Legion cameo in 52 Week 3

The Legion makes a surprise cameo appearance in "52" week 3 this week. In the backup "History of the DC Universe" feature, Donna Troy/Wonder Girl/Troia is reviewing a segment that starts discussing the difference between Earths One and Two.

• Computer: You are uniquely connected to a thousand universes, Donna Troy, but they no longer exist.
  
• Troia: Show me what does exist. My friends.
  
• Computer: Researching. Your life most closely reflects that sen on Earth-One with your involvement with its Teen Titans. That was a group that emerged amid a great wave of heroes. The Doom Patrol. Adam Strange. Metamorpho. Hawk and Dove. The Creeper and Batgirl. Earth-One experienced a surge of heroes that surpassed anything Earth-Two would experience -- stretching 1,000 years into the future when the young Legion of Super-Heroes policed the galaxy.
  
• Troia: All this would be extinguished?
  
• Computer: Scanning relevant databases. Portions of that would survive.

There's a shot at the bottom of the page showing the pre-Crisis Adventure-era Legion: Star Boy, Lightning Lass, Sun Boy, Element Lad, Mon-el, Chameleon Boy, Triplicate Girl, Invisible Kid, Cosmic Boy, Saturn Girl, Lightning Lad, and maybe Timber Wolf.

• Computer: On Earth-One, Life progressed and evolved. The young aged and ushered in a new era of greatness. Though evil surfaced -- life continued. A future was established and remained intact on Earth-One.
  
• Troia: And Earth-One's future survived?

On this page we see the New Teen Titans, Darkseid and Orion, Geo-Force, Blue Devil, and the Warlord. Then there's a shot of the pre-Crisis Cockrum-era Legion: Chameleon Boy, Duo Damsel, Bouncing Boy, Saturn Girl, Timber Wolf, Brainiac 5, Element Lad, Dream Girl, Superboy, Star Boy, Phantom Girl, Colossal Boy, Wildfire, Lightning Lad, and Cosmic Boy.

Next page, she's still talking to the computer:

• Computer: Yes, but only partially.
  
• Troia: But... how is that possible?
  
• Computer: A threat unparalleled in scope would soon eradicate the vast majority of existence. The crisis to come would usher in a wave of infinite deaths on infinite worlds.
  
• Troia: What you said -- it's impossible to comprehend. Even now I find it hard to believe that it actually happened. And I was there!
  
• Computer: In its wake, precious few would be spared. No life would go untouched.
