Peace Thunder (ピースサンダー Pīsu Sandā?) (called Sparkle Lightning in Glitter Force and Peace Flash in the Smile Warrior dub) is a basic finishing move that Cure Peace uses. To use it, Cure Peace needs to charge her Smile Pact with enough fighting spirit to make it glow and grant her the power to perform the attack. This move requires a lot of energy to perform, making Cure Peace feel exhausted after using it.
Peace Thunder is capable of successfully purifying Red- and possibly Yellow-Nosed Akanbe, but does not work against Blue-Nosed Akanbe.
Peace first charges up her Smile Pact with her fighting spirit, making it glow and granting her power. She then makes a peace sign high above her head, and lightning shoots down from the sky onto her hand. She then spins around with the lightning bolts circling her, concentrates the energy onto both hands in their peace signs, and projects the bolt at the enemy. While most of the time she gets startled when the lightning hits her fingers, she can sometimes take it without flinching, like in episode 19.
In episode 29, she uses Peace Thunder to electrify her bowling ball and electrocute the Akanbe pins.
In episode 38, young Cure Peace uses Peace Thunder. However, when the lightning shoots down to her fingers, she gets shocked to the point that she stops the attack and cries.
In episode 41, Peace uses a powered-up version of the attack, named Peace Thunder Hurricane (ピースサンダーハリケーン Pīsu Sandā Harikēn?), against a Hyper Akanbe. Peace makes a peace sign high above her head, and a lightning storm shoots down from the sky on to her hand. She then spins around with the lightning bolts circling her, concentrates the energy onto both hands in their peace signs and then projects the bolt at the enemy

- The lightning bolt which strikes down on Peace's hand seems to give her an electric shock.
- Normally, Cure Peace is startled by this, but in episode 19 and New Stage 2, as well as whenever she uses Peace Thunder Hurricane, she takes it better than usual.
- In episode 39, Yayoi becomes Cinderella's fairy godmother and uses her wand to cast a spell whose animation is similar to Peace Thunder.
