Exactly, as long as the MC is in the right spot at right time the loop continues without an end or beginning. And paradoxes are always a headache. This can also be applied to the past paradox Pokémon where one is brought to the present meets the MC gets pregnant but gets somehow sent to the distant past even further than when she originated and thus start the species and cause a loop like the future ones. A real headache.

The really crazy thing is that if Great Tusk, Scream Tail, Brute Bonnet, Flutter Mane and Sandy shocks are used in the paradox then the MC can consider there evolved decedents Ex: jigglypuff, Donphan, magnaton can then be considered his eventual descendants and show the paradox loop continues there species eventual creation.
