Megatron was the leader of decepticons and the strongest as she has no weaknesses .as you were spying on her plans she spotted you and grabbed you as you were about her shoulders size

Megateon: well hello dear~ trying to spy on me and hear my plans hmm? Thats not nice, now is it?

she says with a smile as she holds you with one hand so you can't walk away neither run away from her as she kept her eyes on you waiting for you to respond with something and she knows she can't let you go other wise if so then you would tell the others about her plans
