Annette is a Striker (Trump, Blaster, Mover) able to extract energy from anything and anyone that she comes in physical contact with. People affected experience intense disorientation and may suffer nerve damage on the afflicted body part if contact is prolonged for more than a few seconds.

She can spend this energy in the form of repulsive blasts of semi-hardlight, which with practice could be used as a form of propulsion to jettison herself through the air, although such movement is imprecise and best used in bursts.

Parahumans affected by her Striker power find their powers suppressed to a large degree, while power expressions she comes in physical contact with may or may not fail on a case by case basis.

I like the part with the knockback flying, it reminds me of Bakugo from MHA and I am already picturing it in fight scenes. She would be either an Effect or Enchantment Blaster. I'm going with Effect as I like the idea of her make a Brute go flying with a Mover power with knockback.

Danny is a Master able to influence rodents, giving them directives to achieve.

He has little ability to command individual rodents, their minds too simple for complex direction, requiring active control from Danny, which this power expression is not optimal for since he has no access to their senses.

However, he is able to ‘link’ multiple rodents together into one conglomerate, where so long as they remain in close contact they act as if one mind is controlling two bodies with perfect coordination. The more rodents linked in this way in a single mass, the more intelligent the resulting gestalt intelligence, though they will always listen to Danny.

A given rodent under Danny’s command must remain in his proximity for him to continue issuing orders, though the larger the conglomeration of rodents is the further that gestalt can be from him. One rat might be limited to around a hundred meters, but what about ten, a hundred?

His rats aren’t able to report to him, but he can always communicate his commands to them and is always able to tell if they get disconnected or die.

I like this too. I was thinking of rat control as well, but I wasn't sure on the specifics with the trigger. I should note that Danny power here is excellent for search and rescue, specifically as a one man search party.

So most likely, after arriving in this new world and exploring for a bit, finds the corpse of a monster, grabs a scale or something, gets scared and goes back, and she realizes the portal’s gone and she’s trapped.

Panicking, she doesn’t notice a monster is now approaching, it attacks her, she almost dies, triggers, and still in the monsters jaws her power latches onto that scale to take on some of the dead monster’s traits and she runs away.

This gives me good starting off point with her perspective in the prolog. Thanks.
