The picture to your right shows my best guess as to who makes up the team of seven Legionnaires stranded in the present in the current JLa/JSA/Legion crossover. The clues I used to come to this conclusion are mostly cryptic Starman Quotes from Justice League of America #8::

• Karate Kid: Appears in JLA #7 & #8
• Star Boy: Appears in JLA #8, JSA #1-#4
• Dream Girl: "I know that place. Arkham. That's where they have her. My dream girl." Also she appears at the end of JSA #4
• Dawnstar: "The angel is close. The white angel's screaming." "The angel screams in C-Sharp." Also she appears in JSA #1
• Lightning Lad: "She's screaming at -- (Lightning Lad for the interlac challenged)"
• Timberwolf: "Then the wolf howls-- in B-flat"
• Shrinking Violet: "itsy...bitsy..."

Runners up:

• Cosmic Boy: "C-sharp" "B-flat"
• Spider Girl: "itsy...bitsy..."
• White Witch: "The white angel's screaming."
• Tyroc: all of the musical references.
