But that said, they could change up some things. NO MORE ANTOINE! Replace him with... a good character!
Define Good.
See if you mean a more competent character, that would be a bad idea as then he would become more bland and not stand out compared to the rest of the team.
In fact out of all the characters I'd cut Bunnie, Tails, Rotor, and Snively (In that order) before I'd cut Antoine.
Bunnie is so underdeveloped you could easily replace her with someone else.
Tails's only saving grace is he's a SEGA character. In SatAM he was pretty much useless and underused save for a gimmick to make the other character's lives more difficult.
Rotor's only personality is Tech Guy. Only one time in the show does he be anything more than that and in that episode he decides he only wants to be the tech guy at the end.
Robotnik would be just as evil without Snively or if you replaced him with a robot. Snively's biggest contribution is the fact that he has more personality then the characters listed above, specifically in the second season.
Antoine is far more developed personality and the perfect foil for Sonic.
Sonic is rude and messy, Ant is very polite and a neat freak. Sonic is brave, Ant is a coward. Sonic tends to make a joke of everything, and Ant takes it all too seriously.
Honestly he is a very well made character. Is he likeable maybe not so much but...well made.
Okay, I guess I should be... more.....
Snively? B-but..... *weeps softly to himself*
*ahem* I guess I should be more specific about why I don't like Antoine. Bunnie and Rotor are perhaps somewhat boring, but they have potential. Antoine...
So basically, here's how I see it. The guys at Dic were like, Hey, we need a comedy character! What's funny... Oh hey, there's the stereotype of the cowardly French military, so let's make this French coyote who's a coward, and who always wearing a military outfit! *The rest of the Dic team start LOLzing themselves*
So yeah, he really is just a stereotype. And on top of that, they make fun of him for not being able to speak English well. That's really obnoxious. The average French person can speak English very well, whereas the average American is only fluent in English.
What Archie has done with him is even more bothersome. In issue #46, they established that he wears his uniform to honor his late father, who was a military hero. Right after that, in Sonic Super Special #1, we have the story "The Map," which is clearly pro-war propaganda. If you've seen it, you'll know what I mean. It's old now, but it was reprinted in a Sonic Super Digest. And then finally we have issue 234, which has pro-war undertones, although more subtly.
This isn't the part of the forum to discuss serious issues such as war, but suffice it to say that -- while I have nothing against people who have fought in the military -- I do not like pro-war propaganda. Granted, there isn't a lot in the comic, but what's there does bother me quite a bit.
I don't hate Antoine. I loved him when I was a kid, and "Hooked on Sonics" is still one of my favorite episodes of SatAM. But still, I find him to be a rather problematic character, and if SatAM got a second chance, I'd really rather see him replaced with a different comic-relief character.
