Dr. Crossword Arno (クロスワード・アルノ博士(はかせ), Kurosuwādo Aruno Hakase) is a character introduced in Inazuma Eleven GO Chrono Stone.


Dr. Arno is partially bald, with cream-coloured hair. He has bushy eyebrows and a bushy mustache of the same colour. He wears an eyepatch-like device on his left eye. He also wears a white/blue jacket, coupled with black shorts and white/blue shoes.



Dr. Arno is an expert in advocating the theory with multiple timelines and he also invented the method of entering into a wormhole.


A New Threat

Dr. Arno first appeared in episode 5. He explained and parallel worlds and how time travel worked. Since no other member from Raimon seemed to understand his explanation, Yamana Akane simplified the explanation because of her interest in science fiction.

He appeared again in episode 6, driving the Inazuma TM Caravan and said to Raimon to come in the Caravan to leave the match.

He appeared another time in episode 7. He stopped by to confirm that Gouenji wore a Time Bracelet and somehow knew him. He explained that he was also trying to make a kind of antidote to save Endou Daisuke from the Chrono Stone.

Sengoku Era

In episode 12, he appeared again and explained why Shindou couldn't Mixi Max with Oda Nobunaga. The reason the Mixi Max couldn't work was that Nobunaga was too strong to be fused with Shindou. He said that Shindou had to train to become as strong as Nobunaga, and then master Keshin Armed.

Jurassic Era

He appeared again in episode 31, talking about Perfect Cascade. He also said to Fei that the situation is worse, as El Dorado was now using their ultimate team. Later, he explained that after knowing about Zanark Domain's failure against Raimon, El Dorado had previously passed the Time Paradox effects to Perfect Cascade. This meant that Fei and the others would need to beat them.

King Arthur Era

He reappeared in episode 35 to explain that traveling to a fictional world was different from time travels. He also added that they needed an artifact of King Arthur, after which Nanobana Kinako got King Arthur's crown.

Ragnarok Tournament

In episode 47, he successfully brought Endou Mamoru back to his real form.
