Shadow Dragon
Converted to 3rd Edition by Strenoth@aol.com

Appearance, climate, etc... as per 2nd Ed Monster Manual or as standard for Dragons per 3rd Edition Monster Manual. The only information here is 3rd Edition statistics that are specific to the Shadow Dragon. For general information and abilities, you must have the Monster Manual
 
Alignment: Always Chaotic Evil 

Challenge Rating: I would use the same table as a Blue Dragon (being just slightly less than a Red's. GW Shadow Dragons are worth only 2000 less XP than a GW Red in 2nd)

Immune to Energy Drain: Shadows Dragons are immune to Negative Levels, ability damage caused by negative energy (such as the strength damage of Shadows), and any other effect based on Negative Energy such as Inflict spells, but unlike undead, they are *not* healed by them.

Create Shadows: Range:0, Area of effect: 100' Radius, Duration: 1 hour. The spherical area is filled with Leaping Shadows (all creatures w/o night sight, or attacking beyond range of dark sight, treat their target as having half-concealment, suffering a 20% miss chance.) All creatures effectively have the ability "Hide in Plain Sight", like a Shadow Dancer, while with in the area of this effect. Shadow Dragons, Shadow Dancers, and other creatures of the Demi-Plane of Shadow are able to Hide while attacking, and remaining hidden, and thus are able to attack/defend as if invisible against any creature who fails their spot check. This is especially useful to a Rogue or Assassin/Shadow Dancer, as the 'sneak attack' rules would apply to every strike.

Breath Weapon: Cone shaped black energy mist, blinding as magical darkness for 1 round, and inflicting 1d6 +1 per age category Negative Levels. These Negative Levels last for only 1d6 minutes, +1 per age category, and the target falls unconscious if it takes negative levels equal to it's Hit Dice. No ST is required to avoid permanent Energy Drain. The Dragon gains 5 temporary HP for each level it drains. ST is Fort to get Half of the Negative Levels lost.
(This version seems more in accordance with the style of third edition, though the duration is in minutes instead of rounds, which balances out the lack of a direct damage breath weapon. 
Optionally, 'Target Falls Unconscious' can be changed to 'Target dies' to balance out the fewer levels lost, or negative levels can be 3/4   (1/2 on save) HD of target, as per 2nd edition, but this would also be given the shadow dragon a *lot* of temporary HP, and cripple almost any other dragon.)
