I'm always up for a build! Let's do this! I've got me an idea for a paranoid rigger who keeps his drug lab in his Bulldog.
I assume you will want to use this from Arsenal...

OPTIONAL RULE: CHEMISTRY ACTIVE SKILL
If the use and abuse of chemicals is going to play a large role in your campaign, you may want to consider transforming Chemistry from a Knowledge skill to an Active Skill (part of the Technical skills category):
Chemistry (Logic)
The Chemistry Technical Active Skill governs the use of and understanding of the properties of matter. It includes proper laboratory procedure and the ability to read chemical formulae.
Default: Yes
Skill Group: None

Concept:
I, personally, was disappointed by the lack of a cheap drug for enhancing Agility (2,000 for P4M0? I don't need that all week!). So this was kind of a way for me to get one.

This "apothecary" has created a new drug which raises Agility stats by 1. The drug is named after its creator, Nim Bull, who himself is only averagely nimble. He is just starting to distribute his invention, but needs to make a quick buck on the side to pay for the investment loan he took out. His contacts represent those he will be distributing to.
Basically, the deal with his van, and his rigging skill as a whole, is kinda complicated and maybe mostly fluff. He is Paranoid, and so lives out of his van and is constantly changing garage locations, as opposed to actual homes. His van serves as his drug lab, as well. It has Electromagnetic Shielding to hide his actions, and he only uses a direct wired link to access it and his drones, accept for his Doberman, which he simply Commands. The Micro-tapper allows the Ferret to use its sensors outside of the van and share them through a fiber optic connection. A fiber optic port in the armrest of the Rigger Cocoon connects him to the van through his cyberarm; another in the headrest connects to the jack in the back of his head, and has another port on the outside that the Micro-tapper uses.
He got a modular lower cyberarm because he appreciated its functionality and capacity to hide certain substances. The large compartment normally holds the Elan, and the small one holds doses of Nim Bull when he's distributing.
Everything else is sort of fluff and generalization, which I think is important in a street-level campaign. You don't survive on the streets by being a munchkin.
I know that this character does not fit the "mastermind" idea, but I still like him. A mastermind would probably need more Charisma and would have to be more trusting (Not paranoid).
