In the 1990's DC and Marvel did a cross over event and mashed their characters together into "amalgams". The character they combine with Batman was Wolverine to create: Dark Claw.
At that time Wolverine had an adamantium skeleton which was one of the things that helped make him invincible (Batman often suffers from the same problem: invincibility by popularity). I can imagine some side effects to having a metal skeleton. Is weight one of them?
How heavy is Wolverine/Dark Claw with his adamantium skeleton?
