Jax dropped into the bank through a vent, his suit preventing the robbers from seeing him. There were two men in total guarding the hostages, who were locked up in the vault. He ran up to one and knocked him out using a pressure point. By then, his stealth had worn off. The other man tried to call out to his accomplices, but Jax had him silent and out cold before he could. "Alright. Step two."
He walked to the vault door, which had been blown open but was now crudely barricaded. As soon as he got there, he pulled the wooden boards away and opened the door. A couple people were shocked, but he put a finger to his lips. Not now. He motioned to the vent, and they began their slow escape from the bank. As soon as everybody was away, he smiled, and waltzed to where the other criminals were. One yelled. "Oh shit, it's the Bat!" Then Jax emerged from the shadows.
"What? Disappointed?" The ones that had guns drew them. "I know, I know. Freeze." He activated his freezing gauntlets and within seconds, the closest robbers were frozen. However, that didn't stop the others, and they kept shooting. Bullets whizzed off ice and walls, and Jax drew his own guns and loosed off a couple of shots. Most made their mark, but there were still three robbers, and Jax was under heavy fire. Jax had an idea. He picked up a grenade from a robber's body, and when he was ready, pulled the pin. He threw it into the general vicinity of the robbers, and dove through a window.
Jax heard the boom, and felt the heat, but he still climbed the building nonetheless, and fled the scene. Once he arrived at his apartment, he turned on the news, and was surprised to find him being one of the main subjects. "Holy hell." He quickly made some ramen, put in a bowl, and sat down to watch the show.
