I don't like that you are just posting images without explaining WHY the character design is good.
And I don't like the fact that you are posting a bunch of shitty character designs as well.
Subjective? Maybe.
But at least nobody has posted Final Fantasy X characters.
Do go into depth and detail WHAT makes good character, because otherwise I just see a bunch of images and suspect people like them "because they were cool".
I wasn't going to bother going into 'depth and detail' just for you and your shitty attitude, but I'm in a good mood this morning and feel like writing my thoughts down anyway.
Indiana Jones- There's so many memorable visual aspects to his design. The fedora is now synonymous with him. The whip and bomber jacket add to a really unique and definitive look. He's recognizable by just his silhouette, a hallmark of great character design. He's one of the few live-action characters I can think of that has a color-scheme: He's dressed entirely in shades of brown.
Optimus Prime- He's really iconic for a robot, and the most immediately recognizable of the transformers. The use of the truck's front design to imply musculature such as pecs and abs for the robot's chest is really clever in my mind.
Stitch- I'm a fan of Chris Sanders' designs in general, but what I like about Stitch specifically is how he both looks strange and familiar at the same time. You almost think he's based off a real animal, until you analyze it and can only conclude he's unique. The flow and curves of the shapes in the design also really work well.
Marceline from Adventure Time - I kind of chose her to represent Adventure Time in general, which has a look that I think is really fun and unique. But I like her design in particular because of two things- she seems inspired by a real person, like the designer knew this jaded punk rock girl who slouched and wore her sleeves just past the wrist. Also, the two bite marks on her neck tell part of her story, and add to her character by almost looking like a tattoo.
