No doubt a reference to the Giant Gymir, in Norse Mythology. 
- ω ϖ (30 energy) 10 yd range—Gymer smashes his fist into the ground, causing 5363 to 7637 damage to all enemies in a 12 yard radius.
- ω ϖ (50 energy)—Gymer lets lose a deafening roar, knocking back all enemies in front of him. (5 sec cooldown)
- ω ϖ 30 yd range—Gymer will grab a Vargul that he can then use as a living weapon! Also used to grab Storm Clouds so that Gymer can replenish his health and energy. (10 sec cooldown)
- ω ϖ (Unlimited range)—Throws the Vargul that Gymer is holding in his hand. Will explode on impact!
- ω ϖ 8 yd range—Crushes all reanimated corpes and ghouls in front of Gymer. Gymer CRUSH! (5 sec cooldown)
Randomly spoken quotes when caged:
- Wretched beasts!
- I will devour you whole!
- Ugly little monsters, pray I don't get out!
- Your torture only adds to my rage!
- My brothers will come for me and then you will see what true power is!
- How long do you think this cage can hold me, fiends?!
- I will crush you all!
While being ridden:
- Taste Gymer's size 600!
- Tiny creatures, I trample you!
- I will crush you under foot!
- I'll wipe you off my boots later!
- AAARRRRRRGGGGGGHHHHHHH!! SUCH POWER!
- LIGHTNING GUIDE MY FURY!
When he yells "Taste Grymer's size 600!", he is referring to his shoe size. It seems like giants have REALLY big shoes.
