GEAR FOURTH TRIVIA

• In this form, Luffy’s Busoshoku Haki takes the shape of tribal flames on his body. This is the only example of Busoshoku Haki forming a recognizable pattern.
• In the anime, while changing to this form, Luffy is seen with a red aura around him.
• In the anime, a silhouette of Luffy´s Devil Fruit, the Gomu Gomu no Mi, can be seen while his torso is being coated with Busoshoku Haki.

• Luffy being covered by Haki in almost all his body, except for the abdomen, chest and head and the Haki shadow trim around his eyes are similar to Dragon Ball series’ non-canon Super Saiyan 4 (instead of Haki, the Super Saiyan 4 is covered by hair). In addition, both forms are named after the number 4.
• Similarly to Gear 2nd, Gear 4th allows Luffy to use techniques that appear to be his own reimagining of Rokushiki abilities, his pseudo-flight bears a striking resemblance to Geppo, and Leo Bazooka is seemingly reminiscent of Rokuogan (with Gear 2nd allowing Luffy to move at a speed similar to Soru).
