Mordekaiser used to be the Master of Metal

Ryze used to be the Rogue Mage

Trundle used to be the Cursed Troll

Sion used to be the Undead Champion

Tristana used to be the Megling Gunner

po p py used to be the Iron Ambassador

Taric used to be the Gem Knight

Yorick used to be the Gravedigger

Warwick used to be the Blood Hunter

That's all I can think of, or you can just use Kassyndra's link :,D

Only one of these that wasn't accom panied by a relaunch was Mordekaiser, whose name got changed with the Shadow Isles-lore revam p a while ago because a fan suggested it.
