There have been several iterations of Marvel's God of Thunder, Thor. Whether it be through the multiverse of a type of enchantment, fans have been treated with many alternate versions of the character. While some takes on the character were a hit with fans, others have been met with a lukewarm reception.

The character of Thor has cemented its place among many other iconic characters in Marvel's lineup. Ever since his introduction into the popular Marvel Cinematic Universe, his star has only risen even higher. His origin story and the core traits of the character have now become common knowledge. But some fans might not realize that there's been a whole stable of Thors that have graced the pages of Marvel's comics. Some were worthy, others were not.

10 Best: Old King Thor

Thor was always meant to take the mantle of King of Asgard. But his adventures on Midgard alongside Earth's Mightiest Heroes always prevented that. In the first issue of Marvel's series, Thor: God of Thunder, fans were finally able to see Thor sitting on the throne as King Thor.

This future version of Thor was far more weathered than the original Thor fans became accustomed to. After Asgard had been decimated by Gorr the God Butcher, the one-armed and one-eyed King Thor became the sole Asgardian left. Now sporting an eye patch as his father Odin once did, King Thor vowed to destroy Gorr the God Butcher once and for all with the help of his younger self.

9 Worst: Ragnarok (Clone Thor)

Marvel's Civil War had its fair share of misses. Among them was including a clone of Thor as opposed to the real one. This version of Thor, who would later call himself Ragnarok, was a cyborg-clone creation by none other than Tony Stark himself. Stark created the fake Thor with a strand of the real Thor's hair and fused the Asgardian DNA with his own Stark Technology.

If it wasn't bad enough that Iron Man cloned his longtime ally, he allowed for his creation to get out of hand when Ragnarok killed the hero Goliath by blasting him through the chest. This psychotic version of the God of Thunder was a low point in the history of Thor.

8 Best: Ultimate Thor

The Ultimate Marvel Universe line brought the original Marvel superheroes into the 21st century with brand new origin stories. One of those characters was Ultimate Thor. Whereas the mainstream continuity of Thor presented by Earth 616 was the banished Prince of Asgard, Ultimate Marvel's Thor was the God of Thunder reincarnated as a mortal anarchist by the name of Thorlief Golmen.

This version of Thor sported a sleek new costume and an impressive new axe-hammer. Ultimate Thor relied much less on Asgardian powers and didn't have the benefit of being able to use Mjolnir in battle. One of Ultimate Thor's most appealing traits however was the fact that no one actually believed he was Thor. His fellow Avengers, or Ultimates as they were known in the Ultimate Universe, shrugged Thor off as a lunatic who claimed to be the reincarnation of Thor.

7 Worst: Thunderstrike

The early '90s saw several new, younger heroes take on the mantles of iconic characters. One of those characters was Eric Masterson, who became Thor for a brief period. In fact, it was actually Eric Masterson who faced off against Thanos during the Infinity Gauntlet as opposed to the original Thor Odinson.

This particular version of Thor was just a bad product of his time. Marvel tried to turn Masterson into a viable hero when they renamed him Thunderstrike, but he just didn't work. The character's run ended after only 24 issues.

6 Best: Rune King Thor

Thor as Rune King Thor in Marvel Comics

Thor was always known as the God of Thunder. But his status as a deity was always a little exaggerated. There was no debate about Rune King Thor's status as a God, however. This version of Thor was able to tap into the Odin Force and gain omnipotence.

Rune King Thor was easily one of the most powerful beings in the universe. Second only to cosmic entities such as Eternity and The Beyonder, this particular Thor was well beyond the 616 version of Thor. His power was actually beyond any of his Avengers teammates.

5 Worst: Throg

Throg the Frog of Thunder in Marvel Comics

Thor turning into a frog has always been an iconic gag perpetrated by his mischievous brother, Loki. But Thor wasn't the only frog who was able to possess his immense power. Loki turned Thor into a frog at the end of Thor #363. The God of Thunder would then meet a frog by the name of Puddlegulp.

Puddlegulp, who was in fact a former human turned frog, aided Frog Thor in a war against rats waged by New York City's frogs. After Puddlegulp and Thor's battle against the rats, Thor actually left behind a sliver of his weapon, Mjolnir which led to Puddlegulp receiving Thor's powers. It was then that the frog became Throg, Thor's silliest incarnation.

4 Best: Jane Foster Thor

Jane Foster Thor

Jane Foster was the longtime love interest of Thor. It wasn't until her appearance in Thor in 2011 that her character finally gained prominence. Three years later, the character returned to the comics in a big way when she was revealed to be the newest iteration of Thor.

After Thor was deemed unworthy to lift Mjolnir, it was a cancer-stricken Jane Foster who was deemed worthy to lift the hammer and wield the power of Thor. Foster proved to be a formidable Thor. She wielded Mjolnir like no other, being able to control it's speed and trajectory in way's that the Odinson had never done before. This version of Thor was a welcomed change to the character that proved to be popular enough to include in the MCU.

3 Worst: Thorangutan

Marvel just couldn't help itself when it came to a good name pun. Throg had already proven to be a worthy animal capable of being a hero, but there was another animal hero who was able to carry the mantle of Thor. The animal in this instance was Thorangutan.

Thorangutan hailed from an alternative universe designated Earth-8101. In this reality, The Avengers was made up of superpowered apes rather than humans. Naturally, Thor became Thorangutan. The silliness of the character was enough for a chuckle but he was simply not as memorable as many of the other alternate versions of Thor.

2 Best: Beta Ray Bill

Among the many alternate versions of Thor, Beta Ray Bill stood out the most. Despite his silly name, Beta Ray Bill proved to be a hero worthy of Thor's power. He was the first being who was able to lift Thor's hammer, well before Jane Foster.

The mighty Korbanite struck out on his own and became a popular character in his own right. Armed with the powerful war hammer, Storm Breaker, Beta Ray Bill set out on his own adventures and became much more than just a Thor knockoff.

1 Worst: The Incredible Hulk Returns

Chris Hemsworth will always be known as Thor. However, he wasn't the first Thor to appear onscreen. Thor's first onscreen appearance was in the 1988 tv-film, The Incredible Hulk Returns. The film acted as both a sequel to the original 1978 series and as a backdoor pilot for a Thor television series.

Unfortunately, this Thor bore very little resemblance to his comic book counterpart. In addition to his cheesy Viking costume, this version of Thor acted as an unwilling servant to Donald Blake. The Incredible Hulk Returns couldn't have possibly done Thor any favor with its limited budget. Instead, it gave fans the worst version of Thor imaginable.
