The R-Men get a visitor from the future every two or three weeks at least, to save the future. Which is pretty stupid if you think about it. If the future sucks, why does not everyone in the future return to the past? Really! Think about it. If everyone came back, there would be no butterfly effect or temporal paradox to solve, because everyone would be here. And you can't even save the future, because if it goes back to the past, that's already part of the future...that means that it's part of the problem. Maybe they should just stay at home watching TV, instead of going to back to the past.
