Kamen Rider x Boku no Hero Academia(Combine Fanfic)

Robot in Grease

Build use the Vacuum Arm to suck the small blades that Stain use. Then Build use the Lion Arm to create shockwave from a long distance.

Build(In mind): Damn! He's too fast!!

Stain: You're not bad, Build!

Stain throw a bunch of small knifes and two of it able to gaze Build's suit near the left shoulder.

Build(In mind): Crap! He found my suit' weakpoint!

Stain: But this is the end!

He slash Build's right forearm using the katana. The blood come out from the wound and dripping down to his hand. Stain lick the blood from the katana and Build fall to his knees.

Build: My body! It won't move!

Stain: Comparing to you and that green-haired boy, both of you are worthy to let alive. I have a duty to kill the other two.

Build: Stain! Fight me! Get away from them!

Midoriya: Iida-kun! Wait, stop!!

Before Stain can stab Iida, a red and blue flame were shoot at him making him jump backward.

Stain: One after another... There's so many people getting in my way today!

Two figures appear from the shadow. It was Todoroki and Seiryuu, already in his Cross-Charge form, are there.

Todoroki: Midoriya, you need to give more details in times like this.

Cross-Z: You made us late.

Iida: T-Todoroki-kun, Seiryuu-kun, you too?! Why are you here...?

Midoriya: And you're using your left side...

Todoroki: Why? That's my line. It took us few seconds to figure out what you meant since you just sent your location info.

Cross-Z: You're not really one that send that for no reason. We'll take care of that guy.

Todoroki quickly freeze the ground and create an ice slide to to move Native and Midoriya away from Stain.

Todoroki: You meant that you're in trouble and need help, right?

Cross-Z: Don't worry, the pros will be here in few minutes!

Stain(In mind): Someone's time will be up soon, huh?

Todoroki: We won't let you kill these guys, Hero Killer.

Cross-Z: You have to fight us!

Todoroki: Seiryuu, don't use you blue flame here.

Cross-Z: Why?!

Todoroki: Blue fire are much more hotter than normal ones. It has the ability to create explosian. The smoke from the explosiam could minimize our vision.

Cross-Z: When you said, I think you right. But I still have this.

Twin Breaker!

Midoriya: Todoroki-kun! Seiryuu-kun! Don't let that guy see your blood! I think that's the way he get us all!

Todoroki: So that's why he use blades. If I can keep my distance...

A small knife just gaze Todoroki's cheek.

Todoroki(In mind): Shoot!

Cross-Z: Todoroki!!

He shoot Stain with the Twin Breaker and keep his distance from him.

Stain: You're got some good friend, Ingenium!

Midoriya(In mind): Damn! Huh? I can move?

Tatsumaki(In mind): Izu can move his fingers. He can move!
