List the true combos, or list all the possible follow ups from ever possible move. Not some random combination of both.
I HATE the very concept of "Followups" A follow up is basically something you use after a certain move. Which, unless it is COMPLETELY inescapable, then you have to WORK for that move after the previous move. If you consider this a follow up, then the list would be infinite. An entire Brawl match could be considered one giant followup if you count the hits that you have to work for "follow ups."
After you do a move, believe it or not, you can do ANY MOVE after that. I hate it when people say "Let's analyze the possible follow-ups..." Well guess what, you can do nearly any move after the ending lag of another!
The focus of Brawl is NOT followups, good God, if you hit an opponent, 90% of the time (The other 10 is for random 0% combos and the like) THAT'S IT, NO OTHER MOVE IS GUARANTEED TO HIT. People say it basically resets the position, but that's kind of untrue, one may have a more disadvantageous position after being hit, and you can TAKE ADVANTAGE of said disadvantage by predicting what they will do and countering their move that you predicted with a move of your own. This is not a follow up.
Sorry, kudos to you for putting forth the effort to making a list... but, I personally HATE the very concept of followups.
