#2 Triple H

This might be hard for some to believe, but Triple H has appeared at every single WrestleMania since WrestleMania 12, with the sole exception being WrestleMania 23. He has been one of WWE’s biggest stars for almost twenty years and has been booked in high-profile matches almost every year at WrestleMania.
However, there is the possibility that WrestleMania 34 might be Triple H’s last WrestleMania. Not because of any injuries, but because he simply might not have time in the future. Aside from being an on-screen villain on RAW storylines, Triple H has numerous responsibilities outside of the ring as well. He’s the mastermind behind the NXT brand, and also has numerous other roles in WWE’s corporate environment as well.

Moreover, there are rumours that Triple H’s day-to-day responsibilities will increase in the coming years as Vince McMahon shifts his focus away from the daily grind of managing WWE.
As Vince begins to deal with old age and shift his attention to the XFL, Triple H is being groomed to take over many of the tasks that were/are on Vince’s shoulders. Because of this, there simply might not be any time in in the coming years for Triple H to wrestle and promote a storyline for future WrestleManias.
