>>98048739Its probably the best icon the cake decorators could come up with for Hulk.
Do a GIS for "Hulk symbol" and the radioactive flag is one of the common results. One of the other common ones is a big fist which would be even more easily confused in the context of the Infinity Gauntlet movie. So, poor Hyperion has his official symbol co-opted to be Hulks unofficial symbol.
(Marvel really should do better with their iconography, admittedly)
