This is a series of X-Men/Adventure Time character mashups created by illustrator and graphic artist Katie Goodrich. I don't recognize any of them. I think the first one is Geordi LaForge/Gumbi? If we're being honest, I don't really know any comic book or cartoon characters and I'm probably not qualified to be writing Geekologie. I've just always been great at faking it. ESPECIALLY sexually. "He thought he was supposed to put in my belly button." Honey! "More than once." You're embarrassing me! "He tried to tie his penis in a knot so he could last longer." Okay now that I thought would work for sure.
Thanks to Philly, who wants to mash up characters with themselves to make their evil twins.
