If you're a Ben 10 Ultimate Alien watcher, you'll know that Pierce just got killed by the Forever Knights. I personally think this was NOT necessary. Man of Action shouldn't have to resort to killing any minor character to get a good plot. And Pierce was a fine example of a plumber; he held great promise for the show.
If you, too, think killing off Pierce was a bad idea, put this stamp on your favorites.
