DB | Raiden vs. Thor by Green-73 on DeviantArt (original) (raw)
Raiden defeated Shinnok in their first battle, who is powerful enough to merge all the realms, and that same battle almost destroyed the planet. He's also comparable to Fujin, who's attacks were capable of harming Cetrion, who can grow to the size of the planet.
Raiden claimed to be as fast as lightning. He defeated Shinnok in their first battle, who is comparable to Cetrion, whose attacks can reach a percentage of light speed.
Thor's clash with Jormungandr at Ragnarok shook and splintered Yggdrasil (the World Tree that holds entire planes of existence/dimensions with their own time flow/axis, and created the Realm Between Realms that surrounds and transcends them) and send the serpent back in time. He was also able to simultaneously hold back both Jormungandr and Surtr/Ragnarok, the latter being powerful enough to destroy Asgard along with it's branch in Yggdrasil (the same infinite branches that hold the realms and transcend all of time and space) and shaking it to it's very roots.
Thor could keep up with Kratos, who is superior to Primordials, whose punches created universe spanning shockwaves; and fought opponents like Persephone and Hercules who can block Helios' light, which is capable of illuminating all of the Underworld (which has statements of being infinite/limitless/boundless/immeasurable in size). Kratos also fought the Sisters of Fate, who are capable of projecting themselves at infinite speeds.
Thor is much more powerful and faster than Raiden.
