Kyle Richmond was a thrill-seeking playboy who became the costumed adventurer Nighthawk. Starting out as a villain, Richmond soon found altruism a greater pursuit. As Nighthawk, he became a mainstay of the Defenders and has also acted alongside the Squadron Supreme, the Redeemers, the Thunderbolts, and the Initiative.
- Alternate Self: His most famous counterpart is the one from Earth-712, the reality of the Squadron Supreme. His other well-known counterpart is the black Kyle Richmond of Earth-31916, home of Supreme Power.
- Animal-Themed Superbeing: Animal alias variety. It's been noted that hawks aren't nocturnal.
- Badass Cape: His impressive red cape, which he can use as Cape Wings and glide.
- Badass Normal: Just like the character he's based on, he doesn't have any superpowers but is a well-known and valued member of the Defenders.
- Expy: Easily the most famous of Batman's Marvel's expies.
- Handicapped Badass: After a battle against the Six-Fingered Hand, he was paralyzed except at night when he regained his mobility. After an adventure in Hell, he got better.
- Heel–Face Turn: Started off as a rich brat who got his girlfriend crippled when he was driving drunk, then joined the Grandmaster's Squadron Sinister. Eventually becomes a Defender and member of various groups.
- Primary-Color Champion: His costume is mostly dark blue with a red cape and golden accents.
- Sucksessor: The Nighthawk of Earth-31916 thinks he's little more than Dumb Muscle and unimpressed with Kyle's mixed-bag adventuring history.
- Super Serum: Sure he can't shoot lasers out of his eyes, but he's definitely not all that human. He was given an alchemical serum when he was recruited to Squadron Sinister and these permanently gave him low-tier superhuman strength, toughness, and other attributes. And these abilities double in power at night.
- What Happened to the Mouse?: It is unknown what happened to him when it was exposed he had been replaced by a Skrull. It gets even more unclear when a new, black Kyle Richmond appeared as part of a new Squadron Supreme assembled by Phil Coulson and Mephisto.

The brilliant Russian neurosurgeon Dr. Tanya Belinsky would take first the mantle of the Red Guardian for some time. An encounter with a powerful villain made her the nuclear powerhouse Starlight.
- Atomic Superpower: Sergei Krylov exposed Tania to cobalt radiation and a nuclear explosion which resulted in her gaining the ability to generate, store, and release massive amounts of nuclear energy.
- Combat Medic: Red Guardian, who also was a skilled surgeon (she was the one who put Nighthawk's brain back to his body when it was stolen during a horrific surgery by the Headmen).
- Friendless Background: She never knew real friendship until she joined the ranks of the Defenders.
- Legacy Character: One of the many people that has taken the codename of Red Guardian.
- Radiation-Induced Superpowers: How she became Starlight.
- Red Is Heroic: Her costume is red and she's not antagonistic like the previous Red Guardians.
