Character Evolution

Silver Age

Initially introduced in the Silver Age, very little was known about Elsa. Her surname was variously given as Magussen, Magusson, Magnussen, and Magnusson. The character was primarily a love interest who accompanied Mark Merlin and had few known abilities that lent themselves to paranormal investigation.

Modern Age

Reintroduced in the Modern Age, Elsa became a more competent character in her own right; her current skills and abilities were introduced. Her name was given solely as Elsa Magnusson.
