The Transformers VS Apokolips

All Autobots and Decepticons, working together perfectly (no fighting each other, no treachery, etc), invade Apokolips with the intent of deposing Darkseid. They are lead by Optimus and Megatron.

1st scenario: 10 days of prep time for the Transformers and 10 for Darkseid and Apokolips
2nd scenario: No prep time.

1st scenario: 80s cartoon Transformers.
2nd scenario: 80s Marvel Comics Transformers

Edit: Forgot to mention, a Mother Box resizes the Transformers to make them the same size to New Gods when in the NGs' dimension as TFs are to humans when in Earth's dimension.

Darkseid looks out the window sighs and teleports them all into a black hole.

All Autobots and Decepticons??? Unicron would have to be excluded from this battle.

If somehow Darkseid didn't know they were coming, I think the Transformers could pull it off.

Well........if we're talking about the cast of the cartoon, let's say, that has a definitive limit in numbers. They aren't as numerous as the entire Transformers line, and I think that the forces of Darkseid should easily be able to take them apart....literally.

Apololips
If a single no name like Maelstorm can own Supergirl a whole planet of them would destroy the Transformers in seconds
