Lady Lark (Linda Lewis), later named Skylark, is a character in the Marvel Comics series Squadron Supreme and hails from Earth-712. She first appeared in Avengers #85 (February 1971), and was created by Roy Thomas and John Buscema. She is based on Black Canary and later on Hawkgirl in DC Comics.

Linda Lewis was a singer before an enemy of the Squadron Supreme, Doctor Decibel, surgically implanted synthetic vocal cords into her throat, giving her the ability to generate a "sonic cry" which could incapacitate opponents. A reluctant hero at best, Linda often wished to return to her singing career.

She often partnered in crime-fighting, and later romantically, with the character Golden Archer (mirroring the relationship between the modern Black Canary and Green Arrow); however, she refused his marriage proposal. The Archer then used a mind-altering device to literally change her mind, but this had the unintended side effect of altering her personality to an air-headed, vapid persona that put her feelings for the Archer above all other priorities. This led to the two of them leaving the Squadron Supreme for a time.

When the Archer died under his later identity of the Black Archer, Lady Lark seemed to slowly shake off the effects of the mental modification, and returned to active status with the Squadron. Feeling she needed to increase her abilities to stand beside teammates that she perceived as more powerful, she began using the artificial wings that once belonged to deceased teammate Blue Eagle to gain the power of flight, and renamed herself Skylark. With this new ability came greater confidence, and Skylark became far more aggressive in combat than she had been as Lady Lark.

When returning to her native dimension with the team, she is injured and remanded to hospital care.

An alternate version of Lady Lark appears in the Supreme Power: Hyperion mini-series.

For this reason, she decided to gather every monster in order to keep them safe.^[1] She arrived on Earth in order to capture Fin Fang Foom and had her minions capture the monster, but they were defeated by She-Hulk, Miles Morales and Amadeus Cho. Lady Hellbender then clarified her motives, ending the fight and she offered to take the monsters that Amadeus had captured.^[2] However, when Amadeus defeated Fin Fang Foom, Lady Hellbender decided to capture him, since she fought that Amadeus was the strongest monster on Earth.^[3] Amadeus' allies tried to save him, but Lady Hellbender released all of the monsters she had on her ship, as she prepared to leave Earth. Amadeus freed himself and defeated the monsters and then Lady Hellbender accepted Amadeus' objecton to come with her and left.^[4]

He broke into their base and snapped Mister Immortal's neck, though clearly he did not die, and killed Squirrel Girl's companion Monkey Joe. However, he was immediately stopped by Big Bertha who had just returned from a modeling session, and was defeated by being sat on by her. The rest of the team returned home and interrogated him where he revealed that Doctor Doom had battled the Fantastic Four in Greenwich Village hence why he was wearing a Doom inspired costume, it had been "all the rage" in his area.

Llyron is the son of Llyra, and was genetically accelerated in age by Llyra so that he might take the crown of Atlantis. His mother Llyra was a Lemurian/human hybrid and a foe of Namor. She decided to conceive a child with Namor and introduce him as a successor to the Atlantean throne. After discovering that Namor was sterile, Llyra instead seduced a human named Leon McKenzie to create Llyron. Leon's father Lawrence was Namor's half-brother via their father Leonard, thus making Leon Namor's nephew and by extension Llyron is Namor's great nephew. The Atlantean Council voted Namor off the throne, and declared Llyron to be his rightful heir. However, the sorceress Morgan le Fay raised Atlantis from the ocean floor, and in the resulting chaos Llyron left with a number of Atlantean refugees to find a new home.

Llyron is named after his maternal grandfather Llyron who was Lemurian. His maternal grandmother was a human named Rhonda Morris.

He has resurfaced in the Thunderbolts series, as the leader of Fathom Five, a militant Atlantean splinter group determined to destroy humanity.

Luis is a fictional character who originated in the Marvel Cinematic Universe before appearing in Marvel comics. The character, created by Edgar Wright, Joe Cornish, Adam McKay and Paul Rudd, first appeared in the 2015 film Ant-Man.

Introduced in the 2015 film Ant-Man where he was portrayed by Michael Peña, Luis is Scott Lang's best friend and former cell mate at San Quentin State Prison. Luis' reason for imprisonment was due to him stealing two smoothie machines, which he seems unusually proud of. Due to Scott's estrangement from the ex-wife, Luis lets Scott stay with him and his two friends Dave and Kurt (played by Tip "T.I." Harris and David Dastmalchian respectively). However, Luis' primary reason for doing so was so that Scott could help rob Hank Pym's house. With no other choice, Scott helps him leading into a series of events that starts Scott's eventual reformation and acceptance of the Ant-Man mantle. Later, Scott calls upon Luis and his friends into helping break into Cross Technologies. Luis goes disguised as a security guard and expresses uneasiness, yet excitement at being a "good guy" and then reaffirms this by rescuing a guard he had earlier knocked out. He, along with Dave and Kurt, attempt to aid in Scott's final battle with Darren Cross, but are scared away by the abundance of police officers in the area. At the end of the film, Luis informs Scott that he heard that the Falcon was looking for Scott.

In the 2018 sequel Ant-Man and the Wasp where Peña reprised his role, Luis founds X-Con Security Consultants along with Scott, Kurt and Dave. Luis conducts business despite Scott being placed under house arrest (due to the events of the 2016 film Captain America: Civil War), and occasionally takes part in playing with Cassie Lang. When Scott arrives with Hope van Dyne and Hank, Luis happily chooses to work with the three in capturing Ava Starr. Later on, however, Luis, Kurt and Dave are captured by Sonny Burch who injects Luis with truth serum to make him reveal where Scott and Hank are. Through effort, Luis gives up Scott and Hank's location to Burch and Ava. Luis, Kurt and Dave take part in the chase through San Francisco, knocking out Burch and using the truth serum for revenge. After Scott is released from house arrest, Luis works alongside his friend and their company is hired for a new business.

Luis made his comic book debut in The Astonishing Ant-Man #1 (December 2015), by Nick Spencer and Ramon Rosanas. He is once again Scott Lang's cell mate, but does not have any speaking lines. He does seem to sympathize with Scott, as he looked helpless watching Scott getting beaten up by other inmates.^[74]

Luis appears in Lego Marvel's Avengers, voiced by Michael Peña.^[75] He narrates the "Ant-Man" DLC.
