'''[[color:red:The Good Guys]]'''

!!Akira Kogane
-->'''Voiced by:''' Creator/KazuhikoInoue

The leader (known to his teammates as "Chief") of a small group of astronauts hailing from the planet earth, when his crew returned from a long journey only to discover that their home world was ruined by a nuclear war, they were abducted by a slave ship from the evil planet Galra, which is found in the great dark nebula. However, Akira and his four comrades escaped from Daibazaal's prison facilities on Galra. After being ambushed by a swarm of Galran attack ships, Akira was forced to land on the planet Altea, it was there that he and his friends were chosen to resurrect the the legendary mechanical space guardian, Go Lion. At first there were only four keys to be found, and Akira had to Pilot the Green Lion... but when the fifth key was recovered, Akira gave his lion to Shorty, and took control of the great Black Lion.

* [[RedOniBlueOni Blue Oni]]: To Isamu's Red Oni.
* TheHero
* RedIsHeroic

!!Takashi Shirogane
-->'''Voiced by:''' RyuseiNakao

Akira's second in command, nicknamed "Quiet" because he rarely spoke. Takashi served his teammates as commander of the Blue Lion, that is until his untimely death at the hands of one of Galra's Beastmen.

* TheLancer: in the original group (see entry).
----
!!Isamu Kurogane
-->'''Voiced by:''' Creator/YuuMizushima

The dumbass, cocky member of the party of escaped earthlings. For some reason, he earned the nickname "Moody". Apparently, he has plenty of enthusiasm to operate the Red Lion. While he may not be the best fighter in the group, battling Galra would be dull without him.

* TheHeart: Before Takashi's death.
* TheLancer: After Takashi's death.
* {{Red Oni|Blue Oni}}: To Aklira's Blue Oni.
----
!!Tsuyoshi Seido
-->'''Voiced by:''' Creator/TesshoGenda

The largest and ugliest of the five explorers, his short temper has given him the nickname "Hot Head". Tsuyoshi had plenty of guts to pilot the Yellow Lion, but his weakness might be his phobia of heights (he somehow displayed that when his party was escaping their cell). While he takes great pride in battling for Altea, his biggest regret was leaving his younger sister in their war-torn homeworld.

* TheBigGuy
* HotBlooded
----
!!Hiroshi Suzuishi
-->'''Voiced by:''' Creator/MasakoNozawa

The youngest of the five astronauts, Hiroshi, a.k.a. Shorty, has served as the quickest, and most elusive fighter of the bunch. As Sadak had sent a fleet of galran war machines to recover the escaped prisoners, Shorty managed to scout the area, leaving the other four to command the lions. But when the missing key to the Black lion was finally found, Akira gave the green lion to Shorty, and the five earth heroes were able to forge the creatures to become Golion.

* {{Ninja}}: He is a descendant of those people.
* ShorterMeansSmarter: It's basically TheSmartGuy as a KidAppealCharacter.

!!Princess Fala
-->'''Voiced by:''' Rumiko Ukai

Heiress to the throne of Altea, and lone surviver of the royal family. Fifteen years ago, Daibazaal and his henchmen Honerva and Sadak, attacked Castle Altea, killing everyone in the palace. . . . . save two, as the newborn Fala was taken into hiding by her father's general, Raible. And now on her sixteenth birthday, Fala had welcomed the five heroes from earth with open arms. When Takashi was killed by Honerva, and her ferocious Beastman, it was Fala who later took the opportunity operate the Blue Lion (even if it meant disobeying her elder's orders), thus becoming the team's new Chick, leaving Isamu, of the Red Lion to take over as Lancer.

* PrincessesPreferPink: Her outfits in this series as pink more often than not.
* RoyalsWhoActuallyDoSomething: After Shirogane died, she promptly decided to become Blue Lion's new pilot. Arguably justified, because she knew that without five pilots, they couldn't form Golion, and there was no telling how long it would take to find someone else to be Blue Lion's pilot.
* SimpleYetOpulent: Her princess dress has just a few frills.
* SpoiledSweet

!!Raible
