A custom Kill Team boss fight designed around the modern NPO/Joint Ops style using the Tyranid Deathleaper as a stealth-horror nemesis that repeatedly vanishes and reappears.

I have tried to convert its major 40K identity - Infiltrator, Stealth, Lone Operative, Fear of the Unseen, Feeder Tendrils - into Kill Team equivalents focused on concealment, threat spikes, and disruption rather than raw stat inflation.
