Seismo is a Cragsters Mixel.


A shy, almost nervous Mixel. If Seismo gets restless, he might tap his feet and then there will be trouble. He has huge feet that are used to cause earthquakes that break through the rock layers. Seismo belongs to the tribe of the Cragsters and lives in a vast array of tunnels and caverns.


Seismo is a gentle giant. One of the sweetest-natured Mixels, Seismo's personality is the exact opposite of his tough appearance. While he can still wallop Nixels with ease and is quick to say when he dislikes someone, deep down, he is just a shy and timid Mixel. Like the other Cragsters, he lacks intelligence, but he makes up for it through brute strength and a surprising cunning streak.

Physical Appearance

Seismo is mostly grey in color. He has a round disc-like body that also acts as his face. He has a large single eye in the center of his face, with a dark grey eyebrow-like covering on top of it. Two dark grey horns that are attached to grey connectors rests on top of that. He has two gold rectangular marks on his cheeks. Instead of a mouth, he has a dark grey mouthpiece that moves when he speaks. He has short grey arms with dark grey pincer hands. His legs are very long. His right leg is gold on top and grey on the bottom, while his left leg is grey on the top and light grey on the bottom. His feet are very large. They are both grey, though the bottoms of them are various squares of grey, light grey, and gold.


His powerful feet can stomp down rapidly to burrow into the ground and cause earthquakes.


Early life

Little is know about Seismo's early life. However, he managed to gain a taste for Coconapples, making them his favorite food, at some point in the past.

First adventures

At a party, he managed to get kidnapped by the Nixels, and had to be rescued to help rescue the other Mixels. He was the first to be rescued by Flain. ("Calling All Mixels")

After struggling to get a Coconapple from a tree, Zorch ends up offering to help. Despite being nervous, he accepts the offer, and the two of them Mix. However, he burns his face, bowls over his brothers, and crashes into Flain's lava hot tub in the process. He states his dislike of Zorch, and is then knocked out by the falling Coconapple. ("Coconapple")

While enjoying Cookironis with the other Mixels, he realizes that Krader has the last one. It ends up trading hands multiple times, finally ending up with Zaptor. He and his brothers end up forming the Cragsters Max and give chase to him, but end up having to fight against the Electroids Max and Infernites Max. In the end, the Cookironi is broken, but they find a Nixel with a box to himself, and they all give chase. ("Cookironi")

During a Digging contest with his brothers, Krader managed to get lost in the Mountain City, so he and Shuff went to rescue him. After mistaking the Electroids' ritual for their Electroid Annual Dance Party as a sacrifice, they end up joining them, and Max to compete in a dance contest. ("Electrorock")

Seismo with his best friend Flain.

Flain invites him to the Magma Wastelands to ride on the lava slide, when they are ambushed by a Nixel swarm. They lose their Cubit in the process, but manage to retrive it and Mix, defeating the Nixels and upgrading the lava slide. ("Nixels")

A party that he was attending managed to be literally crashed by Flain and Krader. ("Murp")

Shuff ends up calling him to help stop Zorch so he can retrieve his Teddy Butterfly. Seismo's idea is to create a boulder wall to stop him, but the efforts end up futile. Eventually, all three Cragsters Max and turn into a boulder to roll over Zorch, stopping him for good. ("Mailman")

He and Zaptor Mixed together after stowing away in a Nixel's backpack to retrieve a Cubit that was stolen for Major Nixel, and zap him in the process. ("Another Nixel")

During a game of Rockball with his brothers, Flain ended up joining in. Working with Shuff, they launched the rock at him, which ended up catching on fire, catching the two of them in an explosion, yet also creating the game Mixelball. He ended up Mixing with Vulk to compete. ("Rockball")

He was an invitee to Balk's birthday party. ("Elevator")

Further adventures

During the annual Mix Festival, he ended up Nixed by the Mega Nixel Mixel Nixer, but was eventually turned back to normal. ("Epic Comedy Adventure")
