Mega Evolution Pokemon in Pokemon Sun?

So, I’m finally playing Pokemon Sun entirely after everything has been spoiled, but, I managed to keep myself unspoiled. So, although I’m not 100% sure if Mega Evolutionisin the game, but, I would like to have a Pokemon capable of Mega Evolution in my in-game Party. To give a bit of context, here is my in-game team so far. You can simply change a slot for the Pokemon you feel that can fit. If you can, please suggest the Pokemon and where it can be found on the one of the islands.I know now Mega Evolution is post-game content, and that’s fine, I’m simply wondering are there any Pokemon I can catch now before then, and where can I find them. Like, for example, Haunter, Electrike, or Sableye.(I’m right smack-dab in the middle of raiding the Aether Foundation’s headquarters as well.)
