Sounds

I don't have too many non-Rattrap Beast Machines sounds so far, but more will come as soon as I can find more episodes on tape. 

Maximals

Optimus: "What's wrong Megatron? Is your single, elegant, machine having trouble multi-tasking?"
Blackarachnia: "Nice move, Spots."
Blackarachnia: "Whoah...you can teach an old ape new tricks."

Vehicons

Jetstorm: "Piece of cake."
Jetstorm: "Just don't hover there, get them!"
