In the end, it'd amount to the same thing - at least given the way Megatron would be teaching it, and what he would be teaching, but if it made it easier for Orion to swallow, that was all that was needed to justify phrasing it as "self-defense" instead of "combat training".

Engine revving briefly and a slight twitch running through him at the pinch, Megatron chuckled and then gave Orion an arch stare.

"Oh, I promise I'll be gentle, Orion." And really, if need be, he'd be as careful and slow (and gentle) as was necessary to let Orion learn and then slowly step things up, but he didn't think he'd need to go to extreme lengths. Despite that, he grinned sharply again as he spoke.
