Ben Tramer is an interesting case in terms of Variants in the Halloween Multiverse.

In Universes where Michael's first attempt to kill Laurie Strode takes place in the 1970's, he almost always dies. In over 90% of those universes, he dies. That's quite a high percentage.

However, in universes where those events take place in different decades and even a year away, then he lives. That's not something seen very often, not even in the Omniverse.
