I think I'm showing my age but I had no idea what HeroClix were when I saw the Vampirella figures on eBay! But I bought them anyway ...
According to WikiPedia "HeroClix is a collectible miniatures game produced by WizKids, Inc. Each
player constructs a "team" of
heroes and villains with certain abilities, skills and weaknesses. Each players take turns to utilize those abilities and skills to "KO" other players' characters.
"Each HeroClix figurine is modeled in roughly O scale and has statistics associated with it: Attack Value, Defence Value, Speed, Damage, and Range. These statistics are all printed on a dial that serves as the base
for the miniature. When a piece takes "damage", its base is twisted a number of "clicks" counter-clockwise, revealing changed (usually decreased) stats to correspond to the damage it has taken. Some characters actually
get stronger with damage, though, to represent a transformation or rage. There are approximately 3,000 different Heroclix figures, as at 1st August 2007.
"Pieces have point values associated with them. Typically, the more powerful the character, the more costly it is to play. Opposing teams must consist of a total point value in pieces that is less than or equal to a pre-decided
total, usually a multiple of 100. Battles are played out on maps, overlaid with a grid of 35mm x 35mm squares."
So now we know! The three figures below won't be taking part in any competitions but will be sitting in my collection alongside a variety of other statues/statuettes.
