Mortimer McMire is the grandson of Adolf Hitler
Since Keen is the grandson of B.J. Blazkowicz, who fought Hitler in Wolfenstein 3D, so who knows how far the rivalry goes back? It would also explain some of his beliefs. Mortimer McMire is the grandson of either Dr. Schabbs, or Otto Giftmacher.
Perhaps Mortimer inherited his views from Naziism, but his genius from a scientist instead of Hitler himself. On the one hand, Schabbs seems to be more of the supergenius that would create a mastermind like Mortimer. On the other hand, the McMire name may be a bastardisation/mutation of Giftmacher, which literally translates to "Poison Maker". Molly is dating Billy's older brother
The games mention him having a brother after all. I know there's nothing to support this WMG, but it sure would make Billy and Mortimer's rivalry more interesting if their siblings had the hots for each other (and by interesting, I mean more vomit-inducing for both boys). Keen is a murderous psychopath who really, really hates the Vorticons
In the first two games, all the Vorticons Keen encounters are soldiers trying to blow up the Earth, and thus fair game. Then you discover in game two that the Vorticon's aren't really evil, they're just under mind control by the Grand Intellect aka Mortimer McMire. Unfortunately, you still have to shoot your way through the mothership. Sacrifices have to be made to save the Earth, after all. But then game three rolls around and Keen goes to the Vorticon homeworld to face the Grand Intellect once and for all...but not before rampaging across the entire planet and wantonly slaughtering its inhabitants, including breaking into their houses and schools, killing everything inside (including women and children,) and then eating all their food. Hell, they probably only gave Keen a medal at the end of the game in an attempt to keep him from continuing his killing spree.- Maybe you're the psychopath; it's more than possible to avoid shooting most of the children. The women, meanwhile, breathe deadly fireballs, and are more dangerous than some of the men; their society may well operate on different rules, which Keen would have picked up on.
- The women take the most hits to kill (5) but they're not all that dangerous. They're slower, they don't jump and touching them won't kill you. The only dangerous thing about them is the fireballs, which will disappear if you shoot at them.
Keen was traumatized by his actions on the Vorticon Homeworld, which led to the development of the Stunner pistol.
In a sharp contrast to above, Keen truly regretted the Vorticon genocide he was forced to perform in order to stop Mortimer. Realizing the horror of what he did, slaughtering even Vorticon children, out of necessity, Keen developed the stunner pistol he now uses so that he never has to kill an innocent again. It's designed to be recharged by any standard pistol ammunition, so he can keep it charged no matter where in the galaxy he battles evil. Keen grew up in Nazi dominated America
Billy Blaze or Commander Keen is descended from B.J. Blazkowicz. The Nazis won the second world war in The New Order and subjugated the world. Billy's absurdly powerful rocket is built from tech that was reverse-engineed from Da'at Yichud artifacts. The robed man being held captive in the Pyramid of the Forbidden is much, much more important and crucial than he lets on.
The Billy Blaze from the 2019 game is a young Doomguy
Word of God has stated that Doomguy is the son of the original Billy Blaze. And now as of the 2019 game, OG Keen is an adult with a wife, son, and daughter. This would mean that Doomguy started out as the second Commander Keen, going on space adventures with his twin sister before he grew up and became a space marine fighting the legions of Hell. And considering that OG Keen was born in 1982 and the original Doom took place in 2022, this could mean that the new Keen game takes place in 2008-2010, if OG Keen had children around the year 2000. The Commander Keen games are stories told to a young Doomguy.
Commander Keen’s different tone is because they’re children’s stories told to a young Doomguy by his dad, who’s the son (or more likely grandson) of famous Nazi-hunter Billy Blazkowicz. Billy “Commander Keen” Blaze was a mundane (by the standards of the setting) soldier on Mars. Keen got his Neural Stunner technology from Mortimer McMire
Not intentionally on the latter's part, of course.Keen's ray gun in the original trilogy was lethal, because he hadn't figured out how to build a nonlethal version. To compensate, he kept the weapon uncharged when he wasn't expecting combat. This is why he starts ''Marooned On Mars" with zero charges; he was on Mars to explore the planet, and didn't anticipate his Megarocket getting dismantled by Vorticons.
The Secret Of The Oracle states upfront that the Vorticons shared information with Keen after he freed them from Mortimer Mc Mire's mind-control technology. This would include giving him access to Mortimer's notes and schematics for said technology, the principles of which Keen used to adapt his Ray Gun into a Neural Stunner.
