Ever since I was little, I became more fond of Jolteon than the others. Then, I saw Umbreon and thought of it as my favorite. But then, I started thinking about Jolteon again, and then I thought, "IDGAF about Eeveelutions..." But now, that thought has come across me again, and I'll say that ultimately, Jolteon is my favorite. I still like Umbreon and the others, though.
