The 12th Imam will Kill the Zaidis for rejecting him

[Rationalist]

ويسير إلى الكوفة، فيخرج منها ستة عشر ألفا من البترية، شاكين في السلاح، قراء القرآن، فقهاء في الدين، قد قرحوا جباههم، وشمروا ثيابهم، وعمهم النفاق، وكلهم يقولون: يا بن فاطمة، ارجع لا حاجة لنا فيك. فيضع السيف فيهم على ظهر النجف عشية الاثنين من العصر إلى العشاء، فيقتلهم أسرع من جزر جزور، فلا يفوت منهم رجل، ولا يصاب من أصحابه أحد، دماؤهم قربان إلى الله. ثم يدخل الكوفة فيقتل مقاتليها حتى يرضى الله عز وجل
 
Imām al-Bāqir (as) has said: ''[Then he - Imām al-Mahdī] will set out towards Kufa, then from that city 16.000 people of al-Batriyyah will confront him, armed with weapons, reciters of Qur’an, Fuqaha of religion, their foreheads have sign of prostration, their faces are yellow due to fasting, but their aim is hypocrisy, all of them will say: O son of Fatimah (sa) go back, we do not need you, so he will confront them with sword in the back of Kufa, on Monday from noon to evening he will kill them faster than slaughtering the camels. So no one from them will remain and from the companions of Imām (as) no one will get harmed. Their blood is a sacrifice for Allah. Then he will enter Al-Kufa and with fight with its fighter so that Allah is pleased.''

I don't think there are 16,000 Zaydis in all of Iraq let alone in Kufa... 

[Hani]

cuz of their hypocrisy n stuff, but 12ers are OK.

A lot of 12ers are spreading these types of ahadith because of the war which is happening in Yemen now.
