"I wonder if my magic has as great an effect it did back in Equestria.", Nightmare mused as she gazed at the moon. "Time to test it out." Nightmare focused her magic and tried to lower the moon. And to her surprise, she actually managed to keep the moon from lowering. "It appears my full power is slowly returning, but this form doesn't have the same power I possess in the dreamscape. But at least I know I can still access my magic. Now. Let's see if I can find any other powerful presences here." Nightmare scanned with her magic again, and found Sunset, Rainbow Dash, Inferno, Ace, and Ice. "It appears they all have some form of The Elements' power as well. To engage them all would be foolish. Especially if Burst were to join forces with them." Nightmare sighed. "It's not likely I'll find any promising minions. But it's worth trying another scan." Nightmare focused her magic, and found a powerful presence. However, this one felt...darker. "Interesting. Perhaps this warrants some investigation." Nightmare turned into a cloud of mist and traveled to the source.
The source of the dark presence...
'I'll never forget that humiliating defeat I suffered!', a shadow's thoughts swirled. 'So close! It was within my grasp! He was down to only 100 life points! And yet he managed to completely turn the tables!' As the shadow was fuming to himself, Nightmare had just arrived. 'Wait. What is this?' The shadow inched closer to Nightmare as she fully formed. 'I can sense great power from her. Who is this woman?'
"There's no need to hide. I can sense.", Nightmare called out. The swirl of shadow crept its way over to Nightmare. "There you are. You're quite the vengeful one aren't you?" The shadow tried to form a shape, but fell back into a formless swirl. "I believe I can help you with that problem. But if I do, you must do as I say. Are we clear?" The shadow seemed to try and nod. "Very well then." Nightmare focused her magic on the swirl of shadow. Slowly, it began to take the form of a man. As the shadow fully materialized, Sombra stood once again.
"Yes...YES! I have a body again!", Sombra said with a crazed grin before turning to Nightmare. "And it appears I have you to thank for it. So? Can I have the name of the beauty who's responsible?"
"I am Nightmare Moon. And I wish to bring eternal night to this world. And you are?"
"Sombra. Former duel champion. And I'd have ruled this world if it weren't for HIM. That little brat Burst Stream! Now, I can pursue my vengeance!"
"Funny you should mention him...", Nightmare began. "I can't let you hurt him."
"Heh. And what're you going to-" Sombra was cut-off when Nightmare got close to his face as her eyes became cat-like.
"Burst. IS. MINE. And if you touch him, I'll un-make you just as easy as I revived you."
Sombra scowled. "Fine. But what do you need me for?"
"Simple. I want you to keep an eye on Burst and his friends. You should still have the ability to become a shadow. That should let you move unnoticed."
"Perfect.", Sombra said with an evil grin. "I guess I'll get started now." Sombra turned into a shadow, and slithered off. Nightmare turned into her mist form, and returned to her temporary dwelling.
"I'd better keep a close eye on that one...", Nightmare said as she drifted off to sleep.
