The Control Rc gas grenade, shortened to CRc gas, is an experimental CCG weapon built to cripple a ghoul's kagune. When its gas is breathed in, it attacks the airways, and any Rc cells brought active in that moment begin to fall apart.
Developed by the Commission of Counter Ghoul as an experimental device, the Control Rc gas grenade goes by the shorthand CRc gas. It marks an attempt to disable a ghoul's most dangerous asset, the kagune, through chemistry rather than brute force.
Setting off the grenade releases its gas, which irritates the respiratory tract and mucous membranes of anyone who breathes it. Should a ghoul call up its Rc cells at that instant, the substance disrupts the kagune and drives it to break apart. The effect has firm limits, though. Kakuja kagune shrug it off, most likely thanks to their mutated makeup, and the gas does nothing to blunt a ghoul's heightened strength and physical power.

Naruto vs Luffy with the twist nobody asked for: Luffy tickled Hinata on date night, and she kind of liked it. We break down the whole fight and commit to a winner....

There are no women on Namek. That isn't an oversight, it's the biology. Why we handed Piccolo the one thing his own species rules out, and why it had to be trap soul....
