Re: [4E] Worst Disad
My personal favorite, from back in my college days, was someone who made a character with Accidental Change: into a bird (falcon, eagle, hawk?) when captured. Now, it bears noting that the character had no shapeshifting power whatsoever; no Shapeshift, no Multiform, not even Hero ID, though he did have foci*. So, being something of a jerk at the time (rather than just saying 'no'), I 'interpreted' the Disad as turning him into a completely normal bird, including mentally, when activated. So, basically, he'd just start flying around until he was not-captured, then take off for the wild blue yonder.
And then turn back to human.
Did I mention he couldn't fly, either?
*The character was actually *all* foci. All of his stats above 10, every power, and every skill bought through a focus ... a DIFFERENT focus. Dude had bling before the word was invented.
