I'm a big fan of Serena and Darien as well but I will use the Japanese names in some cases depending on what I'm discussing with someone and depending on if I actually remember them like in the cases of Serena and Darien I will use those names in reference to the DiC and Cloverway dubs but otherwise I will use Usagi and Mamoru as their names.

Same thing with Ami instead of Amy
Minako instead of Mina
Rei instead of Raye
Mako (or Makoto) instead of Lita
Haruka instead of Amara
Michiru instead of Michelle
Setsuna instead of Trista

Kunzite instead of Malachite

Chibiusa (or Chibi-usa or Chibi-Usa) instead of Rini.

Dark Kingdom instead of Negaverse. (this is one exception I will make, I will always refer to this as the Dark Kingdom regardless of the version I'm discussing)

Queen Metallia instead of Negaforce. (this is another exception I will make, it will always be Metallia instead of Negaforce)
