Between 1994 and 2007 the Legion of Super-Heroes went through several changes. After several decades of adventures, the original LSH was rebooted during the Zero Hour event. It happened again in 2004 with the Threeboot version of the futuristic team by Mark Waid and Barry Kitson.

In 2007, Geoff Johns and artist Gary Frank resurrected the original team introduced in 1958's Adventure Comics #247. Now officially in their mid-20s, their costumes were changed to reflect 31st-century fashions. Many of the adjustments were good news for Legion members that mixed these new styles with nostalgic touches.

10 Tyroc Received A Nice Upgrade

Tyroc received a good costume update for is reappearance.

Created by writer Cary Bates and artist Mike Grell, the Legionnaire named Tyroc was one of DC's first black superheroes. He actually predated Black Lightning by one year. His original costume took the cue from the remakes illustrator Dave Cockrum made to many Legion outfits during his tenure with the team. It was primarily a one-piece leotard with a high collar and laced-up v-neck.

When he returned in the sixth volume of Legion of Superheroes (2010), Tyroc was given a more flexible costume. A red one-piece with white elements and three circles -- one on the chest and two on the shoulders. These were a call-back to the hero's former costume.

9 Ultra Boy's Costume Is A Mix Of Previous Incarnations

Jo Nah's costume was a mix of recent incarnations.

Ultra Boy's original costume was a bit plain. A simple red tunic and green pants, its defining piece were his boots with the fancy red trim at calf-level. However, these were rarely seen.

Artist Gary Frank gave Jo Nah a bit of flash when he reintroduced the adult version of this Legionnaire in Superman and the Legion of Super-Heroes. It incorporated elements of the group's last two incarnations. In particular, the sleeveless look Ultra Boy had in the Threeboot version of the team. The gloves are a good touch as they protect his hands in case he doesn't switch from ultra-strength to ultra-invulnerability fast enough.

8 Brainiac 5 Expanded On His Classic Look

Brainy touched up his classic look.

Querl Dox's Legion costume isn't really one. it's a purple jumpsuit, something originally worn by the citizens of Colu when he became a Legionnaire. The only noticeable element is a yellow belt that contained his force field generator.

The adult version of Brainiac 5 has a similar look. However, it's also a statement against the clothing decisions of others on Colu. Those are standard unitards instead of Brainy's padded turtleneck and high-collar jacket. He isn't the only Legionnaire to call back to simpler times. Shadow Lass and Duplicate Damsel (formerly Duo Damsel) also went back to long-standing outfits in their adult incarnation.

7 Sensor Girl Mixed Old And New In Her Costume

Sensor Girl's new costume mixes old and new.

In the 1980s, Legionnaire Princess Projectra initially retired from the team after her husband Val Armorr, the team's Karate Kid, was killed. However, she returned a few months later as the masked hero Sensor Girl. Only Saturn Girl knew who she was. The other Legionnaires didn't realize it was their former colleague in the red-and-white caped costume until much later.

Returning to the Legion in the sixth volume of the series, the hero mixes old and new. Minus leggings and featuring an open space in the center of her tunic, Sensor Girl's adult costume isn't as conservative as the one she wore in the 2980s. Though initially shy, this costume now represents the hero's openness.

6 Saturn Girl Maintains A Classic Look

Saturn Girl's costume has a classic look.

Except for the 1970s "bathing suit" and her new 31st-century look in the post-Doomsday Clock world, Saturn Girl's costume hasn't differed much since the 1960s. The red-and-white pattern with a chest-high emblem of the ringed planet is a classic design. It barely changed during the Zero Hour and Threeboot versions of the character.

If anything, the costume designed by Gary Frank is more form-fitting than previous designs. Additionally, her shoulders are all white instead of a mix of tones. It's a fine fit for a hero who is one of the Legion's founding members.

5 Mon-El Has A Green Lantern Thing Going

Mon-El was briefly a Green Lantern

Mon-El got a power boost during the sixth volume of Legion of Super-Heroes. Sodom Yat, the last surviving member of the Green Lantern Corps, passed his ring to the villain-turned-Legionnaire Earth Man. When he decided it was too much responsibility for him the ring went to the already powerful Mon-El.

As a result, the Legionnaire received a cool costume change. Instead of the normal green-and-black combination of other Lanterns, Mon-El's outfit was all black. Green elements, including the lantern symbol, ran down the center of his one-piece costume. A green cape complemented the ensemble.

4 Dawnstar's Costume Represented Her Growing Legion Prominence

Dawnstar's costume represented her more mature status.

Though Dawnstar disappeared from the second and third incarnations of the Legion she literally returned with a bang in Superman and the Legion of Super-Heroes. In fact, she was one of the first Legionnaires the Man of Steel met when he landed in Geoff Johns' version of the 31st century.

This winged hero was revealed as more than the Legion's tracker. Her natural leadership tendencies emerged during the team's latest crisis. Thus, her costume reflects this with a similar design to her original with brown highlights.

3 Cosmic Boy's Costume Reflects Many Ages

From his first appearance in Adventure Comics, Cosmic Boy's costume was pink and black. It suited him well. He returned to it after Dave Cockrum's 1970s redesign which was simply a tube top.

For unknown reasons, the artists of the second and third Legion incarnations put Cos in a blue-and-black outfit. While it was fine, it didn't have the oomph of his original. Gary Frank probably understood this when he created the hero's new costume. It had elements of all of Cosmic Boy's iterations. However, it's the person inside the outfit that matters.

2 Lightning Lad's Costume Emulates His Bad Boy Attitude

Garth Ranzz wasn't known as the Legion's bad boy during its initial run. Sure, he had a bit of an attitude, but he was pretty straight-laced. This is particularly true when he became a house-husband to his twin sons while his wife, Saturn Girl, returned to active Legion duty.

Yet, in later Legion incarnations, Lightning Lad is revealed as one of the Legion's rebels. When Geoff Johns and Gary Frank reintroduce Garth he came with that attitude. His costume, while similar to a design created in the 1970s that lasted for decades, stripped away his sleeves. In turn, viewers were able to see the hero's Legion tattoo.

1 Wildfire's New Costume Is Similar To His Zero Hour Counterpart

Wildfire's initial costume, created by Dave Cockrum in the 1970s, never made sense. The hero is composed of anti-energy, yet his outfit seemed to be made of basic 30th-century fibers. One rip and he was released into the air as a mass of power.

His new costume, introduced in Superboy and the Legion of Super-Heroes makes more sense and is one of the coolest updates of the adult Legion. With elements taken from the second incarnation of the character, Wildfire's costume is more of an armor. What's great is it reveals to the reader how much energy flows through his essence to create power beams.
