Kiva’s actually a lot stronger than I had remembered. His raw attack power is very impressive and his high levels of speed allow him to fight several enemies at once. Wii Fit Trainer excels at fighting from a distance, but I don’t see her being able to keep up with Kiva from long range either thanks to his strong energy blasts. His hammer grants him additional power and not even the Wii Fit Trainer’s energy bodies attack can keep him at bay. Kiva wins.

yes! yes! another win for my favorite rider!
Kiva’s rising up the ranks!
i’d consider kamen rider kiva to be one of the most powerful neo-heisei era kamen riders.
He definitely does seem like one of the strongest and his abilities are really cool to look at. He mixes fire and dark, which are two epic attributes.
characters like decade are really over powered, but i think Kiva might be able to defeat him. Decade does have all the powers of the past riders, but Kiva has his Mighty form. that’s why i think he’s so powerful.
