Red sun grenade

Red sun grenades are devices that emit radiation that mimic Krypton's red sun. They are similar to Yellow sun grenades but instead of gifting Kryptonians with temporary powers on a world with a red sun, it is designed to take away a Kryptonian's powers temporarily on a world with a yellow sun. The D.E.O. attempted to use them against Reign but she remained unaffected by them as her powers are not negated by a red sun due to her powers not coming from solar rays.
