Normally when using TX Convertor to make a character texture, I use A1R5G5B5 if it has an alpha channel. 1 bit alpha is enough to make areas visible or invisible.
It turns out that characters obey 4 bit alpha, to some extent. Photoshop allows the colour to be set by sliders or by typing numbers:
Some experimenting shows that the brightness must be at least 74. At 73, the character is completely invisible. At 74, meet the ghost of Nathaniel Hawk:
Those of you interested in the supernatural can probably find uses for this...
