Have you ever wondered why Imu insists that Ragnir, the ice-powered squirrel, and Loki, who wields Nidhogg’s lightning power, make the perfect team? It turns out that behind Eiichiro Oda’s storytelling lies a deep well of scientific knowledge!
Their connection isn’t random. Imu confirms the link between ice and lightning based on convincing natural phenomena.
1. The Scientific Link Between Ice and Lightning

Scientifically, lightning actually originates from ice particles inside storm clouds. Within these clouds, tiny ice crystals are blown upward by wind, while heavier ice chunks fall downward. When these collide and rub against each other intensely, static electricity builds up.
This process is similar to rubbing a balloon on your hair. The ice crystals rising carry a positive charge to the cloud’s top, while the falling ice carries a negative charge to the bottom. When the charge difference becomes extreme, nature releases a massive electrical discharge to balance it out, that is lightning. Without the friction between ice particles, clouds wouldn’t generate lightning.
2. Imu’s Confirmation in Chapter 1182

In chapter 1182, Imu emphasizes that Ragnir and Nidhogg are a perfect match because lightning is created through the collision of ice particles. This revelation shows how carefully Oda has studied physical phenomena to shape his characters’ powers. The combination of Ragnir’s ice abilities and Loki’s lightning is not just a battle tactic but a flawless chemical and physical reaction.
3. The Devastating Combo: Ragna Arrow Blast

Their synergy shines in their combined attack called Ragna Arrow Blast. In this move, Ragnir’s ice is charged with Loki’s lightning, transforming into electrified arrows with incredible piercing power.
Ragnir and Loki truly are a legendary duo since the era of the War Gods. Do you think any other pair could outclass these two?
