Helbram

Helbram「ヘルブラム」 was King's closest friend until his death at the hands of the latter for causing a human genocide for 500 years. After being revived by Hendrickson, he affiliates with the Holy Knights under a human appearance. He was killed during the Kingdom Infiltration arc, but his soul continued to reside in his old helmet thereafter, allowing King to communicate with him, until having his helmet crushed during a sacrifice.
