is Hal a planet buster? i mean currently im pretty sure he was in the Silver Age but how about now, can he destroy a planet with his energy beams?  also another curiosity, whats his strength level?  feats as proof would also work but please ive always wondered this...  and the same question goes for all the other earth GLs

hmmmmmm well im glad that i received this exhaustive explanation, there is no way that i could ask for more, oh no no no.  Infact i got bored reading all of that.   ;D

no hal cant bust a normal planet at normal levels with a energy blast from his ring

Plants are no match for the Green Lantern ring. Their photosynthesis cannot match willpower!

Depends on the writer. Geoff Johns, the current big cheese of GL universe, writes lanterns as significantly below planet destroying level. Other series have different takes. Rann-Thanagar War, for example, has Kyle and Kilowog casually altering the orbit of Thanagar with no apparent trouble.

He can destroy any plant, that is, unless it's yellow ;)

I'm sure Hal can kick any tree's ass but we know Alan Scott couldn't

Haha, we're such smart-asses, lol

There is one plant that might take him

I would like to believe that Geoff Johns isn't necessarily underselling the power of the Green Lanterns, but more likely saving up the big moments for when he feels they're right. Having Lanterns routinely cut planets in half doesn't make it awe-inspiring, but I feel as though when he DOES show something super powerful we'll all be thankful and amazed for the restraint he has shown. :)
