Pokemon Sun Moon Protagonis

So, lets look at Moon's accomplishments. She gained power to use plenty of Z-moves. She was choicen by Tapu, overcame series of trials, defeated four Kahunas, beat Elite Four and became the first champion.

She befriended a legendary pokemon and ride on its back into the ultra space.

She saved Alola and Ultra Megalopolis from Ultra Necrozma.

She saved the Either Foundation from invasion of the most dangerous bosses at their best (each won in their world and caught a legendary pokemon), while also teaming up with the boss of Team Skull himself.

She defeated Red/Blue.

And she gained ability to visit various alternative worlds and dimentions where she can catch ultra beasts and every legendary pokemon in existence.

Yeaaahhhh... from all main characters in pokemon games, Lady Moon is certainly on the top. She's a living definition of epic.
