Wheeljack, noun: A small but powerful destructive force to be regarded with caution.

"Wheeljack!"

Wheeljack turned with feigned innocence, wearing his best "who, me?" expression. "Yes, Prowl?"

"Why is the entire Ark suddenly filled with smoke?"

"Oh, that… ah, don't worry about it, Prowl! I'll have it cleaned up in no time!"

Prowl raised an optic ridge, one servo on his hip. "You aren't getting off that easily, Wheeljack. Clean up this mess, and then come see me."

Hanging his head, Wheeljack nodded nervously. Prowl then turned on his heel and walked away, leaving the unfortunate, but still pleased, scientist behind. This experiment had been a complete success! He now finally knew what had gone wrong with his teleportation device, and with only a few minor adjustments, it would soon be ready. Happy, he got to work.

Wheeljack, verb: To unintentionally create a high-power bomb.

"Ah, there you are, Wheeljack. Please, come in." Prowl said without looking up from his papers. Wheeljack nodded and entered, shutting the door behind himself.

"Prowl!" He said excitedly, holding up a small mechanical device. "I've finished it!"

Prowl looked up, frowning – a small but rare display of emotion. "Finished what?"

"My new invention! It's a teleportation device – here, I'll show you!"

"Don't--!"

The next thing heard was a loud explosion, and then the sound of a door opening and Wheeljack being shoved into the hall.

Wheeljack, adverb: To do something unexpectedly.

The next time Prowl saw Wheeljack, the inventor washing the grime leftover in his lab. It was already remarkably clean compared to the mess left after the explosion.

"Well done so far." He commented.

"Thanks," Wheeljack said, turning. "And guess what! I finished it!"

Wheeljack reached for the switch and Prowl braced himself, but to his surprise, there was no explosion – nor was there a Wheeljack standing before him.

He felt a hand on his shoulder, and couldn't suppress a smile.

Wheeljack, adjective: Something unintentional and spontaneous; Something not easily solved.

Wheeljack had been messing with his new invention for a long while now, and had encountered a very annoying glitch – it really didn't go where you wanted it to very often at all.

This time in particular, he had set the co-ordinates, flipped the switch, and looked around, finding himself in a small room that was seemingly empty. Seemingly, of course, as suddenly he noticed movement, a certain Seeker jet standing and staring.

"How did you get in here, Autobot?" Starscream asked, before grinning. "Doesn't matter."

Starscream approached, and Wheeljack yelped, fumbling with the controls. His control over his own body seemed to have deserted him, but he finally flipped the switch, and this time found himself in another, much larger room, with a tall white mech standing before him. Megatron blinked once, his optics powering off and on again, before he stood tall and towered over the other Cybertronian.

"You!"

Shit.

He flipped the switch again.

This might just take awhile…
