Yahoot

Yahoot, known as Mahajarama (マハ・ジャラマ) in Japan, is the operator of MagicMan.EXE and a former WWW member. In the game, Yahoot was Wily's right hand man.

Mega Man Battle Network
In the game, Yahoot spends most of the time by Wily's side, assisting him with his plans and relaying orders to the other WWW members. When Lan entered WWW's base, he and MagicMan guarded the door leading to the Life Virus. They were initially defeated by MegaMan, but Wily gives Yahoot a piece of the Life Virus's code, which he uses to upgrade MagicMan. MegaMan is no match for MagicMan's newly acquired strength, and is almost deleted in a single attack. Chaud and ProtoMan.EXE intervene, deleting MagicMan as he's charging a new attack to finish off MegaMan. Yahoot is not seen again after this point, and presumably fled.

MegaMan NT Warrior
In the anime, Yahoot had a much more prominent role compared to his video game counterpart. He was the host of a popular yoga television show. However, he was a member of the WWW and uses the shows popularity to wreak havoc by hypnotizing everyone watching it and making them lose control. However, he fails in his plans, because Maylu and Lan did not watch his show with everyone else. They challenge him and MagicMan who loses.

He later participates of the N1 Grand Prix and fights against MegaMan, but is defeated by a Program Advance. He later poses as Higsby and gives a rare chip with negative effects to Maylu. The battle chip turns Roll against MegaMan, and she almost deletes him when the real Higsby arrives and tells them how to remove it.

After the downfall of Wily and PharaohMan, he and the other three WWW members open a curry shop, with Yahoot working as chef, to raise funds to revive the organization. But, with time they start to live an honest life and didn't joined Wily after his return (but then again, Wily had no intention of reviving the WWW).

Trivia
