Allen (past)

Allen (アレン, Aren)  was a supporter and friend of The 14th Noah 35 years prior to the story. A lot of mysteries surround him including the name he shares with Allen Walker/Red and Mana's dog, Allen.

Appearance
Allen has long light hair partly tied in a chignon in the back and a fringe. He wears civilian clothing and round glasses.

Personality
Allen appears as a knowledgeable man in Nea's memories. He is a faithful man willing to sacrifice himself to allow Nea to fulfil his goal. He is seen smiling with a rather calm demeanour.

History
35 Years ago, Allen was supporting Nea in his fight with the earl. Before Nea died he proposed himself to be his next vessel after his death. He was seen approaching a badly wounded Nea in an alley and swearing to protect his memory.

He was the one who told Nea about the Helix of Life. He was aware of the Earl's soul devouring ability and explained it to Nea. Cross Marian was aware of the reincarnation plan since he was looking for "Allen" when he met Allen Walker (Red).

Abilities and Powers
Scientific knowledge: Allen seems to know a lot about the helix of life, the source power of life.

Trivia

 * It is currently unknown who exactly Allen is. He has fuelled many fan theories including him being Allen Walker whose body somehow rejuvenated.
 * Mana Walker's dog was also named "Allen". It is unknown if there exists a link between the two.
 * in Chapter 234, Cross comments on how Mana  even named the dog after "Allen". Assuming that he referred to the same Allen Nea was affiliated, this could imply that Mana and Allen (past) knew each other beforehand.
