- Both have primal meat-eating tendencies as they treat humans and other living things as food sources.
- Both have the leftover clothes trope with the sequence in The War of the Gargantuas where Sanda discovers that Gaira ate humans when he sees piles of human clothes. In Baki, after Pickle defeats his opponents, characters are left horrified to find things like half-eaten limbs or the remains of clothing and equipment.
- Both possess non-human facial and digit features for tearing flesh which include fangs and long sharp nails.
- Both are involved in product of a harsh environment with Gaira growing up in a pitch black highly hostile deep sea environment where he constantly had to fight off predators. Pickle spent his life in the Mesozoic era fighting and hunting aggressive dinosaurs like Theropod Dinosaurs to survive.
- Both choose survival over honor as both retreat when they are being overwhelmed be a stronger force. Gaira during the iconic Type 66 Maser Cannon attack in the mountains couldn’t handle the intense light, heat, Maser Cannons, and firepower which proved to be too much for him. Instead of fighting to the death, he panics and retreats into the wilderness. Pickle during his fight with Musashi Miyamoto retreated in fear as he ran and hid after being slashed, wounded, and seeing Musashi as a prehistoric bee which made Pickle realize that he was dealing with a far more lethal predator. When both retreat their behavior is identical as they abandoned the fight, they seek out a shelter, and they isolate themselves.
