Dawoodi Bohra - how they differ than the Twelver Shia?

[Optimus Prime]

Can anyone give me any solid details.

They differ on fiqh. The fiqh of Qadi Nomani is mixture of Zaydia and 12ers. Then the main difference is Imamate.

Here is a clip where Hasanian Rajabali pretended he was one of them in taqiyyah, so he can slowly convert them into 12ers. However, he was busted, and as soon as he was caught he ran away.

By the way I have heard of many cases where 12ers pretend they are Sunni, and volunteer at Sunni mosque. Then they volunteer to help new converts, and slowly they try to convert them into 12er Shia.
