Then I apologise for not elaborating further.
Most demons you encounter in Doom Have been Stated to use Hell energy. A large majority of the Doom 2016 codex have outright stated that even Fodder troops Like the Imp use hell energy. Hell energy is something demons or creatures from hell have access to
During the Age of the ancestral Titans the codex makes it Clear that there were tribes of Sentinels battling against the Ancestrals. While an exact number is not given, It's obvious that there were multiple sentinels standing up against the ancestrals during these battles.
"clergy and reinforcements, the Sentinels proved their worth in what would be their final war with the forces of all evil. Unrelenting power in the face of certain death, the Sentinels crushed hundreds of demons and skewered Titans. When their Atlans held no more fuel the Sentinels took to the ground and fought the swarms on land. All of Hell knew of the Betrayal, for it was without question the Maykrs and the Priests who had sowed the seeds of deceit long before the brave warriors passed through the gate. What Hell saw that day was the beating heart of the free people of Argent D'Nur; they did not flinch in the face of their own certain death. They died as they lived, with sword and shield in hand, Urdak too low a place to house such giants. Theirs would be the fate of warrior gods, remembered for all time."
This exact codex here outright stated that the Atlans would run out of power first, rather then be destroyed in combat and that they were used to slaughter multiple titans. Either Atlans were used to Kill multiple titans or when they ran out of energy, The Sentinels Fought Titans without there Atlans. So no matter how you look at it, It's pretty clear that a single Atlan can slaughter more them one Titan. That or Sentinels without Atlans can Slaughter Hell Titans, Once again proving that Altans are not needed, There just more practical and efficient at killing titans.
