Soulseer Mizutsune is similar in appearance to the more common Mizutsune, although often noticeably larger in size. The fur across its body and tail is paler. While in combat, it will coat its front claws and tail in a substance that colors them with a deeper reddish hue. Its claws are longer as well.
Most noticeable are the scars running across Soulseer Mizutsune's face, presumably sustained in battle with another monster or hunter. While rendered effectively blind, its left eye will open and glow with a blue flame when the monster is enraged.
Although blind, Soulseer Mizutsune is able to perceive its environment through its bubbles. While not enraged, it will move about an area, releasing bubbles that will expand outwards in a spiral pattern before disappearing. Until a hunter comes in contact with these bubbles, Soulseer Mizutsune will move and attack much slower than a normal Mizutsune. It may attack more unpredictably as well, given that it cannot see its targets.
If a hunter comes in contact with its bubbles, Soulseer Mizutsune will immediately become enraged. It will attack more quickly and aggressively. Instead of releasing bubbles of different size or color, Soulseer Mizutsune will launch blue bubbles that explode on contact. These bubbles can inflict fireblight. Soulseer Mizutsune will often attempt to chain its exploding bubbles into other attacks.
Throughout the hunt, Soulseer Mizutsune will coat its front claws or tail with dark red bubbles, similar to the red, attack-boosting bubbles that common Mizutsune are known to release. This coating will make the applied part more vulnerable to damage and easier for blademaster weapons to cut, but will also increase their damage output. In addition, if a hunter is struck by Soulseer Mizutsune's claws or tail while the dark red bubbles are applied, then the hunter will get an attack boost for a short duration.
Soulseer Mizutsune will occasionally rear back, then attack with a spiral, drill-like rush. It is also capable of launching itself straight into the air, then coming back down with a body slam. The latter often has little warning and deals significant damage. When enraged, Soulseer Mizutsune will almost always follow up its double claw strike with one of these two attacks.
Like Mizutsune, Soulseer Mizutsune are rather calm in nature until provoked. Usually, Soulseer Mizutsune spend most of their time sleeping.

- Severing Soulseer's tail prevents it from covering its tail in the reddish substance.
- Without hitting a foe with one of its bubbles, Soulseer Mizutsune can't see hunters too well.
- It is possible to avoid all of its bubbles through a whole quest.
- Soulseer Mizutsune will occasionally cover its front limbs and tail in a reddish substance, making its attacks stronger with those parts. However, this also makes those parts weaker to attacks by hunters.
