Here is how testing the power he holds goes in Ryan F-Freeman's Adventures of Transformers: Prime.
[Apocalypse and his new followers appear on a hill top]
Apocalypse: Destroy what you want, child. Show us, what you are capable of.
Dark Nighlock: With pleasure.[walks into the Nevada military base]
Ryan F-Freeman: Nigh! Stop!
Dark Nighlock:[pins him against the ground with his telekinesis]
[he then starts destroying the base and disintegrating the soldiers who dared to stand against him, and the ones running away]
[Ryan struggles and grabs Apocalypse's leg absorbing his powers]
Ryan F-Freeman: Hello.
Ozai:[kicks him in the face]
Kylo Ren:[flys him up into the air, then drops him]
Ryan F-Freeman: [activates his jetpack] That's close. Who are you?
Kylo Ren: I thought you would recognize me without my mask.
Ryan F-Freeman:[shrugs in confusion] I meant the blue guy.
Apocalypse: I am En Sabah Nur. I am Apocalypse.
[we then see all the soldiers running, but some are disentegrated, while others are killed with their own weapons and artillery]
Ryan F-Freeman: Names, Ryan. Friend to the Autobots. Ryvine is afraid that he and Kylo Ren will never be as powerful as Darth Vader.
Dark Nighlock:[holds out his hand and looks as if he is trying to telekinetically tear out Ryan's heart]
Flash Fire: That is truly brutal.
Ryan F-Freeman: Not that they are brave to be strong like Darth Vader.
Dark Nighlock: [sighs and puts his hand down]
Ryan F-Freeman: Look. Here's the deal. You spare me and you can teach me your powers.
Dark Nighlock: No can do. Morins like them[in Iron Man's voice] killed my mom.[telekinetically slams him against a tree then completes the destruction just as the Decepticons arrived]
Evil Ryan: Whoa.
Ryan F-Freeman: Evil me.
Apocalypse: This is only the beginning my child.[teleports himself and his Horsemen away]
Ryan F-Freeman: Evil me... warn the Autobots.
