Allspeak
All-Tongue
All Asgardians,[1] and other deities in the Marvel Universe,[citation needed] can speak every language thanks to the "Allspeak"[citation needed] or "All-Tongue", in which what they say is understood by every species in their own native language.[1]
X'zelzi'ohr
When Man-Thing was granted speech again he spoke the language of X'zelzi'ohr, the universal language. Everyone heard him in a way they were accustomed to, meaning he spoke "American" to the likes of Satana and Moonstone, but was concise and to the point for Ghost, a lewd Englishman to Mr. Hyde, and a total thug to Boomerang.[2]
