I was just wondering, what if Zach Varmitech had an older brother, who overtime becomes an ally or even friend to the Wild Kratts?

I was thinking he would disconnect himself from Zach because he got fed up with trying to keep his little brothers antics under control from early on (before the show premiered), and so would mean they haven’t had much of a good relationship during their lives.

He would be this seemingly tough hermit guy (though still young, around the Wild Kratts team’s ages or a little more), though has this secret love for all animals, which he learns to express more when he spends more time with the WK’s.

Also, perhaps he could even have a close relationship with Aviva, after some time with her being a little untrusting to him (since her interaction with the other Varmitech brother isn’t very good), but eventually comes to trust and care about him. Perhaps there could even be an attraction to one another

For another animated character I can think of as a comparison, I would think Beau Neville from one of the old Scooby Doo on Zombie Island movie, and his featured relationship with Velma from it

This is just a rough idea I was thinking lately, what do you all think?
