Squire is the name of three superheroes appearing in media published by DC Comics. Percival Sheldrake debuted as the Squire in Young All-Stars #21 (January 1988), and was created by Roy Thomas and Michael Bair. Cyril Sheldrake debuted as the Squire in Batman #62 (December 1950), and was created by Bill Finger and Dick Sprang. Beryl Hutchinson debuted as the Squire in JLA #26 (February 1999), and was created by Grant Morrison and Howard Porter. The fourth Squire, Amina Eluko, debuted in the limited series Batman: The Detective and was created by Tom Taylor and Andy Kubert.

Originally created in the 1950s as a counterpart to Robin for the Knight, a subsequent retcon made the Knight himself Squire to the original hero, the Shining Knight .

First appearing in the pages of Batman #62, Cyril was Percy Sheldrake's son, who was trained in manner much like his father had been, thus becoming the new Squire. They were constantly compared to Batman and Robin, and they considered themselves to be their European counterparts. Coincidentally, the dynamic duo made their way to England on one occasion, where they met up with Knight and Squire and formed an alliance to take down neo-Nazi supporters at their hidden base at Stonehenge. Percy was eventually killed by his arch-enemy Spring-Heeled Jack, leading Cyril to become the second Knight. Cyril subsequently joined the Ultramarine Corps, alongside his own Squire, Beryl Hutchinson.

He reappears in Batman #667-669. He, Beryl, Batman, Robin and the rest of the Batmen of All Nations, sometimes known as the "Club of Heroes", have become trapped on an island. It was seemingly to be an innocent reunion sponsored by their billionaire benefactor, Mayhew. All the possible transports off the island have been destroyed and everyone currently believes their lives to be in danger, as the Legionary and Wingman have been killed.

At age 20, young Percy came into leadership of his family (thus becoming Earl of Wordenshire) when his father was captured in France and his mother was killed in a terroristic attack raid over London. About this time, another knight from the Middle Ages known as the Shining Knight had recently thawed out from centuries of suspended animation and was assisting the war effort in his native land. Unable to save either of Percy's parents, the knight vowed to bring the villains to justice and end their regime once and for all. He took Percy under his wing and trained him just as a knight would train a squire in his original 6th century Camelot. He bestowed upon him the name Squire, and with the help of the Seven Soldiers of Victory, they fought against the evil and crime.

During his adventures, the Squire was also part of a team of adolescent superheroes called the Young Allies. Remaining together after the war, they fought against the rising threat of post-war nationals in Europe until inner conflicts caused the group to split up. Now on his own, and feeling his requisite training had been complete, Squire bestowed upon himself the name Knight, and joined yet another team (the Global Guardians) under this new name. He continued to fight for justice even after he fathered a son years later named Cyril.

Beryl Hutchinson first appeared in JLA #26 (February 1999) and became the new Squire while assisting Knight II. According to Grant Morrison, she was named after Beryl the Peril, a popular British comic-strip. Brave and courageous, she and Knight joined the Ultramarine Corps of Superbia after assisting them in saving a crime-ridden micro-Earth. As well as being an expert in swordplay, she is also naturally gifted in several forms of communication, including foreign languages, gestures, and interpretation. She can even read information patterns by touch. She cares a good deal for Cyril and will protect him at any cost.

While the Sheldrakes are nobility, Beryl apparently grew up on the streets. With regard to her education, she explained to Batman "the Hutchinsons never had no money, but they always had brains and a love of the library". In contrast, in Knight and Squire #1, she says she "went to a lot of different schools. State ones and posh ones, back and forth". She attributes her communication powers to this, since she needed to shift dialects rapidly to match the school she was attending.
