Here's an easy one: In Injustice, Batman's fighting stance includes his right hand being held outwards, it's a reference to Scorpion who has always held arm out that way during many of his fighting stances to symbolize a Scorpion's tail (the deadliest part of a Scorpion). I read that fact about Scorpion off the MK wiki a while back, and just made the connection when I saw Batman's fighting stance.
