I'll be honest, I'm one of those people here in the Doom Community who isn't entirely ok with killing good ol' Commander Keen in Doom 2. I know it's both a reference to the Keen games as well as Adrian Carmack's revenge against doing the art for the Keen games, but it still doesn't feel right to me. It may have been a cute Easter egg back then, but it just feels off now since Keen's been off the radar for so long. But that's just my personal thoughts, and you may or may not share my feelings.
Anyway, I could just replace Keen with another hang-able character, right? Not really. While there are a few decent replacements out there (Jazz Jackrabbit, DN 1 Duke, and even Justin Bieber), but let's face it, that's not very much to work with. You think that people would have made more Keen replacements over the years, but that doesn't appear to be the case. So where are the Keen replacements? Where's a hanging Wolf 3D Hitler? Or how about hanging marines for sick, yet dramatic irony?
Although, I did get the idea to replace the Keen actor with a monster instead. In this case, I picked the D3 Wraith off Realm667 (I wanted to pick something that had some part of Doom's Legacy, and the Forgotten Ones were too similar to Lost Souls to be practical, and Trites are too weak to be useful in this regard). Problem is, even if you kill the four Wraiths that replace Keen, the final exit in Grosse won't open and I'm uncertain how to fix this.
