Saitama from One Punch Man could be a contender. His ability to defeat any opponent with a single punch might just work against Goku. However, Goku's diverse skills and transformations would make it an epic battle.
Well, Doctor Strange might have a chance. His mastery of magic and strategic thinking could give him an edge.
I don't think so. Comic Thanos has access to cosmic powers and strategies that could pose a serious challenge for Goku. His intelligence and the extent of his powers might be too much for Goku to overcome.
I think it depends on various factors. Goku's determination and growth are remarkable, but Beerus has an overwhelming level of power and authority that might be difficult to overcome.
Superman might be one. With his array of powers like super strength, flight, and heat vision, he could potentially overcome any challenge.
I don't think so. Goku's power levels and abilities are on a whole different scale compared to Ichigo.
Shinra stands no chance against Goku. Goku has gone through countless battles and has mastered powerful techniques. His strength and experience give him a huge advantage.
Wonder Woman is a strong contender. Her combat skills, indomitable spirit, and divine powers make her capable of taking on Thanos. Plus, her lasso of truth could potentially force Thanos to reveal weaknesses.
It's debatable. There are many strong fictional characters, and it depends on various factors like powers, abilities, and the context of their stories.
It depends on your personality and interests. Maybe you can relate to characters like Harry Potter if you have a sense of adventure and bravery.
Another way is that Goku could use the Spirit Bomb. He could gather energy from all living things on Earth and nearby planets. Android 21, being an artificial being, might not be able to withstand the pure energy of the Spirit Bomb. However, she could try to absorb the energy, but if Goku can overload her absorption capabilities, it would be his victory.
