He makes an epic entrance!

"Lunar... Smash!" Izuku shouted as he suddenly came flying in, both legs extended, having named this attack with both All Might and Mirko in mind. He knew he was announcing his presence by doing so, but if he didn't, Stain would take the hit, but his blade would hit Bakugo at the same time, so Izuku was trying to get him to dodge instead. It worked, and Stain jumped back, looking up at Izuku in irritation.

Izuku landed, cracking the ground as he did. "Kaa-chan, you alright?!"

"Deku! Get the hell out of here! This bastard is mine!" Bakugo roared. Izuku ignored him, instead assessing the situation.

"...another fake to be?" Stain mused, watching Izuku closely. The experienced Villain noticed that Izuku was already looking for escape routes and was moving to grab Bakugo. Hmm, he seemed to have the sense to not come after him for the fame at least, he looked more inclined to take his apparent friend and run. He then noticed that Izuku paused as he saw Native, and his plans to just take Bakugo and go went out the window, since there was someone else to save. That piqued Stain's interest.

"...what the hell were you thinking, Kaa-chan?" Izuku sighed, preparing to fight, while reaching behind his back, sending his current location to the entire class. He wished he could send more details, but he hoped at least someone would get the message.

"Forget about me!" Native shouted to Izuku. "Just take the other one and run! I'm the one he's after! If he cuts you, you'll be paralyzed by his Quirk!" Izuku paused, wondering how it worked. Just the act of cutting, or something else?

"I said get out of here, Deku!" Bakugo snarled. "I'm going to be the one to stop Stain!"

"Shut up," Izuku snapped at Bakugo, deciding he had had enough of his crap. "You're clearly no match for him, and you do clearly need help... Just like that time with the sludge villain... Even with the odds stacked against me... I just can't abandon someone to die!" he declared, making Stain gaze at Izuku with interest. "A Hero... Is supposed to save people, no matter what!" He then charged Stain, who broke out into a vicious grin.

"Interesting... Let's see what you got then!"
