Super Happy Bandwagon Fun Times, Critique my Characters

I'm not exactly Gramps or Flora in the people-having-opinions-of-my-characters scale (No offense intended), but hey, all the cool kids are making these threads. Here's a list of my more active characters and what I think of them, please give your opinions below.

Amson - My first and, I think, best-known character. Lawful good Glitch knight, my personal favorite if a bit dull at times. He originated on another server, where he went through a lot of his main character development, and I feel like recently I've gotten into a bit of a rut - beam down on Taranis, stop a bar fight, make some sarcastic comments, rinse and repeat.

Johnson - RA soldier most of you have never heard of, probably. I had some bigger plans for him that fell apart rather quickly, but I still liked the character so I put him in the RA. Now the RA is gone so I've put him on indefinite hiatus.

Jameson - Apex who sells guns, my personal Starcheat experimenter. I haven't managed to get in much character development for him, since most of his interactions with people are beaming down for five minutes to hand over some rifles. I got a bit of use out of him for the ape flu event, though, so that was fun.

Ryan - He's the bartender at the Wolves Den who's always there IC whether I can be bothered to sit at a bar OOC all day or not. He was born out of a desire to have a moderately /normal/, noncombat character with plausible skills and aspirations, and then got shot in the head on his second day of work.

Note that most of my characters' names end in a variation of 'son'. I have no idea why, and I don't plan it like this. Gib opinions, or if you can't do that, gib clay.
