Far too many anime series have useless side characters that fans hate and protagonists begrudgingly put with. Many people complain about how they're weak, how they harm the protagonists, or just, you know, serve no purpose at all. These usless sidekicks in anime, at their best, don't really do anything.
People can make some really great arguments as to why these characters served some purpose to the plot.

The side characters listed below are the ones that get the absolute worst complaints, and frankly, most of them deserve it.
