Deathwalker

Na'Toth asserts that Deathwalker was a war criminal responsible for a number of unethical and illegal experiments on the Narn people during wartime.

In Medlab, Sinclair identifies the woman as a Dilgar, a species that had previously gone to war against many non-aligned worlds, but had died out thirty years ago when their sun went nova.

In Medlab, the woman wakes up and affirms she is Jha'dur, otherwise known as Deathwalker, but indicates that she has come for a different purpose: she has started development of a drug which will give its user immortality.

Sinclair offers their representatives a compromise, explaining about the immortality drug and allowing their scientists to participate in its development, after which Earth will turn Jha'dur over to them.

She tells him that the truth about the immortality drug is that its principal component requires the death of another, and she sees its success as her legacy: namely that the other races will turn on each other like wolves, and become savages as has she.

Talia finds that she is unable to read anything from Abbut with her telepathic abilities, and as she listens in, he and Kosh speak in seemingly nonsense phrases.

Frightened out of the vision, she finds that Abbut has concluded his deal: he takes a data crystal out of his cybernetic brain and gives it to Kosh then departs.

Robyn Curtis had earlier appeared in the 1993 comedy film Hexed, which had starred Babylon 5 main cast member Claudia Christian.

The Babylon 5 makeup department involved in this episode – consisting of Everett Burrell, Greg Funk, Mary Kay Morse, Ron Pipes and John Vulich – won the 1994 Emmy Award for Outstanding Individual Achievement in Makeup for a Series for episode 5 of the season, 'The Parliament of Dreams'[2] For its visual effects scenes, Babylon 5 pioneered the use of computer-generated imagery (CGI) scenes – instead of using more expensive physical models – in a television series.

"[7] The saucer-shaped alien ships, which emerge from Babylon 5's jump gate and threaten to fire on the station, were also designed by Thornton, containing animated rotating sections, with oversized guns added "for a giggle".

[8] The Ishka ship with the globe-shaped power source in the center was also created by Thornton, who wrote that Straczynski had originally wanted the it to be ball-shaped.

The episode also develops the concept of the mysterious Minbari Warrior Caste – about which the series has revealed very little previously – and the Wind Swords clan, who seem to know about Commander Sinclair.

Club, writes there are problems with the premise that the immortality serum requiring the death of another to work, including that the science would essentially be magic.

"Deathwalker is easily the most unambiguously evil character in Babylon 5 so far ... none have (so far) been motivated by pure spite and the desire to see the whole universe suffer.

"[14] Rosner also points out how the episode shows how the mere promise of immortality gave a single individual control over not only one major power, but many: "Think about it.

[14] Jules-Pierre Malartre, writing in the science fiction review site, Den of Geek, comments that 'Deathwalker' made the viewer want to see more of the Dilgar, and the war they waged on the other worlds.

Malartre highlights the risk of progress at the expense of our humanity: "'Deathwalker' is a very good argument of the cost of scientific advancement on the moral values of a civilisation.
