text: From the late 1980s through the early 2000s, the number of survivors was reduced to Superman himself in the comic book stories (the Eradicator was added in 1989 as a non-sentient device, and shown to be self-aware in 1991), but more recent accounts have restored Supergirl, Krypto, and Kandor and introduced another newly discovered survivor, Karsta Wor-Ul.
