I remember seeing a Powers and Abilities Chart for the Batman: Alpha game, designed for playing normal HC pieces under the BA ruleset. But I can't find it on the WizKids site. Any help?

Here it is.

Excellent! Thank you, sir!

If you're interested, all of the Alpha documentation (official and unofficial) can be found using the link in my sig.

The Alphaclix Unlimited rulebook might be of interest; among other rules, it fills in the four powers missing from the official Alpha PAC.

Thanks for making up the missing powers! Woooot!!!!
