Palpatine

here we have... old man palps, he's a pretty classic villain dating back to the very first ink x classic. Although he was only mentioned once then later on he fought the heroes when the gacha army attacked. One thing to mention though is in one of the gacha wars dated back to 03/25/2022 palps actually for once helped the heroes fight the gacha for reasons unknown. 
Not too long after that he became one of the main villains who was actually somewhat powerful and can fight well as a duelist. However since then he did the same villain thing, attacking, raping, or just pissing the heroes off with his shenanigan's. 
During the rise of the empire however he managed to turn koby and classic against kale and the other heroes who were becoming shunned upon as they had committed many war crimes and were losing what little trust people still had in them. Palpatine was the only villain who almost managed to gain full control through the wrath of his army and sith lords like, dooku, vader, and later on his sith army. However kale fought back and proved that palps and his empire was one big propaganda effort and were actually evil scumbags. The rise of the empire is dated back to 04/28/2022
Even though palps had failed that it was pretty clear he had still corrupted koby with the dark side turning him against the heroes and causing ink (who koby was with at the time) to also join him and summon the villains to kill the heroes. In that horrific event palps actually succeeded as koby and ink, along with the other villains killed many of the heroes like james, angel, and many others who at the time were opposed to them. 05/11/2022 
Palps later on continued attacking the heroes and has fought pretty much every single one, he even tried manipulating the traveler when she first met koby into believing he was evil by telling her all the bad things he's committed. In that moment when koby and palps began their duel palps actually bested koby in a lightsaber duel something no villain had done before. 07/14/2022
palpatine continues to make plans to manipulate koby into joining the dark side/villains one of his recent ones was to permanently kill ganyu hoping that the raw despair koby would feel after 5 failed relationships would overtake him and make him become evil. However that plan failed too. 07/25/2022
Palpatine continues to be a widely used villain who unlike many of the other villains can be a smart and powerful, if he wasn't so cocky and hell bent on turning people to the dark side he'd actually be a way bigger problem for the heroes.
