!!Aruto Hiden/Kamen Rider Zero-One/Kamen Rider Zerozero-One/Kamen Rider Zero-Two (I)/Kamen Rider Ark-One

** While [[Series/KamenRiderExAid Emu Hojo]] and Aruto are {{All Loving Hero}}es of their respective series, and are the primary Riders of their respective series, that may be the only similarity. Emu is an unpopular doctor [[spoiler: and also the PatientZero]] who values everyone's lives [[spoiler:due to an incident caused by his PatientZero infection]], while Aruto is a president of a famous company who got the position via {{Nepotism}}. Both see humanity in another race (Bugsters for Emu, [=HumaGears=] for Aruto), but Emu spent most of his time opposing Bugsters due to them being naturally human's enemies, while Aruto spent most of his time caring for [=HumaGears=], only fighting them when he has no choice to. Emu also refused to sway from his heroic nature, even when some of his friends wound up dying, [[spoiler: while Aruto [[DespairEventHorizon was traumatized by Is's death]] long enough to [[BecameHisOwnAntithesis accept Ark's power.]]]]

* JustForPun: The Zero-Two Driver's transformation jingle likes exaggerating the ''to'' in the jingle, since its used by Kamen Rider Zero-''Two.'' Looks like Aruto's sense of humor rubbed off on his equipment.
