Question

Does Marvel have an equivalent of the Green Lantern?

I know there's "Nova", but I mean is there a superhero or villain in Marvel that has the same powers as — or "close to" that of — the Green Lantern?

For example:

• a ring

• some kind of powers that look like a light show

• can make constructs similar to a Lantern Corp-er

Answer 1

Freedom Ring

Freedom Ring (real name Curtis Doyle) is a fictional superhero appearing in American comic books published by Marvel Comics. The character was created by writer Robert Kirkman. Curtis first appeared in Marvel Team-Up vol. 3 #20 (July 2006), becoming Freedom Ring in the next issue. He appeared across the series' storyline "Freedom Ring" for five issues. The character is depicted as a normal civilian who comes across a ring that grants him the ability to alter reality.

[...]

Curtis Doyle originally had no inherent super-powers on his own. However, the character comes into possession of a ring crafted from a fragment of a destroyed Cosmic Cube which allows the wearer to alter reality within a radius of roughly 15 feet (4.6m) around him, giving him a 30-foot (9.1 m) sphere of reality he can alter.

After his first attempt as Freedom Ring, he altered his physiology to give himself superhuman strength, speed, stamina and durability.

The Cosmic Ring gives Curtis Doyle the powers of flight, super-strength, increased durability, the ability to generate objects, and a way to overcome the paralysis of his legs. Generated objects first manifest in a shimmer of light and then take on a normal appearance:

Answer 2

The first Marvel pendant to Green lantern was Doctor Spectrum.

Doctor Spectrum was originally introduced in 1969 a member of the Squadron Sinister, an evil pastiche of Justice League, where he was the stand-in for Green Lantern. Later, in 1971, Marvel invented a parallel Earth reminescent of the DC Universe, with a good version of the Squadron, now called Squadron Supreme, in the role of the Justice League (and a good Doctor Spectrum filling in for GT).

Later still, in 2004, the Squadron Supreme was rebooted with J. Michael Straczynski at the helm in the title Supreme Power and spin-offs, featuring yet another version of Doctor Spectrum.

There was also a female version at one point, introduced in 2005 in The Thunderbolts.

All versions of Doctor Spectrum derive their abilities from an alien gem called the Power Prism, worn on the back of the hand. It bestows on a host the ability to project and manipulate light energy in various colors; create light energy constructs of various shapes, sizes and colors; flight; protection from the rigors of space and the ability to become intangible. The Power Prism is vulnerable to ultra-violet light.

Answer 3

A few characters named Quasar wear the Quantum Bands, a piece of superscience jewelry that lets one create light constructs through its control of electro-magnetic radiation, although said constructs can be completely invisible. These bands have been gifted by Eon to multiple heroes. The manifestation of these light constructs often seems to consist of invisible armor across their bodies or spheres of light around their hands with which they pummel opponents. They can construct more complex items, but they can also blast the same energy out, removing the need to create a more complex construct.

Ms. Marvel (MCU)

The Marvel Cinematic Universe's iteration of Ms. Marvel has powers remarkably similar to the Green Lantern's iconic ring constructs. She even refers to her abilities as "hard light" constructs (emphasis mine):

Kamala Khan accessorizes her Captain Marvel outfit with an antique bangle sent by her grandmother from Pakistan. […] The bangle activates hidden powers in Kamala, however, allowing her to create blasts of solid crystalline energy that she calls "hard light."

^{(Images above are from Marvel Studios’ The Marvel Cinematic Universe: An Official Timeline)}

While she doesn't have an iconic ring like the Green Lanterns, Kamala's bangle (actually a Quantum Band) acted as the catalyst to unlock her latent ability to generate constructs made of solidified light energy.

Just like a Green Lantern, she can manipulate this "hard light" into various shapes and forms, though mostly simple ones for now. She's not quite at the level of creating the intricate, complex shapes we've seen the Lanterns form. One thing she can do, though, is shape her "hard light" into a fist, similar to what some Green Lanterns do.

There are also a few key differences between Ms. Marvel and the Green Lanterns. For one, she can't fly or soar through the skies like her emerald-clad counterparts (at least not yet). And she doesn't have an equivalent to the iconic "In brightest day..." oath that Green Lanterns recite. But who knows, maybe she'll come up with her own cool catchphrase in the future!
