McViper Clan

The McViper Clan is a group of fictional characters created by Carl Barks for The Walt Disney Company. They first appeared in Uncle Scrooge #56 in The Mystery of the Ghosttown Railroad. In that story they try to scare Scrooge McDuck and his nephews with real ghosts to warn them of the evils of this town. They can control ghosts with mind control. They learned how to do this on the road as traveling salesman. One day they were bartering with a local scientist. The scientist gave them a potion that gave them mind control, in exchange they gave him a pint of clam's blood a very rare item. Actually only one of them appeared in that story and his name was Copperhead McViper. Another McViper by the name of Snake McViper appeared in The Cattle King in Uncle Scrooge #69 where he tried to antagonize Scrooge and his nephews. Surprisingly Snake is a pignose and not a dogface like Copperhead. Don Rosa used The McViper Clan in The Life and Times of Scrooge Part 3 where two of them who go by the names Snake Eyes and Haggis infiltrate Murdo Mackenzie and his posse while they plan to rustle Murdo's prize bull Vindicator but Scrooge outwits them. This is supposedly the first encounter that Scrooge has had with The McViper Clan. Either Snake Eyes or Haggis is the father of Copperhead but it is unknown which one. In Part 11 Copperhead and two of his brothers try to steal some papers from Scrooge but they don't succeed.

The name McViper is a pun on the word viper which is a type of snake.

All of The McVipers Names have references to snakes except for Haggis which is a Scottish dish.

Snake is obviously not related to the rest of The McViper Clan. He just has the same last name as the rest of them since he happens to be a pig and the rest of them are dogs.

It is unknown whether or not The McViper Clan appeared in any stories other than the aforementioned stories written by Carl Barks and Don Rosa.
