Champions Online will be almost as similar to Champions as Dungeons and Dragons Online is to Dungeons and Dragons. Which is to say, they are keeping the names and using an entirely different set of mechanics.
To compare this system to others, there is no such thing as a “Dark Blast” or an “Ice Blast” in the HERO System.

In Champions Online, we will have Dark Blast, Ice Blast, etc.
