If Bond Coordination Battle represents the bond between a Trainer and their Pet, then Legion Warfare represents the collective power of Trainers.
Through Legion Warfare, Trainers can gain the power boost of all the Trainers in the legion, and use this boost to maximize the strength of their Pet, allowing the Pet to display a brand new posture capable of sweeping through a thousand troops.
Logically speaking, Bond Coordination Battle and Legion Warfare cannot be used simultaneously.
However, in the Star Calendar Epoch, the legendary Marshal Stuart Lionheart had once assembled the power of a million Trainers with his legendary body to engage in Beast Legion combat and contend with an Immortal from beyond the domain.
But even if a million Beast Legions fought, a Legendary Strong One couldn't face an Immortal head-on. When Marshal Lionheart was on the verge of defeat, the ultimate bond between Trainer and Pet allowed him to break the limit.
