(I love this premise btw)

As Hellboy walked into the train station, he saw Beast and Storm talking to each other out of his ear shot.

"Oh come on, this job never stops." He said as he started running towards beast.

In an instant, beast was knocked to the ground, his air forced out of him. Storm turned to Hellboy, who just said "that's not who you think it is. Run." Before smashing a hole through the ground and dragging beast through it.

"Come here you demon." Hellboy shouted as beast tried to get to a safe place to talk.

"I don't know who you think I am, but I'm definitely not them. I'm no demon, I'm just a mutant." Beast said.

"Yeah yeah, sure you are bud." Hellboy said, grabbing Beast and punching him in the gut.

"Oof, ouch, that broke some ribs." Beast said through the pain.

"Get over it, you're going to hell anyways." Hellboy said, his arm poised back, ready to strike, but right as he is about to punch, he is knocked back by a massive gust of wind provided by storm. "He us not who you think, this is beast, a human that looks like an animal because of his mutant abilities . " Storm patiently explained.

"Alright, but if he bites your head off while you sleep, don't say I didn't warn you." Hellboy said before walking off.
