Well, you can never convince me that magma or ice can be compared to LIGHT. the purest form of energy that exists. Its the source to all other forms of elements and well, life.
im assuming the 3 are equal in strenght and haki. but the pika pika no mi is hands down the most useful logia in the series second to the yami yami, placing Kizaru above the others in terms of potential. but he is so lazy you could accuse him of being a case of underused overpowered DF.
akainu is probably the most dangerous in melee combat, as he can turn most of your insides into coal with one punch, and even hitting him is suicide without strong haki.
But Kizarus Kicks are not something you want to face either since his light speed collision force combined with haki is a very powerful technique. and his fruit is hands down the most versatile. Its the ultimate fruit for travel, as nothing moves faster than light. his light beams are also very scare considering he can blow up several buildings with the force from one little beam, and his accuracy is perfect without having to take any time to aim. taking out luffys key to aces cell is a testament to his accuracy, but also how absent minded he is as he could just as well have aimed for Luffys heart, killing to flies in one hit. 3 if you include the manga with luffy being dead.
he also managed to keep up with the roger pirates swordsman.
and unlike other elements light has no natural weakness other than darkness wich goes for every logia. not like fire countered by magma, snow countering smoke and so on.
the only weakness seems to be that he cannot turn into pure light and move around as an intanglible element, wich makes sense since light always travels in a straight direction until its reflected. When he does transform he seems to turn into a beam, that constantly travels at a high speed bouncing around buildings.
Its probably my favourite fruit. i just cannot buy that some people would rather pick Ice over mofockin LIGHT. its like having the power of a star vs the power of a really cold antarctis winter.
Kuzans logia would be my last choice (except for the swamp one of course) i love the character but it seems like a very rigid logia. being immune to the weakness of falling into water is the main advantage over other logis i guess. But overall, i actually thought Monet did way more cool and creative things with the snow fruit and made it look more useful, altough she was obviously a perfect example of a monster fruit wasted on a total physical and mental weakling.
Its like, well, he can throw ice spears and freeze people upon contact (but apparently strong characters can break free as proved by doflamingo). Saving Marineforce from WBs tsunamis with Ice Age was rather cool though. But as this is getting OT i guess i have to ask a question: Can Kuzan move if he turns into ice? logically it shouldnt work, And i never got how his regeneration process works eitherl Like, how can a solid matera that is shattered reform without the aid of someone with heat to melt it togheter? is any of this explained? Might aswell make Diamond a logia then while we are at it :) and daz bones steel shape shifting really seemed to function as a logia. if Kuzan can reform from shattered ice, why not promote daz bones to logia, being able to shift between solid metals for cutting and liquid metal for regeneration. T-1000 in one piece, why the hell not?
Never made much sense to me and always felt like Oda really wanted to make an Ice Fruit because he was attracted to the idea of having both magma and ice fighting back to back but didnt quite know how to pull it off himself.
