Lets look at Super Skrull's AWESOME powers and abilities and remember that all his FF powers are augmented making him more powerful than the FF.
Powers and Abilities:
Skrull Shape-Shifting: Like other Skrulls, Kl'rt is a shape-shifter. Thus he has the ability to rearrange the molecules of his body at will into any form, shape or being perceived that he chooses. This allows him him to imitate the appearance of any of the four members of the Fantastic Four, as well as their powers.
■ Hypnotic Gaze: The Super-Skrull possesses certain hypnotic abilities, the limits of which are unknown.
Fantastic Four Power Mimicry
The Super-Skrull has been bionically re-engineered to possess the combined superhuman powers of the Fantastic Four.
■ Cosmic Energy Power-Receptors: His body has been surgically implanted with numerous power-receptors able to gather the same cosmic energy that mutated the Fantastic Four and mimic the functions of their powers.
Thus he can thus mimic the power-sets of;
■ Pyrokinesis: The Super-Skrull possesses the mental ability to control ambient heat energy and the physical ability to transform his entire body, or portions of his body into a fiery, plasma-like state of will.
■ Plasma Form: The Super-Skrull possesses the physical ability to envelop his entire body or portions of his body with fiery plasma without harm to himself.
■ Fire Manipulation: The Super-Skrull can generate shapes composed of fire from any point on his body, such as long streams of fire.
■ Flight: The Super-Skrull with mental stimulation of his flame can form a jet of fire from his feet, directed behind him, which allows him to achieve flight.
■ Heat Absorption: The Super-Skrull can absorb infinite amounts of heat.
■ Superhuman Strength: The Super-Skrull possesses superhuman strength beyond the natural limits of the finest Skrull. Kl'rt's superhuman strength is sufficient enough to lift approximately 85 tons.
■ Superhuman Stamina: The Super-Skrull's muscles produce less fatigue toxins during physical activity than the muscles of normal Skrull.
■ Superhuman Durability: The Super-Skrull is far tougher and more resistant to injury than normal Skrulls.
■ Invisibility: The Super-Skrull possesses the mental ability to manipulate ambient cosmic energy for a variety of effects, including the rendering of himself and other objects invisible, and the construction of solid, invisible force fields.
■ Psionic Force Fields: The Super-Skrull, through concentration, is able to project a field of psionic force which he can manipulate into a number of relatively simple forms; rectangular planes, cylinders, globes, domes, cones, etc.
■ Plasticity: The Super-Skrull possesses the ability to convert the mass of his entire body into a highly malleable state at will.
■ Elongation: The Super-Skrull can extend his limbs, torso, or neck to great distances. ■ Grappling: The Super-Skrull may restrain opponents very efficiently by using his elastic form to entangle them.
■ Movement: The Super-Skrull can move at great speeds by stretching to his destination.
Cosmic Energy Power-Receptors
His body has been surgically implanted with numerous power-receptors able to gather the same cosmic energy that mutated the Fantastic Four and mimic the functions of their powers.
Because Skrulls are no longer evolutionarily susceptible to mutation, the Super-Skrull's superhumanoid powers could not be derived naturally. His body's artificial power receptors gather ambient cosmic energy and are dependent upon his immediate access to that energy for their power level. Thus, the Super-Skrull's artificial powers vary in degree.
■ Earth: On Earth, dependent solely on the cosmic energy that penetrates naturally through Earth's atmosphere, the Super-Skrull was only about half as powerful as the members of the Fantastic Four were at the time he first gained his powers.
■ Skrullian Power-Beam: Supplied with additional cosmic energy from the Skrullian power beam (whose source is a large cosmic power transforming satellite in orbit around Tarnax, the Skrull system's sun), the Super-Skrull could surpase the ability levels of all four members of the Fantastic Four.
■ Current Augmented-Power-Level: The Super-Skrull's abilities have since been augmented so that he no longer requires the power beam. His powers are actually greater than those of the Fantastic Four, for example, unlike the Human Torch, he can manifest his flame in space.
■ Stamina: The Super-Skrull's enhanced stamina permits him to use his powers to peak exertion (regardless of what that peak level currently is) for up to an hour before fatigue seriously impairs them.
■ Power Combination: The Super-Skrull can use any combination of his Fantastic Four-like powers, including all four of them at once.
■ Skrull-Military Training: The Super-Skrull is an excellent hand-to-hand combatant, having been extensively trained in the art of warfare by the Skrull military.
■ Aviation: Kl'rt is trained in the use of the advanced warp-drive starships of the Skrull-military.
■ Unarmed Combat: Kl'rt is trained in the unarmed combat of the Skrull-military, he is also quite experienced; due to his involvement in the Kree-Skrull War, fighting the Fantastic Four, and the Annihilation Wave.
■ Marksmanship: Kl'rt is trained in the use of the ranged energy-weaponry of the Skrull-military.
■ Creative Power-Use: The Super-Skrull is more creative in the use of his powers, when compared with the Fantastic Four (i.e. decapitation).
■ Leadership: Whilst in the Negative Zone, Kl'rt was able to amass an army from the former prisoners of the UX-73 Prison Planetoid.
■ Original Strength Level: The Super-Skrull originally possessed the same level of superhuman strength that the Thing possessed upon initially gaining his powers. Hence the Super-Skrull could lift (press) approximately 5 tons.
■ Skrullian Energy Strength Level: When exposed to the Skrullian energy broadcast beam, he could lift (press) approximately 15 tons.
■ Current Strength Level: The Super-Skrull's powers have since been augmented, allowing him to lift (press) approximately 85 tons.
Lobo has muscle but not brains. He big and clumsy compared to the Super Skrull who also has military experience therefore he will know how to sneak around, track, and strategize. Kl'rt also carries with him long ranged military weaponry. Even though he doesn't need them, the military weapons will come in handy here.
"Oh, but Lobo is possessed by Eclipso!" is probably what you're saying. Well, thats more of a problem for Lobo than it is for Super Skrull. See, Eclipso can only be summond by a lunar or solar eclipse. There is no eclipse happening on Hoth. Also, Eclipso cannot survive bright light neither natural or artificial so, even if there is an eclipse or the battle takes place at night, Kl'rt simply has to light up the sky with a NOVA FLAME and that would drive Eclipso right out of Lobo's body. It would also pretty much melt Lobo where he stands.
The Nova Flame is one of Kl'rt's main weapons but he wont have to use it because the LoClipso will have enough trouble dealing with the regular heat and bright light coming from SS. That there would keep Eclipso at bay.
The Thing's powers combined with Sue's invisible force fields are more than enough to subdue Lobo himself. Lobo's brain wrapped up in an invisible force field would be easy to crush. Or, a field around his head cutting off all air would also subdue Lobo quite easily.
This environment is perfect for Lobo since he can turn invisible. Lobo would not know where to look so he decides to wait in a nice and cozy Wampa cave and decides to let Kl'rt come to him. Kl'rt finds Lobo when he hears that woman like scream from Lobo when a group of Wampa's come home from a night on the town and discover the main man helping himself to some left over Tauntaun.
Just a reminder here. Some highlights in red but read it all so you understand the power Lobo is facing here.
