The connection between Underbite and Grimlock

Underbite and Grimlock seems to know each other for long. I already made a video about that but I have some more ideas about their connection. 

So they're both prisoners aboard the Alchemor. But I don't think that's how they have met. Grimlock seems to know Underbite before they were in the Alchemor. Apparently,they were childhood friends before the war when they were younger. They used to play together. The war is what separated them and because of some manipulation,Underbite turned against Grimlock. It won't be long until Underbite became power hungry and Grimlock see him eating Nuon City. However,he didn't let anyone know about it because he didn't want Underbite to get into trouble. But a cop notice it and arrest Underbite for eating a city. At first,they tried to treat him with some possible treatment for his condition. When that didn't work,they had to unfortunately put him in a stasis pod aboard the Alchemor,hoping it would stop him from eating. Grimlock was'nt too happy about the situation and started a rampage,which leaded him to be arrested and put in a stasis pod aboard the Alchemor alongside Underbite. When the ship crashed on Earth,Underbite's stasis pod was broken,thus freeing him and escape in search of eating something. Meanwhile,Grimlock's memory core was damaged in the process. That's why he don't remember what he has done to be put in the Alchemor. When the two has finally met up again,Grimlock's only desire was to fight. Although they still remember being friends and ended up in the Alchemor together,they still became enemies due to the war from long ago. Maybe by the end of the series,they succeed to treat Underbite's condition.
