In Jain cosmology, each half-cycle (avasarpini) has exactly 24 Tirthankaras in a fixed order. In the current half-cycle we are following that sequence, and Mahavira is the 24th Tirthankara. When this half-cycle ends, the next half-cycle will begin again with Rishabhanatha as the first Tirthankara, followed by the same sequence of 24 Tirthankaras.

So, the coming cycle will start with Rishabhanatha, and then proceed in the same traditional order as the present cycle, ending with Mahavira before the cycle turns again. This is the standard Jain view across both Digambar and Śvetāmbara traditions. If you’d like, I can list the full 24 names in order.
