Those are both really great but that Firestorm is outstanding!

Also, I enjoyed the WIP pics as well.

Yeah. This is gonna be a bit difficult. It will have to be unique for each Black Lantern. I can only think of applying the ability by a trait. Each BL would only get bonuses against characters with keyword on specific teams they knew while living. This would keep the BL pieces with only the 2 keywords you have assigned. Black Lantern and Monster.

This will make them very comic accurate. As you have them designed so far, their attacks do not get above 10 and 9s will probably be common. So the 'inside information' boost will make them dangerous in the right situation only. And more dangerous against other DC characters they knew while living. But only them.

If you get a chance to just pick up the core BL issues. So far 6 of 8 in issues. You will see just enough to understand that the BL are specifically to bring living characters emotional levels to peak before harvesting their heart/emotions.

Give some more thought to the uber-outwit that Firestorm has. I think you can find a way to make it more balanced and still comic accurate.

Keep working on the ideas. Both sculpt and dial ideas are great work from you.
