[@BrokenWashing] Great sheet. I do see that there is mention of Grundy being connected to the Green on the wiki, but I'm not sure what the explanation for that is. Do you have any idea about that? 

Beyond that, you could perhaps delve a bit more into Swamp Thing's history. Possibly mentioning his association with Justice League Dark or his archenemy Anton Arcane, but otherwise your sheet is good to go.
