For my White 2 playthrough I named all of my team members after characters from Arthurian legend, mostly based off the Once and Future King, not so much Morte de Arthur. So I had

Arthur the Samurott
Lancelot the Lucario
Guinevere the Roserade
Morgana the Zoroark
Gawain the Arcanine
Mordred the Electvire

When I caught Kyurem and Reshiram, I named them Uther and Merlin, respectively.
