TopMan appears randomly as an opponent in the first tournament. He first appears when Tensuke's top malfunctions. After Lan helps him, TopMan is revealed to be a makeshift Navi, a Navi his operator created by himself using his own parts. This means that TopMan breaks down frequently and is shown to have some memory loss as well, as he forgets he is in the tournament, urging Tensuke to finish the prelims, upon which Tensuke yells at him reminding him the prelims are far over. Tensuke is too prideful to ask for help fixing TopMan and leaves him in that state. Tensuke's twin brother is convinced by Lan to help fix TopMan (although he pretends it is out of pity), and the two go to fight MegaMan.EXE in the tourney so Tensuke can prove to his grandson Kosuke that tops are still cool. Although he loses, the two succeed in impressing Tensuke's grandson.
TopMan is a very odd behaviored Navi, who belongs to an older gentleman named Tensuke. These two old timers act just like each other, right down to their very stubborn attitudes and their love for tops. TopMan isn't very bright when it comes to NetBattles, which may be a result from Tensuke not knowing much himself about the game and its rules.
Powers and Abilities
Little Spinner: TopMan sends three tops that move in a diagonal fashion and bounce off edges. The tops are invincible. The tops behave nearly identically to the "AirHoc" chip, the only difference is that there are two of them on the field.
Top Spin: TopMan turns into a giant top and spins to your area, damaging you if he hits you, then spins back to where he started. He is invincible in this form.
Grinding Top: TopMan turns into a giant top, disappears, and then falls on your position. He is invincible in this form.
