Hashirama is indeed a mystery, but I believe i have officially listed everything he has been hinted/shown in the manga of what he can do!
There is allot of ppl who do not see what hashiramas wood release can achieve. And many of you think you know the reason why hashirama's wood is good by saying "it can tame/control Bijuss", but really thats the beginning and he doesnt even use that in his fights so i dont even count it.
- wood clones http://www.narutobase.net/manga/Naruto/293/9 ,http://www.narutobase.net/manga/Naruto/290/12, and one was used too follow oru, kabuto, and sai too oru's hideout. (which is better then a regular shadow clone considering its more solid http://www.narutobase.net/manga/Naruto/301/13)
- water and earth jutsu's (the lv of which we can assume is high lv),
- could make wood come from anypart of his body http://www.narutobase.net/manga/Naruto/309/10 , http://www.narutobase.net/manga/Naruto/308/3, which would be good to make immediate weapons or shields or to subdue anyone http://www.narutobase.net/manga/Naruto/494/15 http://www.narutobase.net/manga/Naruto/309/8. And Note how strong it is, yamato was able to subdue 4 tails with it http://www.narutobase.net/manga/Naruto/296/10
http://www.narutobase.net/manga/Naruto/120/7 could muster up a forest in seconds, and subdue any ninja with in with a powerful bind that is hard to break (note even sarutobi new that he needed Emma to break the wood with staff mode)
- could trap you in a fortress like trap in seconds http://www.narutobase.net/manga/Naruto/122/4
- he could use his wood to suppress the power of bijuus
- could change the landscape http://www.narutobase.net/manga/Naruto/396/10, http://www.narutobase.net/manga/Naruto/316/4
- and huge (i mean huge!) chakra reserves. And hell the 1st hokage was the one to build konoha (atleast did the hard part.lol)
- can use it to help fight. Such as ride the wood
- Heal from anything damage you may cause him almost instantly!
- Once Wrapped up, he can surpress your chakra! http://www.narutobase.net/manga/Naruto/508/2
Zetsu power added bonus that shows Wood ability
http://www.narutobase.net/manga/Naruto/512/6. tobi is using the power of the tailed beast and the 1st hokage to multiply and create the zetsu clones http://www.narutobase.net/manga/Naruto/512/9. and kabuto says he can use yamato too make more zetsus clones http://www.narutobase.net/manga/Naruto/514/17. http://www.narutobase.net/manga/Naruto/545/3
- Become one with nature http://www.narutobase.net/manga/Naruto/526/6, so could yamato http://www.narutobase.net/manga/Naruto/456/12
And lastly http://www.narutobase.net/manga/Naruto/561/11
So basically he could make a forest. Then could merge with the forest and pop up from any part (or tree, that he created) and atk you with his added other powers:
- high lv genjutsu (bringer of darkness/infinite darkness)
- water and earth jutsus
- secret scrolls (as noted being used to fight against madara uchiha) http://www.narutobase.net/manga/Naruto/399/10
- etc etc
What has been shown from Zetsu!
- Mokuton (Wood Style).. Although they are a weaker versoin of the first wood style is still wood style. lol and the ability to change the battle ground enough to your liking is great http://www.narutobase.net/manga/Naruto/545/3.. And as you can see right here http://www.narutobase.net/manga/Naruto/562/9 he can grab you anytime he please!
- Instant Travel Anywhere.. http://www.narutobase.net/manga/Naruto/396/7 not Space time nin, but a close second! http://www.narutobase.net/manga/Naruto/526/6 hell he's technically eveywhere/anywhere.lol
- Super sensor.. For awhile i was lost in how he could appear anywhere (i.e. where ninjas he don't affiliate with are, naruto and company), but its because The Earth is basically his sensor Tool! He could sense anyone (outside super barriers.lol) instantly. http://www.narutobase.net/manga/Naruto/536/11. So No matter where you go (minato, hanzou, etc) he could find/follow them.
- Durability.. YOu basically cannot kill him with direct contact! http://www.narutobase.net/manga/Naruto/536/5 Was kicked thru the chest and was still ready to fight. Neck broke http://www.narutobase.net/manga/Naruto/460/2. Slashed in half and was still alive http://www.narutobase.net/manga/Naruto/562/10.
- Super strength.. http://www.narutobase.net/manga/Naruto/604/4 destroying a boulder with one punch!
- Great speed.. As noted by sasuke, he didnt know zetsu was there until he literally seen him help him http://www.narutobase.net/manga/Naruto/486/3.
- Chakra Absorption.. http://www.narutobase.net/manga/Naruto/466/10 With his spores that not even AO's byakugan or KArin's sensing abilitys could see or sense he could let them go with out you knowing then grow on you holding you still http://www.narutobase.net/manga/Naruto/466/15 and absorbing your chakra and taking for him self! http://www.narutobase.net/manga/Naruto/466/9 BOSS!!!
BAsed off the manga (NO HYPE) He is capable of everything i listed and More! Is he the best? Is he not that broken?
What would you rank him out of Nagato, Madara (EMS Prime State), Current Naruto, KAbuto at prime time state, Obito At his best, EMS Sasuke, Itachi Healthy, Muu, 3rd Raikage, Minato, Sarutobi Prime Time State, Edo Madara
