YMMV / Supergirl: Cosmic Adventures in the 8th Grade

• Complete Monster: Mr. Mxyzptlk—without the honor from his usual characterization—is an imp from the Fifth Dimension that plans to use Kara Zor-El's emotions to fuel a machine that would turn him into "the most powerful being in all creation". Initially disguised as the principal of Supergirl's school with other imps as the teachers, Mxyzptlk betrays his allies by draining their energy after deciding to use Supergirl's Evil Counterpart instead of her. Starting to collapse reality—including his own dimension—Mr. Mxyzptlk gloats to Kara and Lena Luthor about how his plan would destroy the Third Dimension and implies that he personally destroyed Krypton to manipulate Kara's life. Gaining control over the entire creation, Mr. Mxyzptlk treats it as his toy, wanting to "shake it" as his first action. Defeated by Supergirl, Mr. Mxyzptlk plots revenge on the entire Third Dimension before being judged and punished by other dimensional imps.
• Cult Classic: This is fondly remembered as one of the best Supergirl comics in the 21st Century. Despite that, DC chose not to greenlight its sequel series.
• Iron Woobie: Mr. Mxyzpltk tries to break Supergirl by taking her from her parents, attacking her friends, humiliating her in school... but he fails. And it annoys him.
  Mxy: See, in the end, you were just too sweet, just too optimistic and happy. I take you from home, I give you a best friend and make her hate. Nope. No matter what I put you through, you always looked on the bright side. Bah!
