Muhammad Al-Damin began work at the Dagan Unit as a technical support officer and first stepped into the Rainmaker Armour during an attack by Fatwa. The terrorists had struck at the Unit's headquarters and killed one of the pilots, leaving one Rainmaker Armour inert. Al-Damin took the opportunity and assisted the other Armour in the short but fierce firefight. After the conflict had passed, Al-Damin was given the opportunity to take on the role permanently. He has since shown a deep affinity with the Armour.

Al-Damin is an uberhuman with the ability to manipulate technology. Some call him a technopath and it is this affinity with machines which has enabled him to become one of the best pilots to take on the Dagan Armour since 1992.

Al-Damin is something of a perfectionist and expects others to maintain his own high standards. He can be critical of others, but doesn't see the conflict this can sometimes cause. Some people call him naive, but he is hardly that - having lived through some harrowing times since first donning the Rainmaker Armour. His appearance is somewhat disarming. His eyes are wide and searching, giving the impression of innocence. He doesn't take much attention of how he looks, but others have commented on it and have assumed that because he looks innocent and naive that he must be. Al-Damin is a smart man with an affinity with technology.

"Ooh that's going to take me an hour to fix... Can you stop throwing the bad guys around like that? A simple nitrogen spray will immobilise them - and avoid the unnecessary damage you're doing to the base."

Al-Damin is an uberhuman able to psionically re-arrange technical components and spare parts to create functioning machines. He has always had this gift but has been trained in its applications since joining the Dagan Unit. He has shown an ability to create a laptop computer, a portable radar and Geiger counter, as well as various weaponry in the field.

Out of the armour, Muhammad Al-Damin appears to be a lithe man in his thirties with short dark brown hair and large pleading eyes. He generally wears his police uniform but has times when he is more comfortable in a t-shirt and cargo pants.
