Didn’t Sanji almost break Blueno Tekkai and Franky almost break his face ?
And Kaku was part of carpenters and was the one working on the Merry
Yes, but Blueno was only DF User alongside Lucci, Kaku & Kalifa didn't have any at the time,
Blueno was the one who fought Luffy while Zoro fought Kaku, before Lucci sent both flying,
He was also the one standing in the middle if that counts showcasing Rokushiki Techniques, while Kaku & Kalifa had to share Rankyaku Showcase, (Misleading Readers that Kalifa can Kick as hard as Kaku)
He got grabbed by Franky but He wasn't allowed to use Shigan on him by Lucci, and Sanji almost break his Tekkai, but remember that when Kalifa captured the Train, She asked Blueno to hold it, making Readers think He is Toughest among them, and then after They managed to escape, it was Blueno who appeared behind Sanji in a very intimidating & memorable Scene, and ended up capturing the Prisoners again,
Blueno was the one who looked like Lucci's Right Hand Man (Not to mention He was older than Kaku & Kalifa, and looked more Dangerous), but eventually it turned out that it's cuz He was reserved for Luffy & Gear 2 Hype, not because He was anything close to CP-9's Top 3.
Killingham is also doing his own thing, but just because Sommers is given this Treatment doesn't mean He is Stronger or among Strongest, imo it means instead that He might be the first to say Goodbye or He is going to be Luffy's Victim or be the first one with Immortality that finally gets Hit, so Oda needs to Hype him asap
Bullies like him always get a very brutal Defeat, We've seen it countless times.
If a Commander is attacking Innocents or Side Characters, then They are getting almost R-Rated "Destroyed"
