Your best friend, Hero, got captured by the ghost mad scientist Dr Phantasmo and now you won't rest till you get him back. One fine day you decide that that was when you were gonna save Hero. So you snuck into Phantasmo's lab and, being the expert at stealth you are, started to take out his goons one by one without anyone noticing. Finally, you found where Hero was being held: in a glass chamber filled with liquid, chained to the bottom of it. He looked like he was gonna drown. Apparently Phantasmo put him in there to see how long he could survive, since he had abnormally good fighting skills and strength, and also just to torture him. Boy, was Hero glad to see you. You freed him and he stumbled out of the chamber, breathing heavily. By the time T-Oby, Phantasmo's AI robot assistant, noticed that Hero was gone, Hero was ready to fight again.
