The Bird Mask
I think the Bird Mask is for the Water nature heart. Based on what Shikamaru's dad said:
Kakuzu's natural elemental affinity for his heart is Earth nature. So,
1. When Kakashi stabbed Kakuzu with his "Lightning Cutter", he destroyed Kakuzu's Earth nature heart, and also damaged Kakuzu's Water affinity Bird Mask (the Water nature heart itself remained undamaged).
2. In order to keep living, Kakuzu replaced his damaged Earth affinity heart with his undamaged Water affinity heart.
3. The creature with the Bird Mask then died shortly after it came out of Kakuzu, since it had a broken mask and no heart to sustain itself.
4. (Anime) Since he was now using his Water affinity heart, Kakuzu could now use effective Water jutsus.
- I actually proposed a very similar thing here just a short while ago, but I'm glad to see someone else has proceeded down the same line of reasoning. Although I don't believe there is enough evidence to confirm that the mask houses the water affinity heart, it does seem to corroborate that idea, meaning that at the very least this page does need some revisions.

- Ya, I know. What I'm saying is that Kakashi destroyed the "Earth" nature heart, and only damaged the Bird Mask, which normally uses the "Water" nature heart. The "Water" nature heart was located at a different location from where Kakashi stabbed, so it remained undamaged. Since the Bird Mask was damaged and wasn't useful anymore, Kakuzu used the "Water" nature heart, which was supposed to be used by the Bird Mask, as his replacement heart. --Cidem1324 (talk) 00:39, March 4, 2011 (UTC)
Final Mask Element
The final mask is now labelled as having Earth-element however this is wrong its actually water-element.
When Kakashi used Chidori he said earth is weak against lightning. This doesn't mean the mask was earth, it simply meant that the earth technique Kakazu was using was weaker then Kakashi's lightning technique.
Since Kakuzu was still able to use earth techniques after the Chidori that means that the destroyed heart wasn't earth. That combined with the fact that Kakuzu didn't use any water techniques means the mask was indeed water.
So can the mask be changed? Or do you guys want to wait for Manga to probably show what that mask can do?
- It's because he doesn't use water jutsu at all in the manga. If the mask ends up using water jutsu in the manga then then it'll be changed, but at the moment it would be assigning an ability he hasn't displayed yet. ~SnapperTo 22:42, March 24, 2011 (UTC)
- I've seen many gameplay videos of that game, and I found a list of the techniques you can use while playing as Kakuzu, not one of them is a Water Release. Omnibender - Talk - Contributions 17:57, December 15, 2011 (UTC)
The Final Mask, again
I came here because like others in the past two years, I was also confused as to why Kakuzu's broken mask as labeled as an Earth Element when it always struck me to be the Water Mask.
I saw above that the reasoning for this was that we never see him using Water jutsu, but shouldn't that justify it more? We know Kakuzu had five hearts so he could use all five elements. Before he brings out the masks, the only element he's seen using is Earth, implying that was his own heart. Since we never saw him using Fire or Lightning or Wind element until he brought out the masks, it's most likely that the broken mask was the Water heart and it died before he could use it.
Regardless of whether or not that's agreed with, I think the part of the article noting this mask to be Earth-natured should be changed. If the above is considered to be no evidence to suggest that it's Water-natured, there's none to suggest it's Earth-natured either. Instead it should be left as unknown, or noted that it could've been either one. --22.214.171.124 (talk) 00:37, February 27, 2013 (UTC)
In the anime, he was able use both Earth and Water jutsu without any masks. Using the five basic chakra natures requires knowledge, not any sort of genetics. Even if he lost his "earth heart", it wouldn't stop him from using Earth Spear and he was even referred to as an Earth Release user during the war. There have even been non-canon sources (video games) that specifically refer to his fourth mask as "Water Mask". The heading should probably changed to just "Fourth Mask" to avoid any speculation though.--BeyondRed (talk) 05:09, February 27, 2013 (UTC)
