Time Keeper, Handsome Jack and Calypso Twins
I finishend another Run of borderlands 4 and it caused me to come to two conclusions being one the new vault hunters are more compassionate then the last groups and that no one can top handsome jack as a villain. the first one is a whole different discussion.
The Calypso twins were lack luster but i did enjoy them, and after the second Tales game with how they massacred my boy Rhys i had low hopes for 4 but the Time keeper was a great villain while things could have been done better or differently i was extremely happy with it which brings me to handsome jack.
Handsome jack simply cant be beat he was simply too good so when people kept saying that borderlands in terms of it villains will never make a villain as good as Jack simply don't understand. Jack in terms of story and as a Villain is the peak of Borderlands, we can be on Borderlands 8, gear box can write a perfect story and perfect Villain and they would still be second fiddle to Jack. Gearbox set the bar so HIGH with Jack that even if they fix everyone of their problems they have in their gameplay, story and villains people would still complain it wasn't as good as 2 and Jack.
