What characters have shown up in the New 52's Earth 2? I know that a lot have:

Here are the characters I know for sure:

Flash, Hawkgirl, Green Lantern, Dr. Fate, Superman II, Batman II, Mister Terrific, Red Tornado, the Atom, Mister Terrific, Red Tornado, the Atom, Sandman, Commander Kahn, Judo Master, Red Arrow, Jimmy Olsen, Aqua Woman, Wild Cat, Commander Steel, Terry Sloan, Mister Miracle, Big Barda, Fury, Huntress, Power Girl, Lee Travis/ Crimson Avenger and Wing, Robot Man, Stormy Foster, Steppenwolf, Bizarro, Daseed, Doctor Bedlam, Beguiler, Harley Quinn, Soloman Grundy, White Lantern, Mongul,

Comicvine was saying that lots of other characters were in it like Shining Knight, Spectre, Stripes, and others. But I cannot seem to find a complete list. Comicvine says that Spectre and Shinning Knight, and others have appeared but that might be talking about pre-New 52 Earth-Two.
