If me and my sibling's AU were in the same universe: Yellow Guy and 'Danny' are best friends, they share some hobbies and play games! Yellow thinks of 'Danny' as his younger brother. (Danny has one good battery and one bad one) Duck Guy and 'Wally' can tolerate each other, though they do sometimes argue about who's better, or just anything really if they're that bored. Otherwise, they just talk about what's in the daily paper or what else is bothering them. 'Jason' is the more mature one, looking after 'Danny' and 'Wally', he treats Danny like his own son and will protect him. 'Jason' and Red Guy usually are the calm ones so they get along just fine.
Characters: 'Jason' 'Red Guy' 'Wally' 'Duck Guy' 'Danny' 'Yellow Guy' (Don't steal our designs! This applies to both versions.)
