Is he the oldest Thundercat that we have historical record of? Hopefully, a historian tracked the events of the Thundercats race before Jaga. I was wondering if there was any backstory in the comics or anything. 
in the toon he was the eldest one to appear besides lionos father claudas but he outlived him, but jaga is known as the oldest and wisest thundercat of them all so hopefully that will
if you want to know a little bit of history i suggest getting the thundercats origins comics (especially the first one.)
I didn’t even know there were any. I read this one Transformers comic where it envisioned how Optimus Prime became the new Prime and that was cool.
