This will be fun. But first I want to apologize for answering this ask late. Anyway, onto the chaos.
If I was in Transformers Animated Part 13: The Elite Guard's "Visit"
(This takes place before Ultra Magnus gets his aft kicked by a twig)
Sentinel Prime: Sir. I don't want to seem rude but why are we checking up on Optimus on his crew?
Ultra Magnus: Because of recent events I have decided that seeing how Optimus and his crew are doing is important if they want to continue their duties on Earth.
Sentinel Prime: I just hope we wrap things up before Cat can do anything.
Jazz: Aw come on SP. Cat's fun and you have to admit they have been more than helpful to us.
Sentinel Prime: Helpful to you maybe. All they have done is cause trouble.
As the ship landed Sentinel was more than cautious in exiting the ship.
Jazz: Sentinel. Cat's not going to pull anything this early.
Sentinel: Yeah? Well, why don't you tell that to the deca-cycle it took just to wash out all that glitter from their last prank. I swear I can still see some specks around the ship.
Sentinel: Speak of the devil.
Optimus: Ultra Magnus. What brings you here sir?
Ultra Magus: I have come to see how you and your crew are doing, given recent events.
Optimus: Oh. That is very compassionate of you sir. Um. Cat? If you are up for it can you accompany Jazz and Sentinel on patrol?
Sentinel Prime: What!? Sir. I think we are better off staying here.
Ultra Magnus: I think you and Jazz going on patrol is a good idea. It can give me time to talk to Optimus alone.
Me: Ok. Let me grab my bag real quick. And I call riding with Sentinel!
Jazz: Cat. Why do you want to ride with Sentinel?
Me: Well because I have realized that myself and Sentinel don't have the best of relationships.
Sentinel Prime: Got that right.
Me: But I am hoping that this patrol can help us grow closer as friends.
Sentinel Prime: If that day comes I'll eat my elite guard wings.
Me: Anyway. You remember the Headmaster guy right?
Sentinel Prime: Umm. I have never heard of him.
Jazz: Oh. I remember. Prowl told me that he stole Bulkhead's body. Why bring up him?
Me: Because I happen to know where he is staying. He's staying in a nice house thanks to Powell and I was wondering if you want to help me play a little prank on him.
Jazz: Oh? What do you have in mind?
When we got there I had pulled out a few rolls of toilet paper and a few round grey balls.
Sentinel Prime: What are we going to do with those?
Me: Well, we are going to cover his house in toilet paper and place a few of these around the outside of his house.
Me: Sentinel? Do you remember my last prank?
Me: These babies explode in a glittery mess.
Sentinel: I want to place them.
Me: Sure. You show me where and I place them.
With there help we got everything done pretty quick and were out of there before anyone had taken videos. Plus when we got back we had the joy of seeing the Headmaster freak out.
Sentinel Prime: Play it again!
Me: How many times have we seen this video.
Sentinel Prime: Don't know and don't care.
Jazz: You two seem like you are becoming good friends.
*Jazz then hands him a separate pair of elite guard wings.*
Sentinel Prime: Hey. I just enjoy seeing that human guy freak out there is no way I'll ever call Cat my friend. Now, I will see you later. Though send me a copy of that video ok?
*Sentinel then walks off and back to the ship.*
Jazz: Yeah. I'm sure he will.
Ultra Magnus had finished up by then and with that, they had to go back to Cybertron. Though not before I got one last prank in.
Sentinel Prime: OH COME ON!!
Jazz sped to Sentinel's quarters to see that Sentinel had found his desk to be covered in sticky notes that formed his chin. Jazz promptly started laughing his aft off. How Cat managed to do it they never found out but by then they had already left Earth's orbit so there was nothing he could do.
