I've never been an aficionado of the Green Lantern, and one of the things I didn't know about him, or them, since there is apparently a whole Green Lantern lineage, sometimes coexisting in an intergalactic Green Lantern Corps managed by the Guardians of the Universe, was this thing in the earlier phases of development in which his magic power ring didn't protect him from attacks with wood, or vegetable matter in general. This is blamed on the very first Green Lantern, or first one on Earth at any rate, in ancient China, one Yalan Gur. Wikipedia explains,
Power ultimately corrupted this early Green Lantern, as he attempted to rule over mankind, which forced the Guardians to cause his ring to manifest a weakness to wood, the material from which most Earth weapons of the time were fashioned. This allowed the Chinese peasants to ultimately defeat their corrupted "champion". His ring and lantern were burned and it was during this process that the "intelligence" inhabiting the ring and the lantern and linking them to the Guardians was damaged.
And the ring and lantern retained this wood vulnerability when they were picked up by the original American Green Lantern, Alan Scott, but it didn't transfer to his successors, beginning in 1959 (Hal Jordan's lantern was vulnerable to the color yellow instead, and the entire topos of Kryptonite knockoffs eventually disappeared from the series).
This story sheds a whole new light on the Green Lantern Theory of the Presidency, a popular myth discovered by Dartmouth professor Brendan Nyhan, as Ezra Klein reported it in Vox in 2014:
