List of all the champions with first and last names.
So after spending some time on the boards, I got interested by Towboat421's post regarding Draven's and Darius's last names, which lead me to asking myself the following question: How many champions have known first AND last name? And well, here it goes, ranked by regions (if I missed some/got few wrong, let me know and I will fix it). For clarity purpose the display will be the occidental naming patern (First name then last name). EDIT: I've also added champions with a confirmed first OR last name that differs to their in-game names.
-Bilgewater-
Sarah Fortune (Miss Fortune) Malcolm Graves Tobias (Twisted Fate)
-Demacia- Sona Buvelle Garen Crownguard Luxanna Crownguard (Lux) Galio Justice Justice Fiora Laurent Jarvan Lightshield IV Shauna Vayne Xin Zhao
-Icathia-
Saijax Cail-Rynx Kohari Icath’un (Jax)
-Ionia-
Shieda Kayn Konte Riven Irelia Xan
-Noxus-
Evaine (Leblanc) Cassiopeia Du Couteau Katarina Du Couteau Talon Du Couteau (Adopted) Annie Hastur Jericho Swain Elise Kythera Zaavan
-Piltover-
Camille Ferros Cecil B. Heimerdinger Ezreal Lymere (Supposedly) Orianna Reveck
-Shadow Isles-
Yorick Mori (No longer confirmed as canon)
-Shurima-
Azir Omah Sivir Omah (Supposedly)
-Zaun-
Janna Windforce (No longer canon) Zigmund (Ziggs)
-Other-
Ivern Bramblefoot
EDIT2: I've added underneath champions with no last name but that rather refer themselves with their tribe/clan/etc.
-Killash Tribe-
Rengar
-Lothlan Tribe-
Rakan Xayah
-Marai Tribe--
Nami
-Nassaj Tribe-
Taliyah
-Shimon Tribe-
Kong (Became Wukong after becoming Master Yi's apprentice)
Out of 141 champion, only 24 have both a first and last name that is confirmed as canon, 3 are no longer confirmed as canon and 6 don't have a last name but refers themselves with their tribe name.
I think this needs some work.
