability, agility, and reflexes. Sersi possesses the ability manipulate cosmic energy to augment her life force, granting her virtual invulnerability and immortality, the ability to project cosmic energy from her eyes or hands in the form of heat, light, or concussive force, and possibly other powers. Sersi is resistant against cold, disease, electricity, energy, heat, radiation, and toxin attacks. She does not age, and can only be killed if her atoms are scattered. Sersi possesses total mental control over her physical form, granting her virtual invulnerability and immortality.
That one Surfer stomps 5 seconds at most...he has shattered peoples atoms before.

The Forgotten One possesses immense superhuman strength. While the exact limits are unknown, he is known as the, by far, physically strongest of all known Eternals, save for Thanos. His strength has been shown to rival that of Thor, and Hercules. Like all other Eternals, The Forgotten One is virtually immortal. He hasn't aged since reaching adulthood and he is immune to all known diseases. Also, his body is highly durable and resistant to physical injury. He is capable of withstanding high caliber bullets, falls from great heights, powerful concussive forces, and temperature extremes without being injured. However, it is possible to injure him. He is in complete mental control over every molecule in his body, which allows him to regenerate any damaged or destroyed tissue. However, if his mental discipline over his body is broken, it is possible to permanently injure or kill him.
The Surfer has shown to be able to influence human emotion, there is no mentioning of resistance to molecular manipulation. Surfer stomps...he also stomps Ikaris.
ZURAS
He possesses superhuman strength, speed, stamina, and durability, and can fly at subsonic speeds. Zuras possesses the ability to manipulate cosmic energy to augment his life force granting him great longevity and regenerative abilities, the projection of concussive force, heat and electrical energy up to a maximum range of 300 feet. He could also use cosmic energy to create force shields around himself, to levitate himself and/or others, and to psionically manipulate molecules so as to transform an object's shape. During his lifetime, Zuras was the only Eternal known capable of initiating the creation of the Uni-Mind (the collective life-form resulting from the physical and mental merging of a significant number of Eternals) by himself. Zuras is also capable of telepathy, illusion-casting, and limited teleportation.
Seems like the best the eternals can put up against the surfer, still no mentioning of resistence to anything. 1 min and surfer is done with him. The uni mind could be a problem to the surfer, but the only eternal that would be able to create it is Zuras and that guy the surfer probably would eliminate first. Remember that he has had a week to prepare and of course got a plan before heading into battle. It's not like he rushes in and all heroes and villains of the earth jump on him at once. I reckon there will be some assasinations before the starts the heavy killing.
but the (I think) two times he's done it, he hasn't demonstrated that kind of ease or precision. For that matter, what makes you think he would benefit much from a week of prep? He's not that imaginative. What would he do with a week that he couldn't do in 1 minute?
He has done it two times because...he has morals. He is always holding back. Now what he could do in one week...a lot...like making a plan on who to assasinate first?
