1. Ryokugyu Appears ---> Momo shows Kaidou's Signature Attack
2. Aokiji Appears ---> Koby shows Garp's Signature Attack
3. Kizaru Appears ---> Bonney shows Luffy's Signature Attack
Weevil is another Kid with Crazy Potential just like Momo, Koby & Bonney
And He will Copy WB's Signature Attack Obviously (His DF-Less One, like Thunder Bagua)
We should learn what happened to him when the Story starts focusing on Fujitora or Akainu again
