To initially hide this fact, he acts timid and runs away in the face of danger, a farce that Tomoko Nozama easily sees through, but after his identity is revealed to the Kamen Rider Club upon the discovery of the Aries Zodiarts, he drops the pretense after he officially joins the Kamen Rider Club. After Sagittarius Nova's defeat, Ryusei returns back to Subaruboshi High School. Ryusei as Kamen Rider Meteor first appears in a post-credits scene of Kamen Rider × Kamen Rider Fourze & OOO: Movie War Mega Max, defeating the remaining members of Foundation X under Lem Kannagi while wondering if the Aries Zodiarts will be at AGHS.
Kamen Rider Meteor's abilities arise from Cosmic Energy. However, compared to Kamen Rider Fourze's arsenal, the Meteor System was not devised by Kengo's father and instead was built by Kuniteru Emoto. The energy for Ryusei to transform into Kamen Rider Meteor comes from the M-BUS satellite in orbit, with Ryusei needing Tachibana's approval to transform and may even shut it down while he is assuming his Rider form. After transforming into Kamen Rider Meteor, Ryusei says "Kamen Rider Meteor, I'll decide your fate!" Kamen Rider Meteor has two Limit Break finishing attacks on his own. The first is the spinning attack called the Meteor Tornado and the second is a Rider Kick called the Meteor Strike. Kamen Rider Meteor's helmet is called the Starface. When using the Elek Switch, electrical currents flow through Kamen Rider Meteor's body, enabling him to control electricity. He can also perform a Limit Break attack that is a variation of the Meteor Strike Rider Kick.
