3.Monkey D. Luffy
5.Aang: ( I know he is not anime, but he has an interesting skill set.)
1.The powers levels, speed, durability etc. are scaled up and down to make things fair. But that does not change the order. That is, Goku is still faster and stronger than any of them. But not the speed blitz level. Fast enough to give an advantage but not to overwhelm. or aang still has the lowest durability. Same Goes for the others. Luffy cannot be hurt by physical attacks still, but blasts can hurt him.
2.Same Goes for the power ups due to changing forms. For example. Goku will not boost up out of the league by going super saiyan. But it will give him a large boost none the less.
3.They have access to every technique used in anime (with movies) and manga. Nothing else.
To be more specific:
Goku: Various Martial arts styles, Kamehameha, Kaio-ken upto x 3, Instant Transmission (Yes, He has it. Restriction: Not used to blitz anyone but can be used to surprise), Dragon Fist, Spirit Bomb (Restriction: Can hit only one person at once. Prep time as much as in Vegeta saga). Cannot fly for over four minutes.
Ichigo: Master Swordsman, Flash step, Different Getsuga Tenshous, Final Getsuga Tenshou(Yes. Usable only once, and on one person only. Loses power immediately after it.) No Blut nonsense.. Cannot keep reishi jumping for over two minutes (but will not fall to his death afterwards. Will have to land).
Luffy: His Rubber Attacks, and Haki (Yes. Restriction: No K.O. Only fleeting prediction. He cannot find the exact nature of attacks and strategy etc)
Aang: His Martial arts, and has mastered all four elements. Cannot Blood bend. No taking Bending away.
Naruto: All his annoyingly varied number of skills. Can use Shadow clones, Tranformations, Taijutsu and Ninjutsu, Different Rasengans, Rasen shurikern, Summons. (Yes. All summons. But he cannot maintain them for more than two minutes, and cannot use them for 10 minutes afterwards. Sage Jutsus: All of them. (Including the Frog song. Restriction, It cannot be used on more than two opponents at once, needs as much prep as needed as usually needed, and can paralyze for 5 minutes only. Also, it can be used again after 10 minutes only)
4. The energy system of all four universes is compatible. That is, Goku's chi sensing will work on all, and everyone can be affected by Genjutsus etc..
Goku: His staff.
Naruto: One extra strengthened kunai to fight, 20 kunai, shurikerns and other standard Gear. It does not stop him from fighting freely.
Ichigo: Tensa Zangetsu
Luffy: Standard Gear? shorts and straw hat maybe?
Aang: One staff and his Glider.
6. Mastery over Forms: They can use the forms shown in the images
Goku can access ssj 1,2,3,4 for 4,3,2,1 minutes, and needs a 3 minute break to step up everytime.
Naruto has access to kurama's chakra if he's calm, without any problem. But if he is enraged, he could lose control as he usually does. (Not when he is already in fox mode etc.)
Ichigo can go shikai and Ban kai unlimited, but he can Go vizard for time equal to his last fight with Grimmjow. If he's hurt badly, he could go hollow and then vasto lorde form, but it will be out of control, and he will revert back after 2 and 1 minutes at max.
Luffy can use his Gears for 4 minute periods only. He reverts to little form after Gear three. and Gear two takes its toll on him as well.
Aang can Go avatar for 2 minutes at max. He needs five minute Gap for that to happen Again, if he uses it for over one minute. If he is in lethal danger, avatar state can triggered uncontrolled as usual. He reverts back in five minutes, and is asleep for half a minute afterwards.
Goku has one senju Bean.
Ichigo can have ino heal him once (The healing will be given half the time ino usually takes)
Naruto can have sakura heal him once. And has two soldier pills. (Same as above, but I think he could use kyubi chakra as well)
Poor luffy and aang have no healing. :( They are given a senju bean each.
Near a forest with enough land for Aang to use. Two large lakes, one filled with sea water, and other with normal water. It has small mountains, and rock pillars like in the place where aang and firelord fought. They are given a quick view of the battlefield before they start.
I Believe that sums it up. You can see that I am a bit confused about keeping it fair, excuse me for that. If you have any way to increase the quality and make things debatable, please suggest so. Also, if there are any forms, or abilities, or weapons I haven't mentioned, you're welcome to suggest. Same goes for anything I am forgetting.
Prep: They are Given general view about each others abilites, like Goku uses chi to fly and blast things, ichigo is a swordsman who slashes huge stuff, aang can use elements, naruto uses chakra for various ninjutsus, and luffy is made of rubber. Not a detailed expert analysis, but fleeting rumours. They are Given 15 minute time to strategise, and set traps, but they cannot bring anything extra ordinary in the given time.
State of Mind: They are in general character, though each is willing to go to any length to win.
Purpose of the thread is not about starting Flame wars or fanboyism, but to see how balanced each of these characters are. And to see how well they do if their scales are toned similar.
Well, If you managed to stay interested through the exceptionally long conditions,
Please state your reasons, No "Goku wins" or "naruto dies first cuz he sucks" or stuff like that.
Also, they don't team up to beat me up for anything in the world :p
