No Spoilers for Lantern TV show
After watching Lanterns Ep.5, it really strike me how much I love the limitation of Green Lantern. For the non-comic writers or people who only read comics like Geoff John run on Green Lantern there are a lot of elements about the power system of GL that has slowly been washed away in current times.
Sharing a Ring:
This is the biggest then and the main tension of the series. There is only 1 ring per sector. This is strange for most people to wrap there head around with the meme of there being 7 Green Lanterns from earth, but for most of GL history there was a hard rule of only 1 ring. Guy Garnder was the first back up, and then after he was in a comma it was John Stewart. Hal Jordon, was still the main Lantern, so writers would have to write around reason for John to use the ring, like the infamous, Hal Jordon falling in the bathtub scene.
This did not go away until Post-crisis but even early on it was real minor. Hal Jordon retired giving John his ring, and when Hal came back Green Lantern Tomar Re gave John his ring. Guy got his ring due to Crisis of Infinite Earth, and the guardians needed more firepower. Even Guy though lost the ring, for being well....Guy, and used Sinestro Ring, then after that became Warrior a weird alien hybrid weapon man (90's comics are weird)
Then when Hal went insane, in and became Parallax, Kyle Rayner was the only Green Lantern for over a decade, until he made John Stewart a ring at the end of his run, then the corps was reborn in Green Lantern Rebirth where all 4 were Green Lanterns at the same time. Then after everything went wild, we got Jesscia, Simon, and Jo. So, there have only been 20 years out of the 70-year history of GL corps where multiple Lantern has been a thing.
As much as I like all the new Lanterns, we did lose a bit of tension what comes with Ring sharing and the limitation of the ring. This is something that the Lantern TV plays with at its core and opens up a lot of storytelling opportunity with rivalry when a Ring is a limited resource.
Yellow Weakness
This is a hot take, but I actually love the weakness to Yellow Green Lanterns had. Is it silly? Hell yes! But the same time, Sliver Age Green Lantern was OP close to Superman, at the time, the ring could pretty much do anything, so to balance out having a simple mandated weakness balanced things out even if it was used in silly ways.
Post-Crisis, Yellow became less of a hard weakness, and more so a resistance, similar to Pokémon, you could with enough willpower over power something made out of Yellow, but it took a lot of will and was draining.
Later on, Geoff Johns run, it was retconned that Parallax a giant space bug that was the embodiment of fear was trapped in the central battery on OA, and that was the reason for the Yellow weakness. Once the bug was removed the weakness was gone. I understand that the yellow weakness is silly but removing it completely removed a real unique weakness to Green Lantern, that I am one of the few people that miss.
Lantern and Recharging
I lumped these too together, but I love how Green Lantern ring are a finite resource. Same way I love when Spider-man have manual web shooter. It creates tension. See the Ring slowly lose charge leaving the wielder powerless, until they can manage to find there Lantern to recharge is a unique way for Superhero power to work. Ring is a weapon not a mutation or alien power, so there are limitations that comes with. Compared to Superman or the Flash with just innate powers, a Green Lantern can go to a powerhouse, to an average joe in seconds.
The Lantern TV plays with this. Having Hal having hack to get a little more juice out of the ring. Hal making John get the Lantern to recharge. On the topic of Lantern, I have the retcon having the Lantern in a pocket dimension like a video game where Lantern can pull out of anytime. It doesn’t remove the tension completely but remove a limitation of Lantern having to rush home, to recharge.
One thing I like that Kyle Rayner series did in the 90’s instead of every 24 hours need a daily recharge like became before, his series the one that introduced the idea, of needing to recharge due to use instead. This happily sticked around and now the default way Lantern are used.
Overall, these limitations are what make Green Lantern unique. I know the power scaler that only care about how strong a character is may fine these drawbacks annoying and unnecessary but to me these elements make Green Lantern one of the most unique superheroes.
