2. Alien X is seen as an instant win button especially after the popularity of Kuro's videos. Not bothering saving X for the climax may have raised eyebrows and having Hal pretty much break the reality wiping was probably seen as blasphemy.
3. Zoomers don't know shit about Hal. At best they grew up with John Stewart thanks to the DCAU or Guy Gardner thanks to Batman The Brave and the Bold
4. If Superman is Goku, Hal would probably be seen as Krillin to the unknowing public. They saw their god tier lose to a character they assumed would be Krillin level
5. Specifically on /co/ but this match up was Comics vs Cartoons and HEATfags like to gloat
6. Ending the match with scissors instead of an explosion because the people behind Death Battle wanted more creative finales
7. Ben Singer not wanting the episode to be too long led to shit like why the 6 thoughts crap was invalid not being expressed clear enough
