After realizing how many villain arcs Joey has, I have compiled a ranking of them for my own amusement. I am leaving out Deathstroke (2014) because joining the League of Assassins isn't really portrayed as villainous there, and it's part of a larger scheme to not do that.

5. New Teen Titans - Wildebeest Arc

New Titans (1988) #76

The original Joey turns evil arc. He has a mullet (unrelated to being evil) that he cannot pull off, which is very sad for me personally. This starts the trend of Joey talking being a sign of him having turned evil. There is a cool reveal here, and Joey is an extremely threatening villain. I appreciated the switch from painting people to painting ominous skylines as an indicator of villainy. The justification for the turning evil is that he is possessed by the hostile spirits of Azarath which is wacky (they could not think of a better reason, I guess. Overall falls pretty flat for me. The angst afterwards from Slade and the other Titans is pretty good though.

4. Deathstroke (2011) - Family Possession

Deathstroke (2011) #19

This has manchild Joey which is not a win for me. His design is pretty ugly as well. I think killing off Adeline in this arc was a little ridiculous. The most interesting element is that he can possess multiple people at once, with some more advanced control of each person. However, he typically gets beefed up powers when turning evil, so this is not that important.

3. Teen Titans (2003) - Slade Possession/Joey Resurrection

Teen Titans (2003) #4

The reveal here is really fun I feel, even if I think Joey's motives don't make a lot of sense. I suppose living in Slade's head for long enough would drive anybody crazy... It's kind of fun that he beheads Wintergreen, although it is mostly sad. Kneecapping Bart was also a fascinating play. This arc extends for a while as he gets trapped inside Raven's soul self and then later Cyborg's... computer half?

2. Teen Titans (2003)/Titans (2008)/DC Universe Decisions - Presidential Candidate Assassination Attempts

DC Universe: Decisions #4

Despite this being really over the top, it has some fun moments. My personal favorite is when Joey has the other Titans basically playing Werewolf/Mafia trying to figure out who he's possessing (and then the mental fencing with Dick once Dick realizes it's him). This is unfortunately a "crazy" evil arc, in which Joey is hearing voices that tell him to kill. I think having this be a side effect of his powers is definitely a unique concept but the execution leaves much to be desired. DC also copped out of having any sort of political motive in their 2008 election comic DC Universe Decisions by making Joey just be compelled to try and kill presidential candidates, which was pretty sad. The conclusion is extremely wild and one of my favorite Joey moments.

1. Deathstroke (2016) - Defective Morality Chain

Deathstroke (2016) #49

This arc gets top marks for matching Joey's characterization in the comic and being a logical conclusion of a lengthy arc. While this is not really NTT Joey and is a pretty different character, his need to take responsibily for his family members and control them (and the world around him) makes this all make sense. He is extremely overpowered here and does turn blue. It's also good because it's an arc where he chooses to do the bad things without it being because he's possessed by ghosts or hallucinating. In my opinion, it helps make the comic's conclusion a lot stronger.
