Say I'm creating a character and I want him to be clearly recognizable as a class 100. Aside from slugging it out with an established class 100, (like Classic Thor or Superman) what sort of feats would make that status obvious? Mainly I'm looking at striking/breaking type feats rather than lifting feats, but lifting is also acceptable.
I know there's a lot of variation between class 100s (planet busters are obviously above lower end class 100s by a significant margin) but I'm trying to get a better handle on what the lower-end types can do.
For instance, say that a character can shatter Mt Everest into pebble-sized fragments with a single punch. Would that confer class 100 status? What about 5 Mt Everests at the same time?
How about if a character can punch another character so that they smash through the Earth and break through on the other side of the planet?
