I think it would be Shadow because he can learn blood bending in avatar. Force Bending im thinking that's just star wars stuff and Dark matter... idk what this is I mean if it's like Toaru Majutsu no Index then sure go for that one And for the eye power the Byakugan so he can well for one: use chi to block there bending ability's two: like near-360 vision to know when someone try's to attack him he can block it and three he can evolve into the Tenseigan. And four he can see there energy... By the way will you give him energy bending?
I think It should be Fire(Heat,Combustion,Sun Breathing(Demon Slayer),cruel sun,repulsors,rediation,Colored Flames-Blue,Purple,Crimson,Gold,Reincarnation Phoenix flame,dragon flame,Destruction flame,Ifrit Jambe,Red Hawk,Annihilation flame,hellfire,purifying flame,dark amaterasu flame,healing green flame,corrupting dark evil demonic flame,soul destroying flame,Nihility flame,void destroying flame),Combustion,Electricity(Plasma,railgun,Thunder Breathing(Demon Slayer),Chidori,Kirin,Lightning Constructs,EMP,Black Lightning,Tactle Bio-Electricity,Golden Crimson Purple Bluish Thunder,Electricity Infusion,Lightning Chakra Cloak/Shunko),Water(Fist of Flowing Water/Martial Arts of Bang(OPM),Water Breathing of Tanjiro(Demon Slayer),Healing,Ice,Blood bending without that moon,Blood whip,hydro bomb,Compressed water cutter,acid,poison),Air(Flight,Sound,Vibration,Shock,Kinetic Energy,hydrogen Bomb),Earth(Metal,Sand,Crystal,Lava,Gravity,Electromagnetism,EMP),Wood and plant,Light,Darkness(Shadow),Yin-Yang,Space-Time,Life-Death,Chi manipulation(Martial Arts,Weapon Mastery,Attack and defence,Enhancement,Healing,Chi Blocking,Martial Arts,Absorbing attacks(kinetic energy) and redirecting them like Bang(One Punch Man),Sonido/Soru/Shunko,Full Counter(Physically and Elemental),Iron Body/Hierro,Seimei Kikan(Increased Metabolism,Healing,Poison and negative ailments removal and resistance to heat,cold,poison,disease,sickness,virus,darkness,evil,demonic chi,corruption,injury,pain,cuts,mind control/manipulation/brain washing,dna cloning,absorbtion,possession,increased durability,stamina,endurance,vitality,reflexes,reaction time and speed,thought acceleration,slowed down perception,genius combatant,mimicry,danger sense,enhanced controlable senses+slight repositioning of internal organs to avoid fatal wounds),Kiai/Rokugan/King Punch/Texas Smash/Detroit Smash,Hassoken,Internal Destruction,mind protection and damage restoration and recovery,Soul(Soul attacking other people's,his own soul defending,his own soul healing factor,healing other people's soul),Demon Slayer Breathing Enhancement,Nen without Hatsu,Wall/Tree/Water/Air walking and Equilibrium,Increased Blood Flow(Luffy 2nd Gear),Dragon Shot/Ranged Homing Elemental Rasengan,Spirit Purifying,Sealing,Advanced Precognitive Observation Haki,Advanced Conqueror Haki Infusion and Stealth from advanced observation Haki,Barriers,Forcefield,Energy Bending(To take away other people's bending)....also please don’t have any dojutsu and clone and other stuff.
How about this all the known sub bending can be learned over time and can combine them or have the sub element of fire be heat bending , light bending , true lighting bending or even have it so he can freely manipulate the bending arts to make complex things that appear to have a form of sapeince like fire dragon , earth soldier , and so on So for instant water bending /sub blood bending + earth bending / sub bone bending = Flesh bending He'll air bending can have sub bendings like sound bending , compression bending or vacuum bending And if he has energy bending all other like matter , dark matter , light, darkness, shadow can be achieved as sub bending for energy bending. Or have difrrent fire's that do difrent things like crimson red fire that can melt anything , green fire that causes hallucination, white fire that heals, blue fire that freezes , black fire that can consume all other fire , gold fire that can restore things like cloths , buildings, art work and so on.
Thanks for the chapter I am really looking forward to reading more and for his bending may be something that can supplement his fire bending like gas bending which would allow him to create explosions, chemical reactions and whatnot, or he could use it to counter air bending or be able to use fire in water like with fracking, so he could do so many different things with natural gas bending and he can be like Roy Mustang with his fire or Bakugou and his explosions by concentrating the level of gas in a spot then igniting it with his fire bending. Though I am unsure whether or not this would be classified under air bending.
