Considering I main both characters and I play them both 50/50 it depends on what you do.
As Riptor you wanna keep fulgore as close as possible to you at all times. Use your tail for hard knock downs and lay down flame carpets or spit fireballs into the air to rain down on him. Keep in mind that you will have to mix up your attacks and pokes as well. Since I’m sure not all Fulgore players are gonna fall for the same thing.If you have combos going you can use your tail-flip ender to achieve this.
Just remember that if you have Fulgore down you have the keep the following in mind:
1- If you have Fulgore with hard knockdown. Anything that invovles using your tail: Lay down a flame carpet or spit fireballs. But do not attack after. Don’t jump in the air, don’t do tail flips. Don’t do ANYTHING that leaves you open to a cyber uppercut. If Fulgore tries anything but cyber uppercut he’ll be hit by the flames. If you throw a fireball into the air Fulgore’s cyber-uppercut gets stuffed. Or! if there’s a situation where you do lay down a flame carpet and he does a cyber uppercut, block it and use clever girl to pull him into a ground bounce.
2-If Fulgore is not on the floor from a ahrd knock down. If you’re close just brace for a wake up attack staying just outside of grab range helps to. And be careful of a wake up grab. In general a wake up attack is all that’s need to put Riptor at a possible disadvantage. But that’s an issue for her against the whole cast. So keep that in mind.
Clever girl may not look much but if you have someone trying to jump you can yank them back into a ground bounce. You can flip-em out etc.
Basically you don’t want to give Fulgore ANY room. If you’re using a rush down character. If you give Fulgore any room to breath he’ll be able to set you up. Fight Fulgore not like Glacius, and not like Jago, fight like you’re battling both at the same time.
Fulgore may have fireballs, lasers, teleporting etc. But they don’t mean ■■■■ if Riptor is too close to hit him before he gets a chance. Just don’t do anything that leaves you at a disadvantage.
I admit I beat my bro regularly as Fulgore when he’s RIpotr. But that’s only because he’s played as her in the MU so many times and add that I also main and know Riptor really well leaves him at a disadvantage.
Stay close, and don’t do anything stupid.
If you haven’t been trying any of what I suggested above, you are likely not doing so well against Fulgore. This is a hunch however.
