#2 Yoshi-HASHI

Yoshi-HASHI has unfortunately been absent due to an unfortunate spill during Gedo's betrayal against Okada. It seemingly feels like he got set as a featured element of the ongoing conflict and maybe even the World Tag League with the Rainmaker, with his and Jay White's Wrestle Kingdom match announced a bit later than it was currently.
Either way, Yoshi-HASHI has always been under the shadow of Okada. There's been a running joke among the wrestling fandom that he is nothing but an uglier version of the Rainmaker, undermining his positioning in the company and CHAOS. This could have been the spur to drive another wedge into Okada's back.
It would work perfectly in conjunction with the kind of character Jay White is, a perplexing satire of WWE's conventions. White having his hand in Gedo's betrayal of the Rainmaker is a pure sports entertainment element mixed with New Japan's penchant to drive out the old guard for the new in its factions. White elevating this trope to the best friend in the shadow of his glorious superior betraying him would be perfection. Unfortunately, Hashi's injury means we'll never know his true function in this ongoing feud.
