This study demonstrates the formation of distinct extreme outbreak dynamics in population models. We have investigated various intricate dynamics inclusive of the outbreak events in a single and two different coupling configurations. The system manifests abrupt deviations from the bounded region in an aperiodic interval owing to blowout bifurcation when the instability occurs in the invariant subspace. In addition, we have analyzed different transitions of the extreme outbreak dynamics using bifurcation plots and phase diagrams. The appearance of critical outbreak dynamics reveals a phenomenon known as dragon-kings, where the extreme values in the tail of the distribution depart from the expected pattern described by a power law. We performed comprehensive statistical measures of the dragon-kings test and cumulative probability distribution function to verify the emergence of dragon-kings dynamics in the system.
