Arknights: Endfield | Will Rossi be a Heat Operator? Player: She might be a Heat Vanguard!

RavenRavenFebruary 27, 2026

Little Red Riding Hood Rossi is about to debut. Of course, she could also be a reinforcement for the Heat team or the main Physical DPS for the Physical team! (Speculation based on training records)

I checked the concept art; it's Little Red Riding Hood from the player's storyline—

White-haired, red-eyed, equipped with a device resembling a thermal sensor, with a slightly tsundere expression and a rather confident stance.

From the main storyline and character illustrations, it is evident that Rossi is the younger sister of Wulfgard and also a little wolf. In her various actions, Little Rossi exhibits very canine-like behavior—she licks the back of her hand, sniffs, wags her tail, and holds great admiration for the Endministrator. Through her, we hear many wondrous legends about the Endministrator.

But that’s not the focus today. The focus is—What exactly is Rossi's element?

Among the characters currently released in Endfield, their elements are mostly revealed. Perlica is electrical, and Chen Qianyu is physical.

Only Rossi is tightly kept under wraps by the official sources.

But this only fueled the Endministrators' desire to investigate.


Someone inferred from her equipment: Heat

Look at the device on her back; doesn't it resemble a radiator? Her color scheme is mainly red and black, and her gaze carries a "don't mess with me" vibe. With this setup, she'd be Dehya in Genshin Impact, and Surtr in Arknights.


The three essential elements of the heat element: red, scorching, and temperamental.


Rossi took two.

Some people also guessed her class: Vanguard

Why is it a Vanguard?

Due to the current team composition of the Endfield Heat squad, there is a need for a operator who can rush in at the start, deal damage, and hold the field. Perlica is a crowd control type, Chen Qianyu specializes in single-target damage, and Gilberta leans towards functional support; none of them seem to be the best teammates for the Heat element.

Who is charging ahead?

Currently, we are using our 4-star Akekuri. If Rossi replaces Akekuri, she can be on the same team as her brother, Wulfgard. According to insider information, when Rossi triggers a combo skill, Wulfgard will have a special voice line.

At this point, if there were a operator who could "apply heat infliction and charge head-on, generate SP on their own, and finish the fight quickly," the entire team's flow would feel much smoother.

Rossi's temperament is perfectly suited for this role.

Bold speculation arises: Rossi = Heat Vanguard

As soon as this statement came out, the comment section exploded—

Heat Vanguard? Isn't that the Siege from Arknights?

"Siege Alter, a dignified serialization."

"Don't end up being a Heat Defender who uses skills to barbecue yourself."

"It could also be a Support role, with a skill that applies heat infliction?"

However, some have seriously analyzed that the current combat pace in Endfield is relatively slow, and there is indeed a need for a character who can quickly get started. A Heat Vanguard who can both deal damage and recover SP, while also applying the heat infliction, perfectly fits map exploration and high-pressure openings.

And look at Rossi's stance—left foot stepping forward half a step, center of gravity lowered, hands resting at her waist—it's a posture ready to charge at any moment.

Not a Vanguard, could it be a Defender support?

Of course, there are also the calm skeptics who pour cold water on it:

"Don't talk nonsense, what if it's a support?"

"Could also be a Vanguard, specialized in burning bushes."

"The scariest thing is—the four-star given for check-in."

There is an outcry of wails beneath this comment.

To be honest, I'm scared too.

But from another perspective, even if it's a four-star, as long as it feels good to play and the character design is solid, you should still invest in them. Players of Arknights know well how many four-star war gods there are.

Moreover, Endfield currently has a solid character foundation. Characters like Rossi, who have a "cold but serious" demeanor, are very likely to become the next wave of fan favorites, as long as the subsequent storyline remains consistent.


Is Rossi a Heat Vanguard?

Unknown.

But she has already ignited a fire in the hearts of players.

When the day comes online, whether she is a Vanguard or a Defender, draw if you should.

After all—white hair and red eyes, who could resist? (Besides, what if it's a six-star?)
