Joining the HeroesCon 2010 Guest List today is fan-favorite cover (and sometimes interior) artist Greg Horn, who is known for his stylized cover ladies, especially for Marvel Comics. But more recently he’s been doing more DC stuff, including Blackest Night: Green Lantern Corps variants, Wonder Woman, Justice League: Rise and Fall, and many more. But he’s been doing covers forever, notably on Marvel titles like She-Hulk, Ms Marvel, and more recently Dark Avengers.

Also new today are a ton of creators who work with longtime writer and editor Renee Witterstaetter, who is often identified with fellow guests Michael Golden and Mark Texeira. Renee has been working in comics since the 80’s on titles like Superman and She-Hulk. More recently she’s been co-produding the “Creators Chronicles” series of DVD’s, spotlighting popular comics artists like Mike and Tex, as well as George Perez, Bill Sienkiewicz, Joe Jusko and more.

Joining Renee are artists Steve Scott (Magick, Exiles, Marvel Adventures: Hulk), Leo Leibelman (Heavy Metal), and Creators Chronicles co-producer Robin Dale. These guys practically have their own little island in Artist Alley these days. And they’ll be joined by longtime guest and Art Auction favorite Buzz, who beside being an in-demand pinup and commission artist, has worked on comics including JSA, Atomika, and Vampirella.

Whew! Still tons more creators to announce–stay tuned!
