The Tyrants were pretty cool too, giving an early timeline appearance to a Doom Eternal enemy and also sort of semi explaining why we keep seeing the Cyberdemon over and over again, which is that he is quite literally being mass produced after his death in Shores of Hell for the sake of the demonic war effort, and all tyrants are is simply cheaper, quicker to make replacements forconstantly bringing back and making flesh copies of the Cyberdemon over and over again.
