Bee

Spiders. Are. Demons.

Sam

No sound. You always need noise, so when no noise is happening you're tapping your fingers. Without noise you get anxiety.

Optimus

Losing him.

Ratchet

blood. You pass out when you see it. Enough said.

Jazz

Hate. Jazz thinks you have a good voice and you should share it with the world. You don't want the hate, because you know you'll believe the comments.

Ironhide

Loud noises. It scares you, Ironhide learned that the hard way when he scared you will a confetti popper.

Megatron

Being forgotten. You're scared that if and when you die, Megatron will forget about you. Or squish you one day because he forgot you were walking with him.

Barricade

Actually, you're afraid of the night. Not the dark. The night. You don't like the fact that anything could happen.
