I played a lucas player earlier today, things i noticed..
1) Like Trozz said his Up A murders olimar, he ran up and C-Sticked me, odd I had the shield on to, shows how much power that one attack has.
2) all depends what type of lucas your playing, some lucas will fall to the ground and avoid you when hit up, other will LOL and try to hit you with their gun feet, if they attempt this terrible attempt at a down Arieal, just juggle them.
3) => B Pikmin Throw > Lucas anything
Bat - Stopped
PK Fire - Stopped, and to boot, if its red, lucas now has a
pikmin on his.
PK freeze - just dodge, his lag afterwards makes him vulnerable.
PSI magnet - lol wut
PK Thunder - Unless hes recovering there should be no reason for him to really use this, unless you come to an edge stall, (your on one side of the stage, and hes on the other)
4) grab him, don't fall for mind games, lucas can easily run up and do his up A or his hexacon, ***** slap or w/e that is. just don't give him a chance to do any as both are pretty affective.
P.S. Lucas is one of the many characters that have "SPIKE ME" written on them, when he trys to recover via PK thunder, don't let him, send the cowlick boy wonder flying
