Sam Lane

General Samuel "Sam" Lane is a ruthless military general of the U.S. Army, and the father of Lois and Lucy Lane. General Lane is a strong oppositor of all aliens, including Superman and Supergirl.

Early life
Sam Lane was born on the fifties into a military family. When he was a kid, his father used to bring he and his sister to the movies every Sunday, during one of this occasions they seen "The Day the Earth Stood Still", which strongly impressed and convinced him that aliens are the biggest threat to both the country and the whole planet, as their technology and their powers could wipe out the human race in a few moments.

Growing up, Lane follows the family tradition by joining the U.S. Army and climbing the hierarchy until he get the rank of general. Also he fathered two daughters: Daily Planet's reporter Lois Lane and military lawyer Lucy Lane, who also serves as a legal attaché on his staff. However, over the years, his relationship with Lois became estranged, due to his immorality and control issues over her life.

Due to his strong anti-alien ideas he view even Superman as a potential threat for the country and the world. Furthermore, Lane established a relationship of enmity with D.E.O., which considers inadequate to handle the alien threats.

Arriving in National City
General Sam Lane comes to National City, as he wants "Hank Henshaw" to transfer Supergirl to his unit, however, Hank cannot, as she does not technically work for the D.E.O., then he demand Supergirl to fight their field robot Red Tornado. Supergirl won the battle, breaking off the android's arm with her freezing breath, and causing damage in his system. As Red Tornado flew, Dr. Morrow said his robot activated the self emergency protocol so General Lane fired Morrow because he did not cope with the task. The next day, the general has dinner with Lucy and James, to whom he told that he is not worthy of his daughter—that he surrounds himself with special people because he's not good enough himself. Later, General Lane, Lucy and James are attacked by Red Tornado and Supergirl rescue them but is forced to allow the android to escape in order to diffuse a tornado it caused. Later, "Henshaw" suggested using alien technology that created the hologram of General Lane to draw Red Tornado and Supergirl destroy it.

Acting director of the D.E.O.
When "Hank Henshaw" was captured by Astra and Non's army, General Lane return to National City to temporarily perform his duties as director of the D.E.O.; he tortured Astra by injecting her with liquid kryptonite to know the location of their base, but she told them a false position, which turned out to be a trap. Then Supergirl decides to make an exchange of prisoners; despite the general was against it, he was forced to retreat as Kara stood his ground. After his return, "Henshaw" told General Lane that his presence in D.E.O. is no longer required, and he and his team leaves.

Myriad
When National City was put under the influence of Myriad, Supergirl contacted General Lane and asked him not to let anyone enter the city until she didn't understand what's happening. Later he calls her back saying that he had done his work and asks her to fulfill her.

Later, Lucy asks his father to release J'onn J'onzz (whose martian identity has been previously revealed making him a fugitive), but the general refuses to do so. However, he allows J'onn to go with Supergirl to fight with Non and Indigo. After their victory, General Lane said J'onn J'onzz that the President granted him a full pardon and re-instated him as the director of the D.E.O.; also he take Non's apocalypse device, the Omegahedron, under the military custody and later delivers it to Maxwell Lord.

Personality
Sam is extremely arrogant, short-sighted, rude, disrespectful, and ungrateful, even towards people who had saved his life, for no apparent reason, although he cares about the welfare of his country, he is quite selfish; as he always tries to blame other people for problems he has caused, as Sam is incapable of taking responsibility for his actions. He also wants what he arrogantly believes is best for his daughters. It can be assumed that he does not have a good relationship with his daughter Lois, due to the fact that he interferes in her relationship with men, which is none of his business to begin with, and mainly because of his immoral traits; as he has an anti-view on aliens in general.

Sam has a strong hatred for aliens, regardless whether or not they are a threat to the human race, he even dislikes anyone who associates themselves with aliens for no apparent reason, like James Olsen; due to the latter being friends with Superman.

Sam is also quite immoral, as he had Astra tortured with liquid Kryptonite, to try and get the location of where her comrades were keeping Hank Henshaw, he had no guilt or remorse for this vile act of his; this shows his hatred for aliens, which goes so far as to arrogantly believe they don't deserve civil rights.
