Summary
- Honkai: Star Rail features a variety of playable characters with unique abilities, strengths, and personalities.
- Having a diverse lineup of characters with different elements is essential for battling enemies with varying weaknesses.
- Even within the same path and element, characters have different skills and provide different benefits.
Honkai: Star Rail features dozens of characters that are currently playable, each with a unique personality and strengths, and there are more characters officially set to be added moving forward, continuously expanding the list. Unlike Genshin Impact, Honkai: Star Rail doesn't give exact information about its characters like height and birthday, but it's possible to estimate height and age, at least. As such, this listing is formed of guesses for height and age, but the elements and paths will be accurate to information given in-game.
Filling the role of the Trailblazer in Honkai: Star Rail, players the Astral Express on a fantasy space adventure from HoYoverse. Many companions that players encounter can be earned and added to their list of playable characters and teammates. Since enemy weaknesses vary, it's a good idea to have a variety of characters with different elements in order to be prepared to fight any enemy combinations that appear.

Honkai: Star Rail - Ruan Mei Character Builds (Light Cones, Relics, Team Comps)
Ruan Mei's Weakness Break buffs make her a top-tier unit in Honkai: Star Rail with plenty of strong options for Relics and Light Cones.
41 Argenti
Path: Erudition
Argenti is a character that follows the Path of the Beauty but, considering that does not exist in the gameplay mechanics, he embraces the Path of the Erudition. Argenti is a Physical DPS character in Honkai: Star Rail.
Argenti is fairly tall and should be at least around 6'1", though he may be slightly taller. He is a human, so his physical appearance sets him at around 30 and 35 years old.
40 Arlan
Path: Destruction
Arlan is a Lightning element Honkai: Star Rail character on the Destruction path. His age is likely in the late teens to early twenties. Thanks to some data compilation made based on official ads, posted by PromiseMeStars on Reddit, it is possible to determine that Arlan stands at roughly 5'1" tall.
While he can become an Astral Express visitor, he's otherwise found at Herta's Space Station.Arlan is the chief of security at the Space Station, which makes him a valuable asset to Herta and Asta. He has a pet dog called Peppy, which can be found roaming around the Space Station and can occasionally help in quests.
39 Asta
Path: Harmony
Another Honkai: Star Rail character found on Herta's Space Station, Asta is a Fire character on the Harmony path. Like Arlan, she's also in her early twenties, but probably no older than 23. As for height, she stands at an estimated 5'5" tall.
Asta is shown to be a caring character, and she has a lot of responsibilities on the Herta Space Station. However, she still keeps track of her colleagues and shows concern for Arlan during Companion Missions. This leads to the player being able to spend time with Arlan's dog, Peppy, in one of the best side quests in Honkai: Star Rail.
38 Bailu
Path: Abundance
Bailu is one of the few Honkai: Star Rail characters on the Path of the Abundance, making her a healer. When it comes to damage, her element is Lightning. Although her height of 3'9" and her usual demeanor make her seem younger, Bailu is in her late teens to early twenties, but likely not older than 21.
This is because Bailu is a Vidyadhara, a long-life species that tends to age more slowly when compared to regular humans. She is expected to live on to her hundreds, much like the other draconic denizens of the Xianzhou Luofu.
37 Blade
Path: Destruction
A former member of the High-Cloud Quintet in Honkai: Star Rail, Blade was previously known as Yingxing. He was a short-life species, but after a forbidden ritual made by Dan Feng, he was cursed with immortality due to his Mara affliction.

36 Bronya
Path: Harmony
Commander of the Silvermane Guard, Bronya is a Wind element character on the Path of the Harmony. She's likely between the ages of 23 and 25, and she stands at roughly 5'6" tall. The Delicate Snow Globe in Honkai: Star Rail reveals more about her past for curious players.

35 Clara
Path: Destruction
Among the younger Honkai: Star Rail characters, Clara is around 10 to 12 years old. For height, she stands at around 4'7" tall. Clara uses the Physical element and is on the Destruction path.
Clara is always accompanied by Svarog, a humanoid robot that leads all other robots in Belobog. His programming is to protect human life and, thus, protect Clara, the symbol of human purity.
34 Dan Heng
Path: Hunt
Dan Heng is one of the first Honkai: Star Rail characters to the player's team. He uses the Wind element and is on the Hunt path. He's also in his mid-twenties at around 23 to 25 years old, and he stands 5'7" tall.
Dan Heng is the reincarnated form of Dan Feng, a Vidyadhara who used to be the High Elder of the Xianzhou Luofu. He, however, committed a heinous crime and was submitted to the rebirth process, being reborn into two split people: Dan Heng and Bailu.
33 Dan Heng - Imbibitor Lunae
Path: Destruction
Dan Heng - Imbibitor Lunae is the awakened form of Dan Heng. In this special state in Honkai: Star Rail, Imbibitor Lunae draws on the power of the High Elder of the Xianzhou Luofu and uses draconic energy in battle, taking on the Path of the Destruction and embracing Imaginary as his element in battle.
Imbibitor Lunae keeps the same body as Dan Heng, but his newly exposed Vidyadhara horns should give him some extra height, boosting him to around 5'9" or 6'0".
32 Dr. Ratio
Path: Hunt
Dr. Ratio in Honkai: Star Rail is a character that follows the Path of the Hunt, which makes them a DPS unit. He uses Imaginary DMG in battle. He is a fairly enigmatic figure, so little is actually known about him so far.
However, based on his appearance, he should be around 35 years old. Dr. Ratio is a tall character and should match Blade's height, at around 6'2".
