Re: Yep, "Super-Ventriloquism"
To the point it was more of a running gag than anything else.
In Morrison's Brotherhood of Dada, there was a character called "The Quiz", a Japanese woman with every power you've never thought of; as you think of a power she loses it, but until you think of it, she has it. So when fighting her people spend most of their time thinking of pwoers, so they can deny her their use. Just about the one power EVERYONE who faced her thought of was "super-ventriloquism" :)
