Weirdboy Tower
Oh boy, you thought the Spleenrippa looked impractical? You thought the infamous dick gun of a Gargant was goofy? You thought that the Wardien Dreadknight and the Khornate Lord of Skulls was idiotic? You thought that half of the Daemon Engines from Khorne and Slaanesh was mindnumbingly retarded? You thought the Imperial Taurox was stupidly high? Well buckle up because you are going to be in one hell of a ride. Ladies and gentlemen meet the Weirdboy Tower.
Now it is understandable that Weirdboyz are nervous around the battlefield, what with their chances of accidentally using too much WAAAGH energy which will make their heads and that of any Orks near them to spontaneously explode. So what is the best way to boost up their confidence? Lets make a vehicle dedicated to them of course!
Weirdboy Towers are engines of war used by the Orks. Manned by Weirdboyz, they apparently amplify the Psyker's psychic powers and create havoc across the battlefield.
The reason why this is mocked is because it looks stupid. It is too damned tall and a slight breeze in the wind should be enough to topple it over. It also looks like a moving dick with herpes...maybe Slaanesh was involved? And that is without going into the fact that it lacks barely any secondary weapons to defend itself. Its only gimmick is making the Weirboy powers super powered, but it doesn't really guarantee it will prevent an explosive 'eadbanging and it is a massive target.
The only good news is that it has been almost forgotten by GeeDubs for decades now.
