Max: STOP GOING THREW MY CLOSET!!
Tech: But there's so many interesting things in there.
Wolf: Maybe you should calm down a little ^-^"

Chaz: STOP CALLING ME TEDDY BEAR!!!
Teper: Why? Your big and soft like one.
Ricky: Baka. Why would you get mad about something like that?

The big hot headed brawlers, the "It looked interesting" always playful ones, and the neutral, peacekeepers. I guess it works for Max, Wolf, and Tech since they are brothers, but I think Chaz and Teper would try to kill eachother, and Ricky being how he is would try and incompasitate both of them when they ignore him or call him just a kid.
