It's just that I've noticed a lot of similarities between Godot and Enishi.

First, the hair style and color - They both have spikey hair. Both their hair colors weren't naturally white. Enishi's hair turned white because of anger while Godot's hair turned white because of the poison (if I remember right).

Both are wearing vest-like clothes - Godot's wearing a long sleeved polo under the vest while Enishi isn't. But still, they're still wearing clothes of similar style.

Both are damaged characters and angry at the protagonist - Godot hated Phoenix because he believed it was his fault that Mia died while Enishi hated Kenshin because he killed Tomoe. The reason for hatred of the two are very similar because they believed it was the protagonist's fault why they both lost the closest and most important person in their lives.

Both characters appear at the end - Godot appeared only in Trials and Tribulations. Enishi appeared only in the Jinchuu arc, which is the last arc of the story.

What started it, happened in the past. Before the current time setting of the game/manga - In Godot's case, it began the moment they met Dahlia. We see this part in the game but it's actually a flashback of what happened several years before the current setting. In Enishi's case, it began the moment Tomoe met Kenshin which was shown somewhere in the middle of the manga as a flashback while Kenshin was telling his tale.

And last, since I can't think of anything anymore, they saw the image of their most important person at the end! - Godot saw an image of Mia doing the super objection along with Phoenix at the end. Enishi saw an image of her sister in Kaoru at the end when Kaoru uses her body to block Kenshin from Wu Hei Hsin's view in order to protect him.

Well, that's it. I just felt like sharing it again.
