|“||Dhaa! What an unhappy Halloween!||„|
|~ Memorella's final words before her destruction.|
Memorella is a mind-reading vampire-themed outlaw serving Sledge and is the primary antagonist of the Power Rangers Dino Charge Halloween special episode "The Ghostest With the Mostest".
She was assigned by Sledge to assist Curio and Duplicon into obtaining the Energems from the Rangers by infiltrating the Amber Beach Dinosaur Museum's Halloween party, with her likeness being so convincing that no one noticed she was actually an outlaw, though Kendall was suspicious.
When one of the Rangers is captured, due to the Rangers all dressing up as ghosts, Duplicon transformed Memorella into the duplicate of that Ranger. Thanks to Kendall's lie detector test and her own knowledge of the Rangers, she realized that Memorella was posing as Koda because he never uses formality with her.
Beaten by the real Blue Dino Charge Ranger, Memorella sheds her disguise, shape-shifts and flies away to escape. Upon catching up to Memorella, the Rangers fought her and the Vivix under her command. Using the Dino Cupid Charger, the Rangers make the Vivix fall in love with Memorella and then defeat her.
Sledge makes Memorella grow through the Magna Beam and in response, Ivan summons the Ptera Zord. Memorella is then destroyed once and for all by the newly-created Ptera Charge Megazord's Pachy Formation's Final Strike.
