Blocky

Blocky is shown to be malicious and reckless. He constantly targets and kills various people whenever given the chance, like popping Bubble, kicking Woody, throwing Ice Cube off a cliff, and extinguishing Firey repeatedly. These attacks are very often downplayed as "pranks" on his end, they usually are at the expense of other people's well-being, which clearly makes this bullying. Blocky hardly shows any remorse for his actions and is rarely social to people outside of his friend group. By the way, he's human in this.

Battle for BFDI In this season, Blocky's personality changes. He's a lot less violent towards others, killing people less often. He can still be pushed, like when Golf Ball tries to manage him, causing Blocky to break her in half. He's also more social and empathetic, standing up for Grassy when Golf Ball mistreated him, or worrying when Four was gonna come back. Blocky still wishes he could return to "pranks", but he acknowledges the improbability of the prospect and shows restraint.

His behaviour in episodes such as "Today's Very Special Episode" reflect his strong loyalty to his team members and a reluctance to break from group consensus. His decision to follow 8-Ball's misguided orders, even when it jeopardizes their success, shows that he values team unity over individual judgment. Blocky's actions also indicate that he may view authority and leadership as something that should be respected by the group's decision rather than based on competence alone, which is why he resists Golf Ball's attempt to take charge.

Battle for BFB "X Marks the Spot", shows that he's reverted back to his original personality, kicking Woody for the fun of it, as well as scaring Ruby with a pair of sharp "teeth" scissors. Additionally, instead of killing contestants as part of his "pranks", Blocky further extends it by causing mischief and sabotaging others during challenges, although it doesn't end well for him as he will sometimes turn up into an unfortunate fate such as getting killed or having his company sentenced for 2,763 years.

Blocky has a very hard time empathising with others and dislikes how they show weakness and failure, leading him to look down on them to define his successes, according to Taco. However, he learns to respect Woody when he sees that he isn't as paranoid as he used to be, along with learning that he's also capable of pranking.

Blocky does develop a sense of empathy once he learns that Woody had actually disliked pranking and had only done as such to impress Blocky and befriend him. Blocky comforts Woody and reassures him that they can find another thing to do together instead of "pranks". When Flower begins to panic over bugs filling the tank she was locked in, Woody gets her to breathe and try and calm her down. Blocky beholds this and praises Woody for helping Flower, using the opportunity to create a show where Woody helps people rather than hurting them.
