human blocky headcanons:

• human name is daniel bae (pronounced beh) but he insists everyone calls him dan

• blocky is actually the nicer one of the two, vs eraser. blocky is “mean” but only in a playful sense and knows more when to stop. a lot of his acts of being mean pertain the his pranks. he’s actually a really nice uncle/big brother figure.

• speaking of uncle, i do have a headcanon woody is his nephew in my au. he watches him from time to time. semi related is the fact that i think he’d have a few siblings. He’s only one block in the whole block family

• pen clings to blocky more seeing as blocky takes the time to treat him normally. pen usually runs back to blocky when eraser finally snaps at him for things usually out of his control, and blockys there to reel eraser back in when he feels him getting antsy. eraser is very mentally ill and bad at regulating himself, and while blocky is also mentally ill (mostly without knowing) he is more socialized and can navigate his emotions better. he’s just really an average cis guy who loves to be on instagram and likes to be with his friends

• the three of them usually hang out at erasers (mom’s) place specifically in this downstairs basement type area that was turned into erasers room. this is kind of unrelated but i just wanted to describe that. they often have sleepovers

• in the au, eraser and blocky were middle / high school best friends. they lost touch shortly after high school but rekindled their bond to the best of their ability. eraser is still bitter about stuff he won’t bring up.

• shortest of the three. i usually don’t like super short man short king headcanons but with blocky it fits his character. he worked out before but has let himself go . did taekwondo as a teen

• he is a very… average man. he has normie interests. his choice of video game console is the ps4, he likes instagram memes, his childhood game was pokémon. he is genuinely kind of cringe but it’s a bit endearing. he really is just some guy
