Ke-Pa

Because Ke-Pa was the King of all Demons. So Baigujing should be his servant too.

Because Oogway seems to fight at the same time against Ke-Pa than the four Four Constellations against Jindiao. That could be the reason why Oogway couldn't help the Four Constellations with Jindiao. And he defeated Ke-Pa with his Chi of hero like the Four Constellations.

Also, does Oogway's seal contain the demons or acts as a doorway from the underworld to the mortal realm ?

So I wanted to know what you guys think on this subject. Because we have several competitors that have never stood back-to-back before. Other than Ke-Pa, they're 4 or 5 contestants that I'd like to address and I'd also like you guys to tell me what heights you think these characters are. There's never truly (IMO) been a truly great KFP size comparison youtube video before. So here's what I think.

I think the tallest is either Kim the Invincible, Temutai, Constable Hu or Lidong. Possibly Lao Shu the Elephant in POD, Kai from KFP3 and not counting mystical or demonic beings such as dragons like Jindiao or the White Bone Demon.

My Height Guesses:

Temutai: 12 ft

Kim The Invincible: 10ft

Constable Hu - 11 ft

Lidong: 12 ft standing (20- 40 ft with tail and snout elongated)

Kai - 8-9 ft (12 ft with additional horns)

I don't know about Superintendent Chang because he never actually stood up but being a Horse I believe he is a close contender.

Ke-Pa is a demonic Galactic Chinese Dragon that teamed up with the Vilgaxian Alliance and aligned himself with Vilgax, Azmuth, Eon, Maltruant, Kira Kozu, Zurg Supreme III and The Evil Helmet. He is currently lurking in the shadows as he, Kira Kozu and Maltruant have kidnapped Dagon from his dimension and are slowly draining his powers to unleash ultimate destruction.
