Ok. We've been over how to get from A to Zed on making a caped crusader. Batman himself remains a biggie and unable to be reproduced with RAW.
Now I've a couple of questions for folks. I used to collect comics, I was more a Marvel guy than a DC guy but I've got some general Batman knowledge. My questions to you guys, many of whom have significantly more Batman knowledge...
1) Do other members of the Bat Family have their own Specialty Vehicles?
Yes. Nightwing, Batgirl (all three versions), Huntress, Robin (all versions), and I believe even Spoiler did. I am pretty sure Oracle does too.
2) If so, what are they, and their general Abilities/gadgets?
I recommend you find a copy of "The Essential Batman Encyclopedia" and "Batman: The Ultimate Guide to the Dark Knight" for that sort of stuff. An essay could be written to give you a decent answer.
This is especially true of the Robins, who often had their own vehicles, in addition to Robin Variants (diff color schemes etc) of the standard Bat Vehicles.
And lastly,
3) What abilities/gadgets would you guys consider the 'quintessential' Batmobile? (I know there's dozens of different Batmobiles, but I'm asking if you were to sit down and list out the Quintessential one, what would you give her?)
Armor
Shielding (radar, radiation, etc) out the yin-yang.
Speed to Spare
Run Flats
Fuel Mod (usage, type, whatever)
Bat Computer/Bat Cave Link
Mini Lab
Crowd Control Devices
Major Anti Theft Deterrents (non-lethal)
Powerful Multi Directional Lights
Comms and Sensors out the Wazoo
Secret Compartments all over it.
Remote Control
Safety Systems Extraordinaire (ejector seats, deployable crash foam, integral extinguishers, etc.
