Taek Jegal was one of the most powerful GOH characters early on but at this point he has definitely been surpassed by several characters. Daewi is one of them as the guy has really ended up becoming a true threat. His fists would be able to destroy Taek in a single blow to the point where the guy would not be able to regenerate. Daewi’s barriers would also be too formidable for Taek to break through with pure power. Ultimately this wouldn’t even be close. Daewi wins.
