We found him like this

Karn was sitting in a healing chamber. " it says that he killed his own partner in a fit of rage " A scientist said.
" I'm going to find Jasmine and kill her once and for all " Karn thought to himself.
He got out of the chamber and put his Saiyan armor on. He walked through the hallways and saw a familiar man, Cui. " Looks like somebody had his butt handed to him " Cui said.
Karn kept walking to the space pod. And he flew to wherever his enemy awaited him.

Two of Freiza's men came towards them and destroyed there ship. They started shooting from their blasters at a rapid rate. " Hey isn't that Jeice's kid-" One of the soldiers asked before they were both kicked into the frozen pond, and finished of by a ki blast, by none other than Jayce.
They all found a cave to make their temporary home. A fleet of Lord Slugs men flew above the cave, there was still a handful of them. Most of the crew stayed in the cave and discussed battle strategies before attacking, Jayce and Jinx scouted ahead.

" Looks like your power level increased to, but I've trained a lot and have become even stronger than Vegeta " Cui stated.
" It's not just about strength, it's also about durability " Karn said and he put his finger in the air.
" Stop this right now! You don't know what your- " Cui was cut off by all the giant red spheres in the air, they all flew into him.
He could feel his body fall apart, and then a giant explosion followed. The red light engrossed the sky.
