Tech 10: Super-Star Spirit

"Not bad," Aeron chuckled, wiping a bit of blood off of his face. "But not good enough I didn't intend on running into you two here, but it's a good thing I did." He cracked his neck. "Now I can eliminate you before you become too much of a threat."
"Okay, seriously, who the heck are you?!" Nova demanded as she and Theo got to their feet.
"And why do you look like me?" Theo's eyes narrowed as he reached for the StarTrix dial. "Is this an "evil alternate timeline" situation?"
"Name's Aeron." Aeron smirked. "And, well, yes and no. I am evil, and I am technically an alternate timeline version of you right now, but I can't speak as to whether or not this AU you was evil before he died."
"What is that supposed to mean?!" Nova threw her arms up frustratedly. ""Before he died"?! What, are you some kind of evil ghost or something taking his corpse for a joyride?!"
"That's the gist of it." Aeron gave them a wide, shark-like grin. "Technically I'm an Ectonurite, though I guess we're basically ghosts by your standards."
"If you're just piloting a corpse, then that means we don't have to hold back." Theo pulled the lever on the back of the StarTrix, transforming into Move Along with an emerald flash. "Nova, ready to go all-out?"
"Am I ever not?" Nova grinned as she summoned a pair of clawed gauntlets and assumed an offensive stance.
"Aw, it's cute that you think you have a choice." Aeron said mockingly before snapping his fingers.
A massive, red-scaled snake-like dragon alien wrapped in black cloth suddenly appeared in a red flash of digitized particles identical to one of Theo's Projection Transformations. The draconic alien charged forward at a speed that seemed to defy the laws of physics, and it was only a quick Flash Step at the last second that allowed Move Along to dodge the attack. As soon as the dragon missed its target, however, a wormhole appeared in front of it, swallowing it whole and sending it out through another wormhole aimed directly at Move Along, who was forced to dodge it again.
With Move Along and the dragon alien stuck trying to outmaneuver each-other, Nova summoned a pair of rocket boots and launched herself into the air towards Aeron, raising her claws in preparation to strike. Aeron simply smirked and made his body intangible just long enough for Nova to pass through it as she attacked, resulting in her stumbling into an awkward landing on the other side.
"C'mon man, you can't be an evil ghost and an evil Omnitrix user!" Nova yelled frustratedly as she turned back around. "Pick a struggle!"
"Oh, I've already picked a struggle:" Aeron sneered at her. "Yours."
"That doesn't even make sense!"
"End of the line, Aeron!" Nova-4 said.
"We're not going to let you get away again." Theo-4 said pointedly before seeming to stop and think for a moment. "...So that's what that feels like."
"God damn it!" Theo-4 snapped, kicking at the ground where Aeron had just been. After a few moments of doing nothing but cursing under his breath, he let out a deep, frustrated sigh and turned to look at Theo. "Y'know, now I understand why you were so pissed off at me all the time."
"What?" Theo asked, confused. "Do I know you?"
"It's a long story."
