Robert Downey Jr.'s Doctor Doom jacket did more than complete his ominous Comic-Con look. Its bands of fictional Latverian symbols carried a set of messages about justice, revenge and the uncertainty of tomorrow, giving Marvel fans a puzzle that stretched across two conventions and several bags of promotional coffee.

The translation adds another layer to Marvel Studios’ campaign for Avengers: Doomsday, although it does not confirm what any of the phrases mean for the film. It does, however, sound exactly like something Victor von Doom might have embroidered on formalwear.

What did the Latverian writing say?

Popverse writer Grant DeArmitt decoded most of the jacket by comparing its symbols with packaging from Marvel’s earlier “Dom Latveria” coffee promotion at SXSW London. That activation included phrases written in the same invented script, providing enough repeated letters to start building an alphabet.
