There's been a debate that I've noticed for a while in regards to which type of Ben is better. Many fans point out that the more mature Ben from Alien Force is the better Ben because they say it shows how he's developed and grown from the Original Series. Many fans point out that having the "cocky" Ben, or the more impulsive and fun-loving Ben, is the better Ben because they say it makes him a more enjoyable and fun character to have around.Well, here's my take on all of this and, in my opinion, who is the better and best Ben.
So let's start off with the more mature and serious Ben as seen in Alien Force. Honestly, I don't like Ben as this type of person because to me, it contradicts the type of person that Ben really and truly is. To me, it discredits him as a character. He just felt bland and generic and likely even cliched. Too serious to be a fun and enjoyable character to have interest in. It felt more like Cartoon Network just simply changed Ben instead of actually developing him. Now, this would be justifiable if maybe this was because something major happened that made Ben into the type of person that he is in Alien Force, likely even related to why Ben took the Omnitrix off before the events of the show, but this is never explained at all. However, this next point is where things get really contradicting for Ben. Remember when Ben met his future self for the first time in the Original Series? Remember when Ben 10,000 acted way too serious about his hero work and it made Ben view his future self as a jerk? That was the big kicker to me with Ben in Alien Force. Even though Ben's future self became one of the greatest heroes out there, he doesn't want to become that very person. He doesn't want to become too serious in his hero work because he doesn't want to become a jerk that lacks the fun and enjoyment in his life that he really enjoys. Despite the huge hero status that he gains, Ben doesn't want to become like Ben 10,000 and yet this, for the most part, is the very person he became in Alien Force. Again, this could be justified if something happened in Ben's life that made him that way but Cartoon Network never seemed to bother explaining what happened. Ben in Alien Force never actually grew up and never actually developed. He was changed into mostly a different person. One that he doesn't want to become and doesn't represent who he truly is and what made him such a great character in the series. That is why the more mature and serious Ben doesn't really work for him as a character and for the series.
So what about "cocky" Ben, huh? What about the side of Ben that is impulsive and fun-loving? In some cases, it was better but in other cases, it made Ben as a character even worse. This was most especially in Omniverse where Ben would just act so ignorant and arrogant and so immature and it quite often made him a more obnoxious character in the series. It still didn't feel like that this was the actual and true Ben. It felt like that everything that he learned and went through in the Original Series was thrown out the window. This included how Ben and Gwen's relationship developed in the Original Series. Ultimate Alien was more balanced with this but there were still times where Ben just ended up being more obnoxious than fun and enjoyable to watch. Cartoon Network just ended up dumbing him down way too much, in my opinion, and just also doesn't really represent what made him such a truly great character in the Original Series.
Ok so, if neither mature Ben nor "cocky" Ben in the sequels worked for the series and made as great of a representation of him as a character as the Original Series did. So what made Ben in the Original Series great, then? Well, it wasn't that he was mature and serious or impulsive and fun-loving but instead it was that he was both. Ben enjoyed having fun yet he takes the very situations that he's in serious enough to not let his ego get in the way. Early in the Original Series, he acted arrogant, ignorant, and immature but as the series progressed, he grew and developed and improved himself to take his hero work more seriously and be more intelligent and strategic in tackling each of his battles yet he still remained the same person that we saw him as at the end of the Original Series. In the Original Series, he never changed as a character but better yet improved himself as a character. That is what I mean by Ben being at his best when he is both impulsive, egocentric, and fun-loving character yet also shows to be mature and serious as well. It made Ben both an enjoyable and fun character yet a strong and well developed character as well.
There's my take on this debate. In my opinion, it's better for Ben to be both mature and serious and impulsive, egocentric, and fun-loving. This allows him to be both an enjoyable, fun, and entertaining for the viewers yet also give him a chance to grow and develop and improve himself as a character and that is how he was represented as in the Original Series. If anyone has any thoughts and opinions on this subject, feel free to comment about it.
Later on, I'll be making another discussion page where I discuss a weird yet surprisingly popular concept about Ben and Gwen being in a romantic relationship, even though they're cousins, and my opinions on this concept and why it's so popular amongst fans. I have discussed this on my GoogleDoc article (which I left a link to on my "Addressing the Ben 10 Reboot" topic page) but I'm going to make a page about it to give others a chance to discuss their thoughts and opinions on this concept as well.
