So this is the random idea I had yestoday, now I know that I not the first to turn TUGS characters into cats because there is a good quality fanfiction on here about some adventures they have as cats.
So I'm guessing there might be a few questions raised from this profile. Here is my best explanation of it all:
He is apart of the Star Clan which just the Star Family (the name of the Star Fleet when they are not in their normal forms). He is the oldest son of Captain Star. If you're wondering where O.J comes into this family, well, he is Captain Star's father.
I had to change Herc's age a bit, in my human headcannon he is 24 years old in the show timeline but of course he is a bit younger in this version. I'm not very sure how this will effect the rest of the family (I don't think Sunny had joined the Star Family yet). As I'm not sure how many 'months' he would be.
I think it's just like the human version but they are just cats now. Even the ageing stays the see.
Also about the scar on his left eye, that is something I keep through out all the different versions of him. That scar come from back when he was still in the navy, it's either from accident he had or from fighting, I don't really know.
I think that's all. If you have any more question(s) feel free to ask.
