These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Complete Monster: Annihilus becomes this. No longer content with ruling the Negative Zone, Annihilus leads an army of insect monsters out in the galaxy in what is aptly termed The Annihilation Wave, consuming whole star systems and devouring worlds. Implementing ghastly tactics like having worlds and their people broken down for fuel on board his Harvesters, Annihilus's attacks make the Skrulls an endangered species and cause the extinction of many other races. After brutally murdering the hero Quasar, Annihilus even succeeds in having Galactus captured and uses his energy to fuel his superweapons with which he has one goal: to obliterate everything that lives and reign over the void.
Ensemble Darkhorse: Drax the Destroyer before his mini series that lead into the event and his appearances was not nearly as popular or well known.
Mary Sue: Wraith in Annihilation: Conquest he wears all black, rides a (black) space motorcycle, fights with a (black) whip, and comes from a conveniently forgotten off shoot of the Kree (who also wear all black) that are so hardcore that only pain is intense enough to make them feel anything because the (black) parasite that makes them immortal also eats their immortal souls. It gets better, the Phalanx (a race of emotionless robotic parasites) are afraid of him. Torture makes him laugh. It's like Marvel hired a emo 14-year-old to write for them.
