Thought I’d quickly add my 2 cents on the easiest ways I’ve found to open someone up with Thor.
The easiest way by far is simply to charge up a Mighty Strike L along the ground, it’s safe on block and eats projectiles making it hard to punish. On connection there are a couple of ways to capitalize on it, the easiest way I’ve found is simply to launch them, you can proceed to combo them in the air, or, as I’ve taken to doing, launch, jump and Mighty Strike M under them for the cross-over, upon landing you can combo them (C. L, C. H xx Mighty Smash M works) or hit them with Mighty Hurricane. If you chose to mighty Hurricane you can catch the bounce with Mighty Smash M stopping the hard-knockdown allowing you to launch again.
Other common ways to open up with Thor -
Tri Dashing - Seriously don’t under-rate this, if your opponent thinks you’re going up and blocks high you can use the huge amount of active frames on your C . H to combo from low, you can also Kara-throw into Hurricane, while that’s a fair bit harder to do there isn’t much your opponent can do to counter in that situation.
The other easy way I’ve found to get in is J. Mighty Strike M. Simply on it’s own it’s very effective, if rather telegraphed, backed up by a beam assist it works wonders. Thor also has much better air normals, such as the huge amount of active frames on his j. S and the fact j. H is active all the way to the ground. On registering a hit with either of these, cancel into Mighty Strike M and combo. There are a couple of ways of doing this, for maximum damage I believe st. H xx mighty strike M, c. H, s is your best bet. A lot of the time I like to combo with c. M cancelled into Mighty Smash M. If for whatever reason your normal misses after the Mighty Strike M you should fire off a beam assist or lockdown assist, whatever you have, and Thor should be safe from being punished.
The only other thing I want to add in this particular post is the best way to follow up air combos.
The basic air-combo chain with Thor is M, M, H, S, even though he has an eight way air dash and fly, I haven’t found any real way to abuse this in the way you might on Magneto, you’re generally best sticking with a basic combo and smashing to the ground or TAC’ing into a character with better mobility. If you chose to hit them into the ground, you have a couple of options, you can follow up with a fully charged Mighty Smash H if they’re the right distance, this will allow you to launch into a potential reset with air Hurricane, or launch into a Super with J. Mighty Spark L xx Mighty Tornado. If they are right across the screen and it’s imperative you punish them, you can OTG with Mighty Thunder and DHC into a character that can deal huge damage from full screen, I like doing this with Dormammu for Chaotic Flame. If you manage to Smash them down into the corner and land in the corner, a good OTG assist is your best bet, you can really go into any combo you wish from that point but the standard combo I’ve been using is Purification (Dorm OTG) charged Mighty Strike H, charged Mighty Strike S, Mighty Spark M xx Mighty Tornado.
The best way to finish a Thor air BnB without smashing your target to the ground is simply to go M, M, H xx Mighty Spark M xx Mighty Tornado.
Anyway, I hope this helps, obviously there is more to the character than this but I feel this will aid the basic guide will allow someone to jump on Thor and go for it, the biggest thing about the way Thor plays is that he doesn’t rely on his Magic Series at all, it’s crap, it seriously is, you can chain two J. L together into a C. L, C. H xx Mighty Smash M with timing, but that’s the best you’ll accomplish with Thor normals. Thor isn’t terrible because of this as a lot of uneducated players believe, Thor relies on special cancels so get used to those DP motions, Thor’s specials chain into each other and his main hyper (Tornado) very well and hit like a ton of bricks, you can easily pull a meter neutral 800k with Thor and with 2 meter you’re looking at enough damage to kill any of the cast from full health, including the God of Thunder Himself.
