Amphibious Leader (with a number)

Beta Phase (made of dark matter that only weakly interacts with normal matter)

Blood Slaving Bonus (for FoB / units with SDR). This should be a picture of a tentacle monster.

Bane Poision / Bleed (these would explain some mysterious deaths)

Experience (clicking on experience stars could show the unit's numeric experience / kills).

Kenobe Icon (striking this unit down makes it more powerful than you can possibly imagine, for Machaka Black Hunters).

Turtle Icon (shrinks when attacked, like Elementals).

Actually those two could just be a shared "Death Form" icon=)

Prognostication Icon (with a number - chance of avoiding bad events).

Local Scale Icon (affects local scales, like luck or temperature)

Scale Sensitivity Icon (unit is affected by local scales, like Winter Wolves and Ice Devils)
