This was the name of the talking cat
that helped Alis
in the original Phantasy Star
video game on the Sega Master System
Myau can be found in a shop in Paseo
and you must trade the Laconian
Pot from Camineet
in order to obtain him.
Myau's spells don't do any damage, all of them are support spells.
Later if you feed Myau a certain nut it can turn into a giant flying cat
.. i kid you not
