The X-Men have a pretty great roster of characters, but Wolverine (a.k.a. Logan, a.k.a. James Howlett, a.k.a. Weapon X, a.k.a. Patch... we could go on) would win any popularity poll hands down. What's at the root of Wolvie's favored fan status? It's as simple as his characterization: he's a badass individual with unbreakable claws that can cut through anything, which are mainly used on bad guys.
