And if Mandarin is the mysterious shadow broker behind the Ten Rings terrorist organization, he clearly has no interest in gathering those ten physical rings together himself, since at least two people are *known* to be wearing them.
And, if the ten rings are already here and in possession of Mandarin and/or the Ten Rings terrorist group, then Fin Fang Foom becomes redundant and is no longer needed in the Marvel Film Universe. (Which would shoot down the popular internet theory that the Avengers' "leviathan" is, in fact, Foom.)
I would disagree with some of this. The terrorist organisation 'the 10 rings' could be symbolicly named. The rings worn by other individuals (?; I only remember 1) could be replicas given to signify a position of some rank within the organisation. Neither of the ring(?s) seen have demonstrated any powers.
More than likely the Mandarin has the original 10 power rings which aid him in running this organisation.
I doubt IRON MAN comic fans would be happy with a Mandrain depicted without actual rings of tech power.
