T-Pose Zombies

T-Pose Zombies appear as the group of antagonists in the SMG4 blooper, SMG4: Mario And The T-Pose Virus. T-pose zombies are a horde of zombified characters stuck in the "T-pose" reference pose that attempt to infect the entire Mushroom Kingdom.

T-pose zombies are formed through a virus that has two vectors of transmission: being killed in proximity of a T-pose zombie or consuming a poisonous T-Pose Shroom.

The T-Pose Zombie was created by Waluigi when he give Shroomy a T-Pose Shroom.

Personality
T-Pose Zombies appear to be completely devoid of personality, instead being a mindless force concerned solely with the propagation of their kind by killing anything that is not a T-pose zombie. T-Pose Zombies rarely (if at all) demonstrate any form of intelligence, doing little more than simply chasing a target for infection. Owing to their low intelligence, T-Pose Zombies do not change their expression at all, even when being assaulted or capturing a victim, showcasing their lack of cognizance. T-Pose Zombies do not put their arms down for any reason, and in fact appear to be completely incapable of having their limbs moved at all, as seen when Meggy attempts to fight her way out of a T-Pose Zombie horde. T-Pose Zombies also appear to be extremely resistant to any form of damage and might not even feel pain, as they quickly got back up after Meggy knocked them all down during her fight in Peach's Castle.

History
The T-Pose Zombies have only appeared in one blooper, SMG4: Mario And The T-Pose Virus. It is unknown if they will return in a later video.

The first known major outbreak of T-Pose Zombies occured in their debut appearance and was caused by Waluigi, who encountered Shroomy in a forest and conjured a T-Pose Shroom using his Staff of Rejection. Waluigi commanded Shroomy to eat the T-Pose Shroom, which he went along with, turning Shroomy into patient zero for the T-Pose virus.

Trivia

 * The concept for the T-pose zombies is a reference to the "T-Pose" meme, where characters are shown in a reference pose with their arms sticking out, making their bodies (sans their head) form a "T" shape.
 * There appears to be no limit as to who can be infected by the T-pose plague, judging by the crowd shots. Characters such as Bowser and Whomps get infected, and even characters with reality-warping abilities such as Baldi and Master Hand are shown to be victims of the T-pose virus.
 * T-pose zombies function similar to the zombies depicted in the Max Brooks novels The Zombie Survival Guide and World War Z, where they are infectees of the "Solanum virus" that are completely devoid of personality or intelligence beyond animalistic instincts and solely focused on spreading the virus and the consumption of humans.
