The Web Spinner was an early Umbrella B.O.W. (Bio-Organic Weapon) which was researched and developed in the Arklay Laboratory. The Web Spinner was created by injecting a sample of the
t-Virus into various kinds of arachnids. It is not known exactly which one was selected to become the template for the Web Spinner but it shares many physical characteristics to a tarantula so it was most likely that one.
Umbrella found the resulting creation to be unsatisfactory as apart from a marked increase in size and aggression, they did not have any other useful characteristics as a weapon. Also, they suffered from a great loss in intelligence which also made them unsuitable as weapon as they could not follow orders or listen to commands. Contrary to their name they rarely spun webs - they relied entirely on their size and formidable bite power in order to subdue their prey.
As with most spiders, they could climb along almost all surfaces with ease and as such tended to hide in the darkness. The project was cancelled soon after it began and most of the specimens were destroyed - a few remained alive to that small teams could continue experimenting on them but these eventually escaped and managed to nest throughout the
Spencer Mansion. A larger mutated Web Spinner was also found in an underground cave system adjoining the mansion to the laboratory. It was given the nickname
Black Tiger due to it's darker colouring and was much larger and more powerful than an ordinary Web Spinner - so much so that the creature was so difficult to kill it couldn't be stopped by UBCS (Umbrella Biohazard Countermeasure Service) soldiers who decided to fall back.
Further research into different ways to create
Spider B.O.W.s was conducted but the Web Spinner project was abandoned.
