Teach and Cell has mindblowing similarities once you think about it. I think Oda was impressed by Toriyama's writing and wanted to quote some of it.
- Teach and Cell are central antagonists of their own manga who grew stronger as the manga went on.
- Cell was born with Frieza, Goku, Piccolo etc... genes pre-installed in his body. Went on to absorb 600k humans and two androids to peak.
- Teach was born with the ability to hold more devil fruit powers. Went on to absorb two devil fruits and soon a third.
- Both Teach and Cell have sworn enemies in Shanks and Trunks, who are coincidentally, sons of royalty swordsmen that warned others of a looming threat (Teach/Cell).
- Note that Shanks and Trunks share a hairstyle. Funnily enough Trunks' mentor lost his left arm protecting him too.
- Both Teach and Cell hijacked live broadcast to announce that they would destroy the world
- Both Teach and Cell are unable to sleep. Cell stood 10 days waiting for his tournament. Teach has insomnia.
- Both Teach and Cell were planning their rise to power since they were young
- Cell was planning to become complete all the way since he was a larval because Dr. Gero programmed the blue print info inside him. Cell knew what to do since he was in his healing pod
- Teach too was planning his rise to power since he joined WB as a teenager. He read the DF encyclopedia and realized that getting the strongest Logia, Paramecia and Zoan is essential to reach his potential
The concept of Davy Back, which Teach might do vs Luffy, could even mirror the Cell Games.
*Not that important but interesting: Cell made his debut in the Japanese release date of the DBZ chapter in August 3rd 1992. August 3rd being Teach's birthday.
