Thunderbubble Mizutsune are special individuals of Mizutsune with different unique coloration. Instead of having pink fin appendages with yellow markings throughout their bodies, Thunderbubble Mizutsune have neon blue fin appendages with yellow markings. Their scales are pale while most of them are tainted neon blue. Thunderbubble Mizutsune fur on their bodies are a neon blue color as well. Their yellow long claws have a blue tip on them. Also, Thunderbubble Mizutsune back fins are constantly glowing.
When in rage mode, Thunderbubble Mizutsune bodies will glow blue with electricity appearing on their fin appendages and their tails.
Thunderbubble Mizutsune are capable of doing anything their relatives can do. However, unlike them, these special species of Mizutsune have the Thunder Element. While attacking, Thunderbubble Mizutsune will sometimes have bubbles with electricity inside them. If touched by foes they will have Thunderblight on themselves, so the bubbles will become magnetic, they will track you until they touch a few things (the floor, a wall, the hunter).
Instead of shooting highly pressurized jets of water at foes, Thunderbubble Mizutsune will shoot lightning beams out of their mouths.
Thunderbubble Mizutsune are been seen inhabiting the Misty Peaks.
