We all have anime characters we find similar in some way shape or form so why not put them all into one place? Look for some of the wildest comparisons and place them in this forum post! It can be anything alike we will accept it. Just post and have fun! 

Kenshin Himura and Raphael from "Rhythm Thief and the Emperor's Treasure". They both have red hair. They may not be strikingly similar, but it seems to me that red hair may be something a number of authors/artists/etc. use to depict someone with exceptional courage or moral capacity. Both Kenshin and Raphael have to do things that may not be fully enjoyable (Kenshin must fight, Raphael must take in a way many would call stealing), but they do it for noble causes. Kenshin fights to protect those he loves, including his enemies. Raphael seeks to find his father and discover why his father left him, while returning the original paintings his father took in order to make forgeries to provide for his son. However, the tone of "Rurouni Kenshin" and "Rhythm Thief and the Emperor's Treasure" is quite different. Kenshin is a bit of a goofball outside of battle, but in battle, he is quite serious. Raphael always finds a way to enjoy things, even his heists...perhaps even to his detriment. But despite this, both characters are shown as folks that are trying to do their best to do the right thing, despite their flaws.

Its not an anime, but Moriya Minakata from the game The Last Blade 1/2 has the same personality and sorta looks like Kenshin (they even have a similar sword style).
In Last Blade 2, Kaori Sanada looks just like Kenshin but with black hair rather than red.
Keiichiro Washizuka of the same series is modeled after Hajime Saitō.

If I am not mistaken though, the character designers liked Rurouni Kenshin so its not exactly coincidence that they look like those characters.

I would say....Natsu Dragneel from Fairy Tail and Yukihira Souma from an anime called Shokugeki no Soma I don't know much about the second anime, but I do know enough to say the main character resembles and acts like Natsu a lot. Because the same person who made fairy tail is the same person who made Shokugeki no Soma. I plan on watching it when I have the time too. Considering its based on a cooking type anime. So I would watch those sort of things.
