Bloqueo Es un pequeño niño de Truco o trato Vestido con traje rojo con zapatos rojos y puntiagudos, y Una máscara roja para acompañar el traje, haciéndolo Parecer ONU demonio. La cola parece ser real y se encuentra moviéndose por sí sola a lo largo de la película. Su piel es de color blanco alabastro, mientras que su cabello y sus cejas son de color rojo rubí, ajustándose a su traje de diablo. Es uno de los tres antagonistas secundarios en la película.
He is the middle child of the three, with an age of nine and isn't revealed to be the leader until the Kingdom Hearts series.
He is, alongside Shock and Barrel, Oogie Boogie's henchman, but doesn't seem to be loyal to him, since he's often found doing odd jobs for Jack, too. He often quarrels with the other two Trick or Treaters and doesn't like it when he's being insulted or disrespected.
He and his cohorts are given the task to travel to Christmas Town and kidnap "Sandy Claws". On their first try they mistakenly take the Easter Bunny instead, which angers Jack, and are told to take the frightened Holiday Spirit back to his own world. They succeed on the second attempt on bringing "Sandy Claws" to Jack.
When Jack tells them to make the Christmas Spirit feel comfortable, Lock decides he should be shown to Oogie Boogie.
Later on when everyone in Halloween Town believes Jack is dead, Lock and the others "find" Santa Claus in Oogie's lair and lead the Mayor to him.

- It is possible if he could be an actual Devil due to his fake tail usually moving a lot
- It is possible that they could be siblings, as Lock and Shock have similar faces. It is unlikely, though, as if this were the case, Danny Elfman would have used the word 'brothers' or 'siblings' in the "Kidnap the Sandy Claws" song, rather than "cohorts."
