The man who calls himself Geist — as in German for ghost — is often asked why he's lurking around at night dressed like a cross between a ninja warrior and an Old West gunslinger. He understands the onlookers' curiosity, but he thinks the query is off the mark.
The critical question is not why he's doing it, he said. It's why other people aren't.
"Why not do good just for the sake of doing good?" he said.
Geist is part of a community of flamboyant do-gooders who call themselves real life superheroes (RLSH), a phenomenon that springs from the intersection of real life and comic books.
Clad in outlandish costumes, they dedicate themselves to helping those in need through a wide range of missions that range from providing food for the homeless to patrolling city streets in the dead of night.
They're the subject of the book "Heroes in the Night," by Tea Krulos, who estimates that there are 200 to 500 of them across the country. (It's hard to get an exact count because of their demand for anonymity, Krulos said.)
One of the more active chapters, called the Great Lakes Alliance, is based in Minnesota. Geist and a fellow member of the group, known as Razorhawk, will join Krulos at a book signing Sunday in St. Paul.
"It sounds crazy," Krulos admitted of the real-life superheroes' behavior. But "they're actually shockingly normal. The image people have of them is that they're young, dorky guys who live in somebody's basement. But there's a lot of diversity in terms of age, professions, politics and religion. Yes, what they do is a little eccentric, but they are basically kindhearted people."
