>Cody, having won the Royal Rumble is looking for revenge against Roman Reigns, and is hoping to make some alliances that will prevent Bloodline interference
>Seth is looking to legitimize his title run, after being buried by the 'main' world champion. He originally wanted Cody to choose him to fight at Mania, as he has an 0-3 record against him, and he feels like beating Cody would legitimize him as the top guy. Despite being disappointed in Cody's decision to pursue Roman, he's allied himself with Cody. There's tension as to whether or not he will betray him at Mania
>Drew Mcintyre is bitter about having had his 'Wrestlemania moment' in 2020, in front of an audience of no one. He's tried to regain the championship the 'right way' several times, but keeps getting either unlucky or is actively screwed over, so now he's fully embracing dirty tactics to finally earn a championship in front of an audience.
>Bayley founded a faction with Dakota Kai and Iyo Sky, but has been the least successful member of the faction. Dakota Kai and Iyo Sky have been tag team champs multiple times, Iyo is now world champ, and as Dakota is currently injured, Iyo brought Asuka and Kairi Sane into the faction, who are now tag team champs. Iyo was planning to push Bayley out of the faction, but Bayley won the Royal Rumble and is now going to challenge Iyo for her title.
>Rhea Ripley is one of the most dominant champions in the history of Women's Wrestling. Becky Lynch is determined to prove that she's still 'the man', and can beat a dominant champion like Rhea.
Just off the top of my head.
