Hi again folks, I'm back, and lord willing I can answer a few more questions!
Care to educate us about the Twelfth Imam - the Mahdi?
Well Imam Mahdi is something majority of Muslims believe in (shias/sufis/sunnis...etc).
He's an individual that lord willing, will come at the right time to lead the world out of chaos and deception caused by the antichrist (dajjal). He'll reveal the truths about our universe. He'll be alongside the Messiah, as Jesus will defeat the antichrist.
Many eastern religions have talked about him... a savior that will come and remove all forms of tyranny and oppression-- then install justice and peaceful equality around the world.
Zoroastrian religion have Saoshyant http://en.wikipedia.org/wiki/Saoshyant
Hindu religion have Kalki http://en.wikipedia.org/wiki/Kalki
Buddhism religion have Maitreya http://en.wikipedia.org/wiki/Maitreya
Maybe at a latter time, we can start a new thread and talk about Eschatology in both Islam and Christianity. I'll try to find good resource on this topic to share with you.
Just remember in Islam we believe that Dajjal starts it's wars against mankind spiritually, with the help of jinns. Then in it's final stages of it's agenda (ruling the whole world by manipulating the cultural norms of all societies) he'll come in a physical form (will have one eye, and only people who are pious and have spiritual discernment will recognize he's the antichrist/dajjal).
At the same time, imam Mahdi will be fighting this creature... he'll fight him spiritually (with maybe the help of armies of angles and/or jinns), he'll fight physically (when the time is right).
In the end we believe that good will defeat evil, so Imam Mahdi and Jesus will win at the end of the day and the some important divine truths about our universe will be revealed.
