(Doesn't know what to say, since most have covered it)
Though I am a
huge Herriman fan, Wilt is in my top five. He's just the perfect role-model, the type of person you would want as a big brother. I may not be one of his fangirls, but I have mad respect for him. He's the type of friend you wish was around all the time.
Character design wise, he is fun to watch. I love the movement, and the wobbling of his eye. The red really suits and goes well with the blue and white. Hehe, reminds me of the Globe Trodders...
Voice wise...he is very soothing. I feel like things are safe, and will be okay when I hear it. (Does anyone else have those feelings?)
Okay, okay! I love the big guy! Not in terms of relationshipness, but...I just want to hug him!
(And I really don't do this often, but GWH made me very sad. Almost to the point of tears. Again, I'm not that type of person to get emotional about movies and shows...)
