Aspheera (LEGO Ninjago)

Aspheera is a character from LEGO Ninjago TV series and the main antagonist of the Fire Chapter of the show's Season 11: Secrets of the Forbidden Spinjitzu, as well as a major antagonist of Season 15: Crystalized.

Why she deserves to be trapped in her tomb

 * 1) She is a rather unoriginal character, recycling many features from previous Ninjago villains:
 * 2) She is a Serpentine, just like Pythor. Even her design is unoriginal, as she looks too similar to a Hypnobrai.
 * 3) To be fair, she is a Hypnobrai but doesn’t share any characteristics that the other Hypnobrai have. The same goes to King Mambo and the other snakes from Wu's backstory.
 * 4) She stole an elemental power from at least one character, especially ninjas, just like Master Chen.
 * 5) She is a sorceress, just like Clouse.
 * 6) She met Wu in the past and still has a bone to pick with him, just like Morro and the Time Twins.
 * 7) Her motivation is questionable: she claims that she wants revenge on a "treacherous deceiver" who trapped her, until it's revealed that the "deceiver" is Wu, who taught her Spinjitzu, through not before she promised not to use it for evil, in exchange for releasing him. Aspheera later used her new skills to overthrow King Mambo V and attempt to conquer Ninjago, which led to Wu confronting and defeating her. For some reason, both she and the ninja hold Wu responsible for this, even though he never deceived Aspheera, and she broke her promise first; Wu wasn't to blame for her imprisonment either, since it was Mambo's decision, thus making Aspheera's rampage nothing but a tantrum that went too far.
 * 8) She is hard to be taken seriously due to how she keeps screaming "Revenge!" and over-reacting. Many other Ninjago villains managed to be more threatening than her while keeping a calm demeanor. She even said “Revenge” as her final word in her show (so far) NO WE ARE NOT KIDDING.
 * 9) It is never explained how she managed to steal Kai's powers, create Elemental Cobras and resurrect Pyro Vipers without any training.
 * 10) Her attack on Ninjago didn't lead to any long-lasting consequences, the biggest thing she accomplished was banishing Zane into the Never-Realm while aiming for Wu, thus kick-starting the Ice Chapter, after which she was not seen for 75 episodes.
 * 11) For some reason, she was locked in the prison for Cell One in the following next scene after Zane was banished into the Never-Realm, even if the main characters, including ninjas, Wu and P.I.X.A.L, did actually not defeated her in the climax of the Fire Chapter of Secrets of the Forbidden Spinjitzu.

Redeeming Qualities

 * 1) To be honest, its hard not to feel bad for her, as she was trapped for a thousand of years in her tomb, aware but unable to break free the entire time, and it could explain her insanity.
 * 2) Her voice acting is well done.
 * 3) Despite King Mambo throwing her in her cell (Wshdtbtiht #2), he wasn’t the one who defeated her. Wu did, since he defeated her and didn’t free her like she did to Wu and Garmadon, that would be why she felt betrayed in the first place.
 * 4) Her saying “REVENGE” repetitively could be funny (depending on who you ask).
 * 5) She is more tolerable in season 15: Crystalized as she competes against Wu as the Ninja steal back her staff, she makes origami snakes, Pythor making fun of her “revenge” stuff etc.
