Sad to find out that probably one of the most likely matchups in Sparking Zero to have unique dialogue, Frieza vs Frost, got basically watered down to Frieza using one of his mirror match dialogues and Frost having a generic reply. My boy's been SNUBBED I tell you.
In other intro dialogue developments...
I still need to know if Hit and Frost have dialogue. With the uploads I've seen, I can't tell if there just isn't a conversation for a certain combination of characters or it just hasn't been posted/tested yet.
RIP "Lookin' good, Tien" "Lookin' good, Yamcha"- the two still have a unique convo but a different one. It probably wouldn't hit the same with some of these intro animations taking excessively long (cough, cough, Perfect Cell).
Frost and King Cold dialogue! For some reason! He wants to make Frost his new son, Frost respectfully declines, then when King Cold wins he's like "well, I asked nicely... you are my new son now effectively immediately". Can't tell if he's trying to adopt Frost or arrange one of his sons' marriages.
