Megatron being really good with sparklings is just the cutest headcanon because it makes me think of all the sparklings that trailbreakerofficial and londonprophecy created going missing on the Lost Light one day and everyone is freaking out looking for them and having sparkattacks.
But then they check the bridge last and there are the sparklings all curled up on Megatron during one of his grandpa naps. Because he’s warm and they like the deep rumbling sounds (snoring) he makes.
Oh my gosh that’s cute. Those poor parents though.
