Storm would have to be the second hardest match-up (Cable is first) for Colossus. She has supreme mobitily that makes it tough but not impossible to land a hit on her, and also she has alot of “beams” that give colossus a hard time.
Here a few tips and strategies I came up with to help against the “weather witch”.
*Don’t use random shoulder charges or Hyper Armor when you know they’re not going to hit. Even using the instant recover shoulder charges Storm can still manage to punish Colossus.
*Only use your HA when Storm is super jumping or after a hit from a shoulder charge. Storm’s typhoon’s and Hail Storms are considered beams so they pierce his HA and do normal damage even with his armor. So you don’t want to throw out his armor and get hit with those during his 3 second power up phase.
*I normally wouldn’t recommend using HA alot against her, because you won’t see her again until its over. While she’s running away be sure to build up meter yourself by using sj.FPs’. Just watch for typhoons and HSs.
*Keep is simple against her. Stick with your normal attacks especially the long range ones such as s.FP, d+FK, or j.f+FP. You’d be surprised how many s.FP you can land on your opponent since it catches them off guard alot and not very punishable. After 6 s.FP Storm will be dead.
*When Storm’s on the ground and they go for a typhoonxxHS, you can jump over the typhoon and land a f+FP before the HS goes off. I wouldn’t recommend trying this every time but as a last resort thing if she has 5 bars and tries to chip half your life away.
*Take advantage of her mistakes. Such as a missed lighting attack xxx LS. Stand right below her and hit here with a power dive. Storm doesn’t have alot punishable mistakes, so you gotta besure to hit when she does.
*I’ve never tried this but someone told me it could be done. If you’re at sj height and you see her going for a hail storm you can power dive up out of the screen where the HS can’t hit you and come down just after and land a hit on her before she recovers. It sounds like a great idea but I don’t think it will work. I never had the guts to try it but if someone does confirm it works please let me know.
I hope this few tips will help out anyone that has a problem against storm. Feel free to expand and add anymore info you may have.
