I understand your thoughs and i'll say my thoughs.
I won't deny, i'm dissapointed let me explain:
- Character wise: He exceeded expectations. Oda did a good job showing the guy who had a "I don't give a fuck about anything" vibe also had feelings and friends.
- Power wise: that's the problem. Kizaru is one of the most hyped characters in OP since 2010. Pika Pika No No is one of the coolest and strongest fruits of the series. The OP fandom has always waited to see the true extent of Kizaru's potential.
And then in Egghead:
- Kizaru fights with Luffy, a horrible fight in my opinion
- Kizaru doesn't fight seriously, the same Laser beams/Light sword attacks and didn't show anything new, besides the clones.
- Self-nerfed the entire arc
Self-nerfed Kizaru makes sense for character development, but hurts Kiz's potential.
The arc isn't over yet but if Kizaru doesn't show his full potential, it will be disappointing.
