I have to admit I am confused by what has happened in recent years. AI am going to layout a brief history of Swamp Thing as I believe, and I know I am wrong but I am hoping I get some non-snarky help!
1- Swamp Thing starts as Alec Holland, he is transformed into a muck monster in a lab experiment.
2- years later, he discovers he is actually Earth Elemental who only thought he was Alec Holland. Alec Holland is indeed deader than dead.
3- New 52: Alec Holland is back from the dead, but has to become Swamp Thing to save earth from The Rot. This keeps his organs intact as a hybrid or something? Like, he is no longer all-plant life? Not sure what happened to previous elemental that thought he was Alec
4- Levi became Swamp Thing: He is still human, but can transform back and forth into Swamp Thing for some reason? Not sure what happened to Alec, but he is in the green or something.
Please correct me where I am wrong, and if anybody could expand on 3 and 4 so I can un-confuse myself! Thanks in advance to all replies!
