I found this glitch on console, but if it works on PC, reply below.
To do this glitch, go to the hero gallery, select the hero you want to get a T-Pose out of, then repeatedly press the Hero Info button and back button simultaneously. (Don’t spam or you could accidentally cancel out of the menu.)
However, some heroes don’t have a T-Pose, unfortunately, Orisa might not have one. If you are confused as to how to press the buttons, you should press them both at least once every second.
If you do it correctly, you can briefly see your chosen hero T-Pose as you load up the Hero Info.
I hope you enjoyed this little glitch i found. If Blizzard patches this then there will be backlash. LOTS of backlash.
If you want the best results, try it on Winston’s part of the Hero Gallery, it is the most hilarious one.
