MCU fans start speculation
One user referred to it as Doctor Doom's "Latverian script," commenting on X (formerly Twitter), "I think it's Dr. Doom's Castle language." Another speculated, "Reed Richards is collaborating on multiverse equations with Victor Von Doom." The connection to Reed Richards, also known as Mr. Fantastic, was highlighted by another Marvel enthusiast. "It seems like it's zoomed way in on something like ... Richards' notes...?!? Or perhaps Moon Knight symbols...?!? Not sure.." they remarked. "I’m going to guess that’s Reed’s chalkboard," read more comments.
A frustrated fan who struggled to decipher its meaning expressed, "Are the Russo brothers just messing with us with this blurry nonsense, or do they owe us all refunds?!" Another quipped, "They are aiming for 8-bit special effects this time." A Marvel fan humorously noted, "Looks like Dr. Doom’s castle has a poor Wi-Fi connection; time to call MCU tech support!" Some even linked it to HYDRA, stating, "It's clearly HYDRA codec signals, guys."
