Hey everyone,Ian is not my real name but its a pseudonime,so you can call me simply by this name,well i wanna show to you guys my theory about Jason and a chronology.
i'm not sure if this is definitive,but i think Jason part 1 was drowned but not to death,and as a mentaly diseased boy turned into a survivalist kinda deal for the 20 years Crystal Lake was closed and managed to survive on the nearby woods with regular plants and animals,and robbing what he can find to survive and build his shack,than the events of 1979 he saw his mother and alice fight from the woods and could only saw his mother death before he could talk to her (presumably seeing just some part of the murders that she commited) ,and with Alice in the boat he picked up his mother's head and machete and followed Alice to take revenge some months later (the scene on the lake was a dream by Alice).
Than in part 2 he have the memorial from his mother,and take revenge on Alice,than he came back to his shack and influenced by his mother actions in the past turned into a killer of the region of Crystal Lake,and as a mentally diseased boy-like grown adult he cant feel the usual pain as a regular human without mental diseases,so this can explain his survivalism to quasi (but not totally) fatal injuries on part 2 and 3,needing just some time to ''recover'' .
A year before the events of part 3 Jason found the protagonist in the woods and scared her,but she managed to escape,and when she came back,he notices the movimentation on the nearby little farm and goes to his second mass kill,and almost died but recovered on a morgue of his wound on the head mistaken as dead (again) and came back to the events of part 4.
In part 4 he definitely dies as a human by A REAL FATAL INJURY on the head after his third mass kill.
And then in part 6 he comes back as a zombie,ressurected by one thunder,and having multiple mass killings until part 9 that he is torn into pieces by FBI and after posesing multiple bodies as a spirit he manage to recover his body and get finally killed by being pulled to hell.
I consider the events of Freddy vs Jason being before of Jason X,so Freddy revives jason as a zombie again,and after Jason escapes of being killed again,and finally dies after the events of Jason X (being burned on athmosphere).
Jason's reboot its a different timeline so not include it.
Well,thats it,if some plot holes are in it,please answer
