Goku's godlike power might make his time travel more precise. Normal time travel in the Dragon Ball universe can be a bit haphazard, but with his godly energy, he could target specific moments more accurately. For instance, he could arrive at the exact second he wants to in the past or future.
His godlike power could also potentially allow him to travel to different timelines more easily. Since his power is on a higher plane, he might be able to sense and access parallel universes during his time - travels. He could then interact with different versions of his friends and enemies, which would create really interesting storylines. For example, he could meet a version of Vegeta who became a supreme god in another timeline.
A great plot could involve Goku time traveling to the era of the Namekians before they faced the threat of Frieza. He could help them prepare defenses and train their warriors. Maybe he would also learn some of their ancient and forgotten techniques, like a super powerful healing ability. This would add a new dimension to his power set and also create a different relationship between the Z - Fighters and the Namekians.
In the 'goku is op and godlike as a baby fanfiction', Goku's power as a baby could be demonstrated in various ways. His senses could be highly developed, allowing him to detect danger or the presence of strong opponents from afar. He may also possess an inherent understanding of combat strategy, despite his young age. This could be due to some sort of genetic or mystical influence. Additionally, his physical abilities such as speed and agility could be far beyond what is normal for a baby. He could move with incredible swiftness and precision, almost like a miniature martial arts master, which is a clear sign of his over - powered and godlike nature.
If Goku travels back in time, his relationship with Bulma could be very different. In the past, she was more of a guide to him. But if he goes back with his current knowledge and power, he could become more of a protector for her. He might also be able to prevent some of the dangerous situations she got into in the original story.
His super saiyan form might give him extra protection during time travel. It could also make him more noticeable when he arrives in the past. Maybe the energy from his super saiyan form could disrupt the normal flow of time a bit more than if he was in his normal state.
Well, his relationship with Vegeta would be interesting. If Goku went back in time and showed Vegeta the SSJ God form too early, Vegeta might become more competitive or even jealous earlier. He might push himself even harder to catch up, which could lead to more intense rivalries and also more joint training sessions between them.

Android 18, with her strength and unique abilities, would be a great ally in this adventure. They might face challenges like dealing with the primitive technology of that time and also having to hide their true identities to avoid disrupting the timeline too much.
A being from a parallel Dragon Ball universe where the power levels are exponentially higher. This enemy would have a completely different set of techniques and abilities. For example, they could control the very concept of energy, not just ki, which would force Goku to adapt his fighting style in ways he's never had to before.
Another popular character is Beerus. Since he is a powerful god in the Dragon Ball universe, when paired with Godlike Goku, it can lead to some really interesting power dynamics. They could have battles that shake the very fabric of the universe or team up to deal with an emerging evil that threatens the balance of all the realms.
In some dark godlike Goku fanfictions, the story might explore how the other characters react to this new version of Goku. His friends like Vegeta and Piccolo would likely be shocked and conflicted.

Piccolo, being more level - headed, might try to figure out a way to bring Goku back to his old self.
One possible fanfiction could be Gt Goku traveling back in time to prevent the destruction of Earth in an earlier timeline. He could use his knowledge from the GT era to stop a powerful enemy that was previously victorious.
