Sirius & Orion was holding back in trailer and quest and definitely are strongest warframe in lore right now

In the Jade Shadows Constellations trailer, Sirius and Orion battle on Venus, standing on top of a dead Third Mother Orb, which had already been destroyed by their battle. Their battle leaves Venus devastated in destruction, with the surrounding environment being heavily destroyed by their clashes. As the fight continues, they fly and fight from Venus to Uranus in a matter of seconds they did this with no arching spaceship or railjack, continuing their battle along the way. Their final clash culminates in a massive Void-paradox explosion, which they tank point-blank with zero damage taken. This shockwave of the explosion was powerful enough to awaken Hunhow, they did this all with only celestial clash alone neither Sirius nor Orion uses any of their other abilities during there battle.

In the quest hunhow warns stalker of there battle and tell his there battle will rage on for eternity unless he stops them 

Their abilities extend beyond raw destructive power and are explicitly characterized by their cosmic nature. Hunhow describes time as a river and states that Sirius and Orion have “learned how to swim upstream,” referring to their ability to navigate through time using the Void. They travel approximately 20 years from a future timeline into the present timeline through the Void specifically to find the Stalker, demonstrating that their mastery of the Void allows them to overcome conventional temporal progression and traverse different points in time. Their cosmic abilities are further demonstrated through Celestial Clash, which manifests as a cosmic duel between two alternate versions of the same existence.

Celestial Clash itself is a manifestation of their cosmic conflict—a literal cosmic duel between two alternate versions of the same existence. Sirius and Orion violently collide, unleashing enormous shockwaves of cosmic energy and cosmic destruction as their attacks meet with meteoric force. Their opposing timelines and intertwined destinies converge during these collisions, producing colossal collateral damage, reality-distorting explosions, and increasingly destructive Void-paradox phenomena. Their clashes are capable of tearing apart the fabric of reality itself. The underlying reason is that Sirius and Orion aren’t simply two unrelated beings fighting in the same location they are incompatible versions of the same person originating from divergent timelines. Through their connection to the Void and Eternalism, these normally separate possibilities are brought into direct interaction. Their physical collision forces two mutually divergent versions of the same existence to occupy and violently interact within the same space, creating a paradoxical phenomenon that can destabilize the boundaries between their divergent realities. This makes Celestial Clash fundamentally different from a conventional physical attack. Its effects aren’t restricted to damaging matter or the surrounding environment—they extend into the structure of reality and the relationship between divergent timelines. Their conflict is explicitly centered around fighting to erase the other and secure their own future, making their confrontation directly connected to the survival of their respective timelines. If they were allowed to continue fighting unchecked, they would ultimately erase one another and their respective timelines. Celestial Clash is therefore far more than a conventional Warframe ability. It is a cosmic duel between two incompatible versions of the same being, producing immense cosmic destruction, reality-tearing collisions, Void-paradox phenomena, and potentially timeline-level consequences.

Sirius & Orion possess an extraordinarily diverse arsenal Coronal Ejection wields a Jade Light-infused scythe, Jade Stars crown them with seven celestial stars that launches and tracks enemies whenever they attack ,Light’s Sanctuary summons a well of light capable of healing, regenerating, and resurrecting allies, Gravitic Slash inflicts Slash damage while reducing enemy defenses, Astral Shell can nullify and negate incoming damage while creating an explosive decoy, and Event Horizon summons a black hole that deals Heat damage. Their abilities can also be shared, stacked, and synchronized with one another because Sirius and Orion are different-timeline versions of the same individual, allowing their powers to interact in ways that conventional Warframes cannot.

Sirius & Orion bypass several of the conventional limitations associated with traditional Warframes because they are fundamentally different from the Operator-dependent Warframe model. They are fully sapient, self-aware beings capable of thinking, fighting, and wielding their abilities completely independently without requiring a Tenno Operator to control them. As the first known full-blooded purebred Warframes and second-generation Warframes born from two existing Warframes, Jade and Stalker, their biology and origin are fundamentally different from the traditional human-derived Warframe lineage. Unlike conventional Warframes that originated from humans who were transformed through the Warframe creation process, Sirius and Orion were born as Warframes themselves. Consequently, they lack the traumatic human identities, human vulnerabilities, and psychological burdens associated with many conventional Warframes, removing limitations that could otherwise hold them back. Their unique development also gave them a direct connection to their parents’ powers. During her pregnancy, Jade devoted her energy and focus toward protecting and nourishing her unborn children, with her Jade Light surrounding and sustaining them. This provides a strong basis for Sirius and Orion inheriting aspects of Jade’s power, particularly Sirius’ direct connection to the Jade Light. They also inherit aspects of Stalker, whose unique Warframe lineage contributes to their anomalous nature. Their own power is inherent to their existence, with their abilities connected to Eternalism and the Void. They are considered demigods, not because they are literal gods, but because they represent an unprecedented evolutionary advancement of the Warframe lineage, possessing tremendous power, potential, and autonomy. Without a traumatic human identity or conventional human limitations holding them back, Sirius and Orion can operate at their maximum potential and fight at their full capacity while remaining completely autonomous from a Tenno Operator. Their unique birth, dual Warframe parentage, full sapience, anomalous existence, inherited powers, and unrestricted autonomy make Sirius and Orion fundamentally different from conventional Warframes and genuine anomalies within the Warframe lineage.

the Jade Light is a legendary Orokin execution weapon an absolute and powerful disintegration beam designed to completely disintegrate and vaporize its targets at the molecular level, leaving behind nothing but mist, gore, and hot dust. Its destructive nature makes it one of the Orokin’s most lethal execution methods, capable of reducing its targets to virtually nothing through molecular level disintegration.
