In most Superman mythos, because blue stars emit more energy than both yellow and red stars, Kryptonians exposed to their radiation receive an exponential power increase.
Livewire and Psi both call Imra "Matilda", a reference to the movie Matilda (1996) where a young girl displays great intelligence and telekinetic powers.
The name "Live Wire" was an alternate code name of the Legionnaire "Lightning Lad", who in the comics is married to Imra (Saturn Girl).
Livewire references the last time she saw Winn was in Livewire (2015) and Mon-El in We Can Be Heroes (2017).
