Re: Oihid
There are other ways a GM can make this one worth it's salt, too. Captain Marvel got hosed earlier this year when Brainwave used Mind Control to make him say "Shazam" and then Black Adam slapped Billy into unconciousness.
In the olden days, it wasn't too uncommon for people with the Shazam power to get un-Marvelled by another person calling down the lightning (or Instant Changed for that matter).
Let's face it, a GM can basically one-shot your character by changing him or her out of Hero ID. It's almost like having a Fatal Vulnerabilty.
And generally speaking, your OIHID (or HIDO as I prefer) character is also going to have disadvantages that ensure that being in Hero ID isn't always a good thing (Secret ID, Distinctive Features, Hunted, Vulnerabilities, Susceptabilities, ect).
