An Eta Classification is for humans who do not possess the X-Factor in any way which will manifest in this lifetime, but whose children could be mutants, unaffectionately called breeders by certain anti-mutant groups. The children of these people could very well have the X-Factor. These people -are- however who could become altered humans, such as the Hulk or the FF.

Keep in mind that there is no guarantee that the children of Etas, much less any mutant, need have an X-Factor, which has no doubt thrilled Magnus to no end.

Examples: Moira MacTaggart and Lupo have Eta bases.

Players are limited to four characters with an Eta Class exponent.
