Any episode where Chakotay is the protagonist
What?! Hell no... Maybe in the last couple of seasons, but early on? One of the biggest travesties of Voyager was how when Seven of Nine became a regular cast member, they just kinda stopped giving Chakotay anything to do which made Beltran kinda out act and stop giving a shit.
The one where he's stuck in his own mind communicating with some aliens via a mental boxing match was really good. The character himself was awesome. It truly is a shame the writers/producers just didn't care as much as having more eye candy on screen.
