Heat Armor is a signature technique used by Nuova Shenron.
When performed, the user raises their temperature to a point where their body starts to glow a bright reddish orange, functioning as energy shield that can also harm an attacking opponent. The power is so immense that it is past the hotness of the Sun, around the temperature of a lightning bolt. It easily harmed Goku in his Super Saiyan 4 form. Omega Shenron is also able to use this technique after absorbing the seven Dragon Balls, specifically due to Nuova Shenron's Four-Star Dragon Ball.
- Absolute Zero - Eis Shenron's technique where he abruptly lowers his body temperature to below freezing, making him so cold to the touch he can freeze any opponent that touches him. Basically it is Eis Shenron's alternate version of the technique that works in an opposite manner, as the user lowers their body temperature to freeze instead of raising it to burn.
