Thunderball's ball and chain

Thunderball's ball and chain is a fictional mystical weapon featured in comic books published by Marvel Comics. Although it primarily appears in the Thor line of comic titles, it made its first appearance in Defenders #17 in November, 1974. For purposes of clarity, Thunderball's ball and chain is not intended as a rude nickname for Thunderball's significant other.

Abilities

 * Invulnerability: The ball and chain is mystically endowed and is well-nigh invulnerable. The chain that is attached to the ball is likewise unbreakable.
 * Superhuman strength: When wielded as a weapon, the invulnerable ball commits bashing dashing equal to that of someone with superhuman strength. The extent of this damage is also contingent upon the strength of the wielder, in this case, Thunderball.
