This is stupid Batman couldnt kill swamp thing with 100 years prep unless he was willing to somehow destroy the earth.

LMAO, Swamp thing just stands there and watching Batman breaking his fist.

Spite...Swamp Thing Owns.

Swamp Thing already won. What Swamp Thing issue was it?
BB

ah yes:

BB

Swamp thing is a top level character in dc, without destroying the planet even superman, the flash or wonder woman would go down.

Swamp thing wins.

swamp thing already defeated batman 2 times IIRC and batman had prep

Actually... Despite being a big fan of almost anything Vertigo, I do see one way for Batman to win this one:

White kryptonite. It pretty much kills all plant life It's used on. And I'd say it'd totally be Batman's style to use it...

Swamp thing wins
