Here is some scales from your Friendly Cosmic Nucleon;
Spiderman; Now that's agile; A DEX of 30-36 seems okay.
Beast (X-Men fame); 27-32 DEX
Black Panther; 24-27 DEX
Cap American; 21-23 DEX. And a truckload of CSLs
Thor; DEX 17-18. He has other ressources.
Iron Man; Dex 14-15, in or out of armor.
Hulk; DEX 11-12. The Green Behemoth likes to be touched; He's got an Area-affecting clap/stomp to get rid of these pesky speedsters.
Excellent I for one am tired of the dex wars- players need to stick witha concept and not worry about who goes first . I started one campaign and every player wanted to start at 27 dex. So they could have an edge, slow ponderous 4 spd brick 6 spedd martial arrtist , 7 speed movement master etc.
