Many thanks to Klaus (dwarf cleric), Lorthanoth (dragonborn fighter), Jack99 (half-elf paladin), Bagpuss (elf ranger), evilhalfling (halfling rogue), Kishin (tiefling warlock), Blargney the Second (eladrin warlord), and RangerWickett (human wizard) for all the character concepts and builds.
If the goal is really to build iconics some "Rules of Iconics" should apply.
1. Iconic characters are the most mainstream build of each race and character class. Stereotypes of each character class should definitely apply with probably an emphasis on the historical build of the class in earlier editions of Dungeons & Dragons.
2. It is not important for each iconic to be the most mechanically optimized build. In fact, iconics are likely better ambassadors for their character class when they are more rounded to the class and less optimized.
3. In order to embody one character class most strongly, iconics can't dilute their message. Thus iconic characters for a specific class should never multiclass.
4. Myth and entertainment (movies, books, &c) have established certain ideals for character classes to aspire towards. Each iconic should work towards the most iconic Paragon path for their class.
5. Similarly with epic destinies, while it might be mechanically better for every class to go for Demigod there are some destinies that are more thematically suited for different classes. To take the example further, probably only divine source characters should choose Demigod.
Bagpuss did an exceptionally good job of using the unspoken "Rules of Iconics" by making the elf ranger capable of both iconic ranger abilities (two-blade and archer fighting). Kishin's warlock is also very iconic by making the obvious choice of pairing a demonic race (tiefling) with a demonic pact (infernal). When it comes to iconic builds the Blood Mage paragon path is probably the least iconic Player Character choice for an iconic wizard build. The blood mage concept remains cool even though it isn't very iconic; that's the difference between iconic builds and just making a character.
Her favorite is a plain gold ring she recently won in a skill challenge. It is always telling her that she is pretty, and Destined for Great Things.
