Theory one piece

I think many individuals underrate Kid when they say he has truly no chance against Shanks; i for one trust that Kid is one of the strongest(if not the most grounded) supernovas, and the main supernova who is presently qualified to beat Shanks. 

I think Kid has the magnet natural product; this gives him the ability to make and control electromagnetic fields. This may not appear to be exceptionally great, but rather i trust it is one of the most grounded paramecias in OP. Give me a chance to clarify 

Objects pulled in to magnets are known as paramagnetic. Objects that are not pulled in by magnets are called diamagnetic. Diamagnetic items are really repulsed by attractive fields. In the event that an attractive field is sufficiently solid, it can really be utilized to suspend objects. Here are a few forces Kid could use by making effective attractive fields 

flight, repulses the ground by making an effective attractive field 

he could even coat his clench hands with an attractive field. In the event that Kid did a "magnet punch" by covering his clench hand with an attractive field; it would repulse the individual hit, as natural matter is daimagnetic, however the iron in blood is paramagnetic and would be pulled in to Kid's clench hand. The outcome? Child would have the capacity to send foes flying with only one punch, the attractive field would pull in the adversary's blood,

he could make gigantic, capable fields; this would permit him to conceivably suspend islands, then crush them into adversaries. He could even control water, as water is diamagnetic; this implies child would be an immense danger to DF clients 

he could even cover his body with a capable attractive field; this would fundamentally be similar to a power field which would repulse any diamagnetic assault, so essentially everything except for metal would be repulsed. However Kid can control metal too, so even metal wouldn't be compelling. He could likewise cover other individuals' bodies with attractive fields, this would fundamentally smash them 

Presently when many individuals say that Kid doesn't have a chance against Shanks, they appear to overlook that KID IS A FRICKIN GENIUS 

when he was a kid, he was demonstrated to know generally accepted methods to construct robots 

he even transformed himself into a cyborg 

Child's energy requires information of attractive fields keeping in mind the end goal to be utilized at it's maximum capacity, Oda wouldn't give Kid this force unless Kid had the learning to utilize it 

So if Kid is as brilliant as he shows up, then it's presumable that he has an arrangement; yet what could that arrangement be? 

I think it could rotate around pacifistas 

Child can totally control metal, so a pacifista would stand no chance against him; that is the reason i trust that child has or is wanting to take a pacifista. Once Kid takes one, he can dismantle it and figure out how to make a portion of the pacifista's innovation 

With Kid's information and power, i trust he could make a robot armed force to annihilation Shanks. With pacifista innovation, Kid could furnish his robots with lasers and sturdy metals for more power and toughness. Child could likewise utilize pacifista innovation to upgrade the groups of him and his team. Consider the possibility that Kid got to be similar to Franky. Under his skin he would have a layer of shield for better guard, he could substitute his eye for a robot eye, and even furnish his arm with lasers and perhaps even ocean stone. 

Some of Kid's group as of now seem, by all accounts, to be cyborgs, so having pacifista innovation would be a major help to their general quality. 

Presently i know this is a major consider the possibility that, however imagine a scenario in which Kid made sense of how to weaponize zoans. We realize that Kid is all around educated about underground arrangements, so imagine a scenario in which Kid effectively made an arrangement for grins. Child could give a grin to his cyborg body parts to upgrade them significantly facilitate, i mean imagine a scenario where child's arm could transform into a winged serpent. I know it's kinda far-fetched as Kid didn't appear to be frantic when he discovered that doffy fell, however it would in any case be a cool energy to see 

Conclusion: 

Despite the fact that Kid may not as a matter of course thrashing Shanks, because of his fallen angel products of the soil knowledge, it is conceivable that Kid will have an opportunity to annihilation Shanks.
