Who's that Lurking in the Shadows

<SNIP>
Herbie ran towards the ship, once again he was in trouble. I mean its not like something like this has happened before is it. Well that is a lie.

'I can see her,' Herbie smiled.

'See who?' Jay asked running to Herbie's side.

'The ship, I can see her!' Herbie continued to run, if only he was on the open waters surfing right now. Herbie hoped the cheap weaponry would come in handy.

'Good, keep on going!' the crew screamed.

Soon they had made it. The aquatic blue metal was submerged in the sand, still the windscreen wipers were wiping away as intended. Herbie climbed to the back and pulled open the airlock. 'Come on then!' Herbie whined.
Inside it was dark and cold, but they were not alone. Someone had made it in!

As the crew entered many they felt a pain that could resemble eating one of Phil's Kababs. As several crew members dropped to their knees puking and pooping themselves uncontrollably, Jaxx lit the room up with his holowhips. The glowing blue light holowhips revealed someone in the shadows with some kind of baton hitting the crew members in the back. Jaxx quickly said in his Darth Vader voice, "Stand back Eve babe this dude is most wicked." Evelina took a step back from Jaxx and tripped onto a wall. Then as Evelina tried to regain her balance she accidentally flipped on the emergency lights. The red lights revealed what Jaxx was seeing. A man in a black outfit with some kind of high tech baton dropped several members to the ground and caused them to puke and poop themselves. Jaxx said in his Darth Vader voice, "Not cool bro! Your cleaning up this mes.....!" Just then the attacker tried to hit Jaxx with the baton only to have Jaxx catch it with his claw head. As the attacker realized it had no effect on him he panicked. Jaxx quickly wrapped his holowhips around the attacker and made him scream till he passed out from the pain.

Jaxx then turned to Evelina who was trying not to puke by the smell of the room, but flattered by Jaxx's concern for her. Jaxx looked around and said, "Hey Eve babe help me get these sickly dudes and dudettes outside. Then I'll totally grab some gear after that." Evelina nodded so she wouldn't have to breath the nasty smell in the ship. After everyone was removed from the ship Jaxx gave Evelina the baton the attacker was using so she could keep guard over him. Then Jaxx went to check on Jay to see what he wanted to do next.

TAG
(The baton is a Sick Stick. It causes a victim to puke and poop themselves violently)
Who is the attacker and what does he want?
