Storm and Magneto go good together for setting up DHCs. Have storm do a S. lk mk hk jump lp lk lp lk lightning attack lightning storm, and DHC into magnetic beam. If this works, things die. Immediately.
For those who got a bit confused...
S. = Standing.
lk = Light kick.
mk = Medium kick.
hk = Hard kick.
lp = Light punch.
mp = Medium punch.
hp = Hard punch.
So, the combo would look like...
Standing Light kick, Medium kick, Hard kick (Enemy is launched from this attack.), Tap up to chase, Light punch, Light kick, Light punch, Light kick, Lightning attack, then end it with Lightning storm. Before the storm ends, input Magnetos Magnetic beam combo, and watch your opponet just EAT damage. I've seen this kill at 60% and higher. It's VERY nasty.
I use Cyclops though because he works better with storm. His anti-air assist sets up for Hailstorm and aerial raves into Lightning storm, which you can DHC with Cyclops into Mega optic blast for TONS of damage. Or, you can put Cyclops on point, do a lp mp combo (Just those two hits. The mp launches.), start a mega optic blast, and in the middle of it, DHC into storms Hailstorm. Hailstorm is the SAFEST hyper combo in the game because it has NO recovery time afterwords, so you can DHC into it and have nothing to worry about afterwords. Amazing.
