Why did Tankorr bring Phil Bond to Cybertron in the first place?
A. To make Megatron worry. Tankorr WAS going to set up Optimus and Megatron so that they would destroy each other, but due to the event in Episode 5 – A Day in the Life (of Jetstorm), he decided to throw Phil into the mix. It’s for this reason that the Diagnostic drone suggests to Megatron that they attack Phil on Earth. That way, a majority of Megatron’s forces are preoccupied, weakening Megatron to the point where they can be effective against Megatron. Then Tankorr can come in and take over. Doesn’t quite work out that way, though.
