Vegeta was hardly anything like Raditz and the only comparison between Frieza and King Piccolo was a similar motivation. In either of those cases though the latter villain was drastically better.
He was a wrinkly old fossil who seeks and uses the Dragon Balls to regain his youth but even old kicked Gokus ass...just like King Piccolo.And I don't see how Moro is a pale imitation to any of those characters you just mentioned.
He travels to Namek with the desire of seeking the Dragon Balls and eventually destroys the planet and it's people...just like Frieza. He leads a bunch of minions as they travel throughout and terrorise the universe... just like Frieza. He heads to Earth where said minions fight the Z Fighter scrubs before fighting Goku and Vegeta.... just like Frieza.
He absorbs energy to become stronger...just like Cell.
He's a villain who destroyed countless planets, fought the Kai, was "stopped" by Grand Kai, was confined for millions of years before being released....just like Buu.
He's a powerful anthropomorphic animal that's been around for millions of years...just like Beerus.
He has just other better characters traits rolled into one boring package.
It would have been interesting 8 years ago. Now he's just yet another anthropomorphic animal from a series that gave a cat, a mouse, a fox, a elephant, a rabbit, a trio of dogs and a bear.I find Moro's design to be infinitely more interesting.
It's just the same thing again except this time it's a goat. He even looks worse now than before, when he was sporting the homeless bum look he at least somewhat different. Now he couldn't look more generic.
And what is so interesting about it? Like practically every other antagonist that has a crew beneath him, he doesn't give the slightest shit about them. He finds them useless and would gladly kill them at a moment's notice and surely will do.His personality far more interesting to me than Buu's. And the way he's interacted w/ other antagonists & teamed up w/ Galactic Patrol prisoners is far more interesting than just wreaking havoc across the universe.
Typical bad guy will kill his minions to show how bad of a guy he is. Something we saw with Vegeta, Lord Slug, Frieza, Bojack, Hearts, Mechikabura etc. It's just the same thing as always.
What actually would of been different would have been if he actually valued his minions but no it's always the same thing.
What else was so interesting about his personality? That he's so evil he'd kill a young Namek? Because Frieza actually did that already. That's he arrogant and cocky, sure that he'll defeat the good guys? Like every single antagonist.
He's awful, he's not charismatic like Frieza, he's not mysterious like Cell, he's not comical like Buu, he's not part of the series lore and history like Beerus, he doesn't have interesting techniques like Hit, he's not so two shaded like Zamasu, he's not cool or bad ass or imposing like Jiren or Broly.
He has nothing going for him at all. He's just like Lord Slug or Bojack. A forgettable basic villain that Toriyama had little to no involvement with.
