1) For aerial combat I'm giving this one to Sonic.
2) Weegee is looking good with his Jabs, he can mess with them to whatever he wants, be it his FJP, Dsmash, Usmash, Fsmash (more of a mindgame), A full Jab, a grab, an aerial (Probably N/D/F/Bair most likely [in that order]) a grab INTO an aerial at low %ages, a rab into an F/B-throw, with Back-throw the better killer at the edge, Utilt, Dtilt...well at least that's what I think he can come up with...that's a helluva lot of utility...maybe Mr. L was Batman.
3) His dash isn't so good, I think you can Powershield the last hit? if not that you can SDI into Luigi and end up BEHIND him before he's even done with the sequence.
4) Dtilt can trip you. Utilt leads into more Utilts which lead into more things at low %ages, mainly Aerials. Ftilt isn't so great either...makes them go a little ways, but that's about it...
5) Weegee's poke Fsmash is amazingly fast, it can be made EVEN FASTER when tilted upwards, and has astronomical K.O. power. Break Dancing Dsmash comes out fast, so fast it can be an OOS option for him. Finally his Usmash is also a decent killer.
6) Mach Tornado Weegee Spin Luigi Cyclone can be used for lots of things. It gets him around the stage quickly, is one of his methods of recovery, get's him some vertical distance which can catch you offgaurd and you will end up getting Star K.O.ed if you aren't trying to get back to the ground fast, and just like the Mach Tornado not too many things will easily outprioritize this unless either spaced or something else I have forgotten to mention happens/goes wrong.
7) Weegee was behind 9/11! His Green Missile is yet another method of recovery, but get this! One in Every Eight Green Missiles will Misfire, giving them as much power as a fully charged regular missile...sometimes INSTANTLY! They send him flying further horizontally fast...again sometimes on the fly. This will always catch you offgaurd because it's a random chance, and will kill you if you aren't prepared for it. weegee also mgiht sometimes get stuck in a wall with a Misfire and will probably give you time to punish that.
8) Now for a regular Green Missile, it's not really impressive if uncharged, and even when it is is still not too frieghtening if at all. Add everything to the Misfire and downgrade it, and you have a regular Green Missile.
9) Fire-Jump Punch: Although many Weegee's won't balantaly be using this often, but it is used more as a punisher. If Weegee misses this, it is very easy to punish him in his helplessness state. If he DOES get you with this, start praying that you won't die.
10) Fireballs: To me, Ike can easily handle this...as Sonic, it's a different story. The invincibility frames from SD will of course go through them, however I'm not sure what the other methods of SD/SC compare to Fireball for example. Just get around this brickwall, as Luigi's fireballs defy gravity and can be used to stop you in the air or in the ground, depending on where you try to approach Weegee. Somebody else will have to cover this for me as I'm not too sure how Sonic can get around this and still keep up a good game.
1) Aerial combat to Sonic? You have to remember that even though Sonic's can beat out luigis because of disjointedness, Luigis all come out ridiculously fast, his slowest being his dair if I'm not mistaken. Therefor the only area where Luigi is truly at a disadvantage in the air is when Sonic is below him. Luigis aerials are just too good. You're better off springing to safetly. Sonic can land some aerials by quickly jumping from the ground, but a fight thats actually taking place completely in the air? Unless Sonic is below luigi, Luigis wins.
2) This is pretty much true.
3) I assume you mean his dash attack, and all you have to do is like hold shield and it will usually powershield it before you get to the last hit, no problem with this move.
4) This is true, but you should never be that close to luigi, because dtilt has absymal range. space youself just outside of luigi's range with ftilts. For utilt juggles, DI and spring/midair jump out.
5) Fsmash is ridiculously powerful. Its only shortranged, so again, space with ftilt. I believe ftilt will clang with his fsmash.
6) DownB is very annoying. Yea its like Nado, but it has a smaller hitbox. Just cancel it with ftilt and you'll be fine. But yea, its definately an annoying move since it will either beat out or clang with your SDRs most of the time.
7) For the record, it is random, but with a probability of 1/8 of every green missile being a misfire. And yea, watch out, I've had too many matches when I played my luigi main friend where he would win a match I was supposed to wn by getting lucky with a misfire =(
8) yea, I don't know why a luigi would be using this for anything except recovery, especially against Sonic. If used onstage you can just outrun it and screechstop shield grab/pivot grab/sideB reversal shield grab. I've done this too many times. I love Sonic's speed.
9) This is the number oen reason you should always be moving in this matchup. I think you should always be moving as Sonic anyways, but fire jump punch is a serious prob. Add to that that sonic has significant ending lag on several of his moves, and you'r in trouble. Never SHFF and fair, or whiff a usmash when luigi is on the ground XD.
10) Fireballs shouldn't be a problem. Of course luigi will hit you with them sometimes, but since when does Sonic have trouble with projectiles? Marios fireballs are much more problematic imo. you can spinshot if you need to get in there quick, you can use invincy frames, you can sideB shield cancel, or run and powershield. Remember Sonic runs quick lol, so if you run and powershield, luigi doesnt exactly have much time to get out more fireballls.
Anyways, to me this match up is broken down like this:
Luigi can pwn Sonic in the air if Sonic is not below him. Luigi can kill Sonic very quickly. Those are his main advantages.
Sonic can outrange luigi on the ground, and has the speed to punish alot of luigis stuff. Shielding his aerials and then sliding into grab range will be your friend.
I can't really see the matchup going too strongly in either ones favors. my guess would be 55:45 luig. At worst, but unlikely, 60;40 luigi
