Zaxopify is correct, about the identities of Nightwing and Robin. As for the catch frases, I do agree that "so crash" sounds cooler than "feeling the aster".

But that is because of the fourty years. The "cool new catch frase" has changed. That, and they're different people, in different situations. Saying "so crash" is basically the futuristic equivalent of saying "cool". Compared to saying "feeling the aster", meaning that "things have obviously changed for the better".
