In 2026, as the Astral Express rolled through ever more dangerous corners of Honkai Star Rail, a veteran Trailblazer opened an old survival log. The sustain role had grown crowded, but the early units that once kept teams alive through the Simulated Universe and Forgotten Hall still shaped how players understood protection, healing, and taunt control.

The journey began with the free characters every account could claim, then climbed toward limited five-stars whose kits turned fragile squads into immovable walls.

8. Fire Trailblazer

The story unlocked the Fire Trailblazer for every player, a Preservation unit who taunted enemies and accumulated Magma Will with each incoming blow. Once four stacks lit up, the basic attack became an area-of-effect strike. It was a reliable, no-pull solution. The shields were modest, but the free Eidolons made the Trailblazer a respectable early tank for those who saved their Stellar Jade.

7. Natasha

Natasha ran an orphanage in the Underworld and carried that caretaker instinct into battle. As a four-star Abundance character, her skill healed and cleansed a single target, while her ultimate restored the whole team. For many early Trailblazers, she was the only healer available. But as later sustain units arrived, her output and utility began to feel limited, especially in high-pressure endgame stages.

6. March 7th

March 7th was the cheerful face of the Astral Express, but her shield was no joke. She placed a strong barrier on one ally, cleansed that ally, and increased their chance to be targeted if their HP remained high. When an enemy hit that shielded character, March fired back with a counterattack. Her ultimate spread Ice damage and could freeze enemies, making her a surprisingly aggressive Preservation pick.

5. Bailu

Bailu belonged to the Vidyadhara race and practiced medicine with a quiet confidence. Her ultimate placed the Invigoration status on teammates, which healed them when they took damage, twice per application. Her skill bounced healing to additional allies, and she could revive a downed teammate once per battle. That revival saved countless runs. Unfortunately, her lack of a cleanse became a serious weakness in late-game fights stacked with debuffs.

4. Lynx

Lynx arrived later and immediately became a favorite for specific teams. Her skill healed a target and increased their Max HP for the duration. If that ally followed Destruction or Preservation, Lynx also raised their aggro. Blade, Clara, and Gepard loved that extra attention. Her ultimate provided an area-of-effect cleanse, a utility that Bailu lacked and that late-game battles demanded.

3. Gepard

The dependable Captain of the Silvermane Guards turned defense into a win condition. Gepard's ultimate generated an enormous shield for the entire team, scaling directly off his own Defense. That made him easy to build; offensive stats were unnecessary. His skill could freeze a single enemy, though smart players conserved skill points and relied on basic attacks. He also drew more enemy fire and could revive himself once per battle.

2. Luocha

Luocha carried a coffin and a calm smile, but his kit was pure aggression. By accumulating Abyss Flower stacks, he deployed a field that healed any ally who attacked an enemy. That passive healing let the entire team stay offensive. His skill healed a single target and triggered an automatic out-of-turn heal if an ally dropped below half health. His ultimate dealt area damage and stripped one buff from all enemies, making him the premier healer of his era.

1. Fu Xuan

Fu Xuan sat at the top of the old sustain charts for a reason. Her Matrix of Prescience reduced incoming damage and transferred much of it to her. She also raised allies' Max HP and Crit Rate, blending survival with offense. When her own health dropped low, her talent healed her back, and her ultimate refreshed that self-heal while restoring a small amount for the team. If other healers feared instant-kill attacks, Fu Xuan could simply absorb them.

Looking back from 2026, these eight characters were more than a tier list. They taught the Trailblazer how to balance shields, healing, cleansing, and aggro management. New sustain options would arrive, but the lessons these classic units left behind remained timeless.
