Simon is the leader of the Shyon pack, Snow Shoe is the second in command.

Simon is a mix of a forest vorox and a glenn which is a totally different species, this kind of mix should not exist. This is why he has a massive amount of health issues, often forcing Snow Shoe to take up the leadership of the pack while he recovers. Due to this the pack trusts Snow Shoe much more than their actual leader.

Lets be honest though, Simon isn't really the greatest leader out there anyway.
