The X saga occurs something like 100+ years after the classic series. All of the classic characters are dead by that point, though how each meets his end is unexplained. The only character still alive from that era IIRC is Zero, who was Doctor Wiley's final major project.
Anyway, I personally definitely want the classic Mega Man above all others. Since hes the original, the one who started the series, I feel its most appropriate for him to be the one to represent the series in a game like Brawl. I personally hope for a move set along these lines:
B: Mega Buster - Self-explanatory.
^B: Rush Jet - Rush quickly 'ports in in jet form beneath Mega's feet, carrying him upward and forward and damaging foes he rams. (Since Sonic has his spring for an up B, I feel this is more appropriate than the Rush Coil.)
>B: Power Steal - Mega Man grabs a foe and syphons their power to obtain a move for this slot. Moves would be taken from the classic Robot Masters and based on the enemy grabbed (example: Sonic would yield the Metal Blade, Mario the Fire Storm, Samus the Crash Bombs, Pit the Air Shooter, etc).
VB: Having trouble with this one. Perhaps his classic slide maneuver, with a kick extended for damage? Sounds more like a dash attack though. Maybe something with Rush, or just one of the Robot Master powers that doesn't get used as a stolen one (Skull/Leaf shield? down moves are often defensive, after all).
Final Smash: Having recently played Mega Man 7, I've decided I fully support the Super/Rush Adapter for this. Jet boosters give him gliding and change his up ^B to a flight move, his Mega Buster's charge becomes that ranged fist shot, all moves are powered up, etc.
