Have some ae and HoH questions:

When theese characters change into their alter egos, or other versions of themselves, do they keep...

any assigned feats?
any ATAs?
any special objects they have aquired?
Gauntlet?

Thanks ahead of time for any help!

Yes. They are considered the same character so everything crosses over.

Its just a cooler version of an activation click.

There is a quote somewhere...
