Elektra was the first one I ever did for Shadowrun. She was also the only one that I ever documented for that system.
Role-players could argue about which system is the best for near-future, cyberpunk adventuring. And they'll mostly agree that Shadowrun was the best of it's time. Wizards of the Coast has introduced a Modern version of their D20 system, as well as a supernatural expansion- Urban Arcana, which together eliminates the need for a Shadowrun product in today's market.
I do reccomend at least checking it out, though. The character generation was one of the most original concepts. And it is very inspiring.
Anyway, I now present to you...
Elektra was to be used as a contact for the player characters to get information in case they got lost. She also could appear at any given time to bail them out if they found themselves overwhelmed by their opponents.
