Huh...
Yellow: I usually name him Blue, but in one playthrough I named him ***face.
Silver: When it was originally my little bro's, he named him Lisa because he thought he was a girl (well, my brother was eight or nine...is it still excusable?). However, in the playthroughs after that, I named him Silver.
Sapphire: Brendan. Well, I had no choice, right?
LeafGreen: I went toward the Super Effective path and named him Douche. Then in later playthroughs I named him Kyte. Why the ridiculous variation of the word "kite"? In an old failed fanfic (don't bother looking for it, it didn't even reach the internet), that was the name of his character. You see why it failed?
Pearl: Edward. He looked like an Edward to me.
