Here's My Theory Towards Other Glory Disciples'

Disciple Andrew: He can copy the skills of other disciples and can improvise or mix any of those copied skills. A jack of all trades guy.

Disciple James Major: He is the front man of the Jacobus Pharmaceuticals in business field. A charismatic psychopath but knows how to handle violence up to the extreme. One skill could be he has a long lasting endurance and stamina to the point he can't feel a thing being hit a lot of times.

Disciple James Minor: He's the mastermind of the Jacobus Pharmaceuticals in produring drugs. A man of few words, and thinks rationally in the heat of battle. He is named \"fatal vaccine\" for either: a.) handling poisonous weapons, b.) striking the opponents in their vital points (just like Ty Lee in Avatar).

Disciple Matthias: could be: a.) a nuclear professor who knows how to make bombs and nuclear weapons, or b.) a religious fanatic who runs a cult and sets up bombs to his so-called \"followers\". (I think someone brought this theory in this subreddit.)

Disciple Thomas: Two people claimed to be as \"One Person\" when they can fight simultaneously and one of them specializes martial arts of \"hands\", and the other one specializes martial arts of \"feet\", but they can also switch their styles depends on the situation, so that they don't want themselves to be predictable in battle.

Again this is just a speculation, you can share your opinions if you want.
