Kamen Rider Den-O

I recommend Den-o to Zio because both of them are Tokusatsu.
but the other reason I Recommend Den-o is because they use Time Travel concept. Also the main characters are Developing from weak to strong.

Both are train themed shows that are rather lighthearted and both are by the same writer.

In the sixteenth Heisei era Kamen Rider series, which is also the twenty-fifth installment of Kamen Rider franchise, Shinnosuke Tomari, a young detective in Special Investigation Unit of the Metropolitan Police Department fights against the Roidmudes, a race of robots fighting humanity for supremacy lead by Heart and Brain. With the help of his partner/scientist mentor/Transformation belt Krim Steinbelt, Shinnosuke becomes Kamen Rider Drive, A man made hero with the powers of automobiles.

both have monsters that come out of them that allows them to change into Kamen riders. they are always bickering and fighting like siblings but when it comes to fighting they work together

Both are tokusatsu shows written by a well-established female writer about a late-teen/young adult man who is surrounded by characters voiced by famous seiyuu. The lead character lives his daily life with a surrogate parental figure who runs a shop, after losing his parents at a young age.

The secondary, seiyuu-voiced characters also just happen to include an old-fashioned guy, an animal lover who only likes cute things, and a more nerdy/motherly character in both shows. However, while they are both color-coded, the personalities do not align to their similarly-colored counterpart.

And while Kamen Rider Den-O has the characters traveling through time to stop the bad guys, Kikai Sentai Zenkaiger has the parallel worlds come to them instead.

Kiva is the series following Den-O so if you want to watch the Kamen Rider seasons in order watch Kiva after Den-O.

Den-O is the series after Kabuto so if you are watching the Kamen Rider seasons in order watch Den-O after Kabuto.

Both feature time traveling
Both were written by Yasuko Kobayashi
Both feature characters from time(past/future)
Both feature "tough/strong yellow" archetypes

Both are written by Yasuko Kobayashi and so a lot of the same themes will be present. But also, both feature a group of non-human comedic characters that are partnered with the heroes and voiced by popular voice actors.
And the ending song for Go-busters is performed by the musical group, STARMEN. One of the members of said group was also the voice of Ryuutaros from Kamen Rider Den-O.

Set in Nagoya Station, it depicts the encounters of young people who work late at night and what happens after that.
