The Kratt Bros!
1. Mk was more smart creatively in school while Ck was more smart academically (not based on anything irl)
2. Mk Stims. Alot. Specifically with his hands and legs. More on his hands though , Chris usually helps Martin out with it
3. Both bros are Extremely protective of each other. Just show it in different ways. Martin is the "I'll shield you" way and Chris is in the "I'll punch them if they try ANYTHING" way. Actually scratch that, the both of them are both ways! Just one side they show more than the other
4. Chris hates Physical affection, and doesn't like it when the rest of the Tourtuga crew just try to give him a hug or accidentally rest on his shoulder, he'll immediately ask for you to back away or he'll slowly move away himself
Not with Martin though, His older bro can be as physically affectionate as he wants towards him! And all though Chris just says he "doesn't mind" when the crew asks, in reality, Chris loves it. And Martin knows. He just doesn't like showing it (unless it's just the two of them)
Anyway i have more but that's for another time! I just love brother fluff sm, And here's a photo set of the bros 2!
