Noo... REAL LIFE.
I just said this GALAXY, Not the UNIVERSE.
Oh, well then, you'll never find your Pikachu.
Our sun happens to be the exact right size for its luminosity to be what it is, allowing Earth to be nearly 93 million miles away and thus not go into a tidally locked down state, in which case it always faces the same side toward the sun. Our sun's size also allows for its radiation in the red and blue parts of the spectrum to be balanced, allowing efficient photosynthesis to occur.
Yes, our sun is exactly this right size, and it's among the top 10 percent of the most massive stars in our galaxy. Red Dwarfs make up somewhere around 80 percent of stars, and the other nearly 10 percent is made up of stars usually smaller than the sun.
^If our sun was any of those around 90 percent of other stars, life wouldn't be possible, for the reasons said earlier.
....And to make things even more difficult, our solar system is in a small sliver of space in our galaxy that is safe for life to exist. Many areas toward the outer edges are active in their star formation, which destroys and chance of life being there. In the center of our galaxy is a massive black hole, and black holes emit devastating radiation.
So yeah, sorry Pikachu. ;p
