Young Justice trivia!

Some months ago I posted some trivia facts about the Young Justice characters and now I think it'll be nice if I posted more trivia facts since a lot has been since the last time I did the character trivia. I will be posting more trivia and if anyone knows any awesome trivia facts, leave a comment writing what it is and I will post them in the next trivia post :]

• Kelly Hu is the voice actress for Chesire, who also voices Paula Crock (Artemis' mother)
• Kaldur'ahm does not live in Poseidonis, the capital of Atlantis. He lives somewhere else in Atlantis
• Kaldur's mother will appear on the show
• Superboy has an encylopedic knowledge of World History
• The current Black Canary was the daughter of a previous hero that used the same name. The original Black Canary was born in 1943. She gave birth to the current Black Canary when she was relatively old
• Miss Martian has seventeen brothers and roughly 300 cousins.
• Miss Martian is trained in CPR
• Batman is the leader of the Justice League, having been formally elected
• The League of Shadows is a criminal and terrorist organization led by Ra's al Ghul
• The Justice League was founded about seven years before the beginning of the series, but the public has only known about it for 3 or 4 years
• Greg Weisman (producer of YJ) stated that he chose Dick Grayson as Robin because Young Justice was sort of a Robin origin story and putting Jason Todd or Tim Drake would be doing injustice to the series.
