Even more choices

1. Kitten - The spoiled daughter of Killer Moth might seem like a odd if not bad choice at first glance, especially given at what's at stake with Fuse. But you remember a issue in the comic where she surprised everyone when she created various persona's to gain her father's attention. She showed she could make various gadgets, costumes, and plans in a matter of days. All this together mean she could either be a skilled thief and can steal other criminal's gadgets or maybe eyeball the gadgets to recreate them.

While she might be overwhelmed at the stakes and what your offering her. Perhaps using her greed and spoiled nature against her would win. While at the same time letting her know that you see the potential for greatness in her, and how she could be the villain her father wishes he was.

2. Nega Starfire - The evil clone created by Trigon during the events of The End. She could be a useful choice if you teleport her quickly enough. Though it would also be wise to make sure the ship retreats farther away from this multiverse section, since this action might draw Trigon's attention.

Anyway this move is gamble since Trigon might have made sure his creation's were loyal to him. But perhaps you could find a way to the technology you have to transfer that loyalty from Trigon to yourself.

Another option is taking a gamble and hoping Nega Starfire doesn't have any true loyalty to Trigon, and would be more interested in her own interest and goals.

1. Nya Nya - One of the ink villains created by Uehara Daizo using the captive Brushogun powers.

Yes she has programing that makes Daizo her master and where her loyalties lay. But perhaps there's some technology here that could change it so your who she's loyalty to. Another option is perhaps giving her more free will and sentience.

Also perhaps after some examination and experimentation you could find a way to create a whole series if not army of Nya Nya. Maybe even find a way so that they share a hive mind, hmm certainly worth considering at the very least.

Though as a catgirl she might be subject to the whims of both being a girl and being a cat. Just because you give orders, doesn't mean she'll obey them in the way you wanted or even at all.
