At first I was only slightly aware that Cyclops had a brother. I had watched a bunch of the cartoons growing up, read a few of the comics, and Cyclops was one of my favorite characters. I watched all the movies, I own every single X-men movie, I will admit here are always a few inconsistencies in movies, like the age difference between Scott and Xavier, but for the new timeline it made sense.
When they did the new X-men First Class and added Havoc as a character I was slightly confused. At first I believed that Alex was Cyclops brother, so I was slightly worried about the timeline, because that would make Alex 68 currently and we know as we are the X-men community that that is unreal as he is the younger brother of Cyclops/Scott.
I am worried how they will tie that in even though they are saying that Alex is independent of Scott, I was wondering if perhaps they will arrange for Alex to change his role as a cousin or uncle of Scott or even perhaps his father. In X-men First Class, havoc is in his late teens early twenties that is in 1962, in Wolverine Origins, Scott is portrayed near the very end and he is in his mid-to-late teens,this takes place in 1981. Probably a sophomore or junior in High school. Scott is most-likely 16 in wolverine origins, in 1981 which mean he was born in 1965 which would logically make him the appropriate age he is in the present-themed films of X-men. Havoc is between 17-22 in 1962. Which means he would have been born 1940-1945. Making him 20-25 years older than Scott. Making him too old to be a brother but logically an uncle or father figure. We could assume the two boys age much older than they should be or resist aging into elderly men. In the comics they absorb the energy of the universe and then throw it out of their bodies as weapons, we could safely assume this same energy keeps them youthful.
My true question is wether or not the next X-men movie will explain this at all, or if they will make some shorts about it, or even, add additional movies that relate the two brothers or even add their third brother into the mix. It is an exciting series, hopefully it does not get overproduce in this franchise if they were to do that.
Some slight info:
Scott suffers from a head injury which inhibits his ability to control the red beams. This coincides closely with the comic book story that the two were in a plane crash (causing the brain injury to Scott).
Alex cannot control his powers either. This is because the beams are random circular wheels that go off in every direction.
The two have a younger brother named Vulcan/Gabriel who is supposedly 10-12 years younger than Alex, but he is matured faster than he should by an incubator machine, after he was stolen from his mothers womb and the two older boys thrown from the plane believing he other had died. Vulcan appears to be older than Alex by 5-6 years.
