If SpongeBob had Omni Saiyan abilities, he would be nearly invincible. With the ability to transform into any form or evolution at will, he could easily adapt to any situation and overcome any challenge. His Saiyan physiology would also give him superhuman strength, speed, and durability, making him nearly indestructible. With his new powers, SpongeBob could potentially fuse with other characters to create even more powerful beings. He could fuse with Goku, Vegeta, or even Frieza to create the ultimate Saiyan warrior. His evolutions could also be utilized in battle, as he could transform into a Great Ape to gain even more power. Overall, SpongeBob would become an unstoppable force with his Omni Saiyan abilities. He would be a force to be reckoned with, capable of taking on any opponent and coming out victorious.

SpongeBob (with Omni Saiyan + All Forms / Evolutions /Fusions + Saiyan Physiology) would easily defeat Axel Stone from Streets Of Rage. Axel Stone is a skilled fighter, but he lacks the incredible strength and abilities of a Saiyan. SpongeBob's Saiyan physiology would give him superhuman strength, speed, and durability, making him nearly invincible. He could easily dodge Axel's attacks and deal significant damage to him with his own attacks. SpongeBob could also transform into any of his forms or evolutions to gain additional power and abilities. In addition, if SpongeBob were to fuse with another character, he would become even more powerful. The fusion could potentially put him on a level far beyond anything Axel could ever hope to achieve. Overall, SpongeBob with all of his Saiyan abilities would be too much for Axel to handle. Axel may be a skilled fighter, but he simply wouldn't have the power to match SpongeBob's incredible strength and abilities.

If SpongeBob and Goku fused together (with Omni Saiyan + All Forms / Evolutions /Fusions + Saiyan Physiology), the resulting warrior would be incredibly powerful. The fusion would create a being with the combined strength, speed, and abilities of both characters, as well as all of their forms and evolutions. However, Vegeta is one of the strongest warriors in the Dragon Ball universe, so defeating him would not be an easy task. Vegeta is incredibly skilled in combat and has a wealth of fighting experience. He is also a master strategist, so the fused warrior would need to be careful when attacking him. However, with Goku's experience and SpongeBob's quick thinking, they could potentially outmaneuver Vegeta in battle. The fused warrior would have access to the full range of Saiyan forms and evolutions, including Super Saiyan, Super Saiyan God, and Great Ape. These forms would give them incredible strength, speed, and durability, making them a formidable opponent. Ultimately, the battle between the fused warrior and Vegeta would come down to the strength of their attacks and their ability to outmaneuver each other. However, due to the incredible power and abilities granted by the fusion, the odds would be in favor of the fused warrior. They would be able to hold their own against Vegeta and potentially come out victorious.

SpongeBob (with Omni Saiyan + All Forms / Evolutions /Fusions + Saiyan Physiology) would easily defeat the Streets of Rage Universe. The Streets of Rage Universe consists of skilled fighters, but they would simply not have the strength or abilities to match SpongeBob's incredible power. SpongeBob's Saiyan physiology would give him superhuman strength, speed, and durability, making him nearly invincible. He could easily dodge attacks from the enemies in the Streets of Rage Universe and deal significant damage with his own attacks. Additionally, his ability to transform into various forms and evolutions, as well as fuse with other characters, would make him an even more formidable opponent. The characters in the Streets of Rage Universe may be skilled fighters, but they lack the incredible power and abilities of a Saiyan. SpongeBob's quickly adapting in battle according to the situation, along with his immense power, would make him nearly unstoppable. Overall, the Streets of Rage Universe would not stand a chance against SpongeBob with all of his Saiyan abilities. He would effortlessly take out any opponent who stood in his way, leaving destruction in his wake.

SpongeBob (with Omni Saiyan + All Forms / Evolutions /Fusions + Saiyan Physiology) and Tommy Oliver/Green Ranger would be a close match, as both possess incredible power and abilities. Tommy Oliver/Green Ranger is a skilled martial artist with a wealth of combat experience. He is also a powerful ranger with access to a range of weapons and abilities. His Dragon Shield would also give him enhanced durability, making him a formidable opponent. However, SpongeBob's Saiyan abilities would give him superhuman strength, speed, and durability, as well as the ability to transform into any form or evolution at will. He could potentially fuse with other characters, giving him even more power and abilities. The battle between SpongeBob and Tommy would likely come down to their ability to outmaneuver each other and use their respective powers and abilities to their advantage. However, with his incredible strength and adaptive nature, SpongeBob would be a very tough opponent for Tommy to defeat. Overall, the match would be very close and could potentially go either way. However, SpongeBob's Saiyan Physiology, along with his incredible power and adaptive capabilities, would give him a slight edge over Tommy Oliver/Green Ranger.

If SpongeBob were to fuse with both Goku and Vegeta, the resulting warrior would be extremely powerful and nearly unbeatable. The fusion of the three would create a being with the combined strength, speed, and abilities of the three characters, as well as all of their forms and evolutions. The character that would emerge from the fusion would be a Super Saiyan God with nearly unlimited power. They would have access to the full range of Saiyan forms and evolutions, giving them immense strength, speed, and durability. Additionally, their ability to utilize Goku's Kaioken technique along with Vegeta's Galick Gun and Final Flash would make them even more formidable. The fused warrior would also possess the strategic prowess of each character, making them almost unbeatable. With Goku's fighting experience and Vegeta's tactical mind, they could outmaneuver almost anyone they face in battle. Overall, the fused warrior would be virtually unstoppable, capable of overwhelming any opponent with their immense power. They could potentially wipe out entire armies or destroy planets with ease, leaving anyone who dared to oppose them completely helpless.

If SpongeBob were to fuse with both Goku and Vegeta in a battle with Tommy Oliver/Green Ranger, the result would be extremely one-sided. The fused warrior would be incredibly powerful and nearly unbeatable, possessing the strength, speed, and abilities of all three characters. With their combined strength and speed, the fused warrior could potentially defeat Tommy with just one blow. Their range of Saiyan forms and evolutions, along with the strategic prowess of Goku and Vegeta, would make it almost impossible for Tommy to gain any advantage in battle. Tommy may be a skilled fighter and powerful ranger, but he would be completely outmatched by the fused warrior. The Dragon Shield that Tommy wears for protection would be no match for the immense power of the fused warrior. Overall, the battle between the fused warrior and Tommy would be completely one-sided. The fused warrior would be virtually unstoppable, capable of overwhelming any opponent with their immense power and range of abilities. Tommy would stand no chance against the combined strength of Goku, Vegeta, and SpongeBob, and would likely be defeated quickly in battle.
