If a character existed in this era...

Force prodigies exist in all eras of Star Wars to combat the challenges of the day, and some eras had greater difficulties than others. But what if characters could time warp and return to a bygone time, would Hero of Tython have been an exemplary force user in the PT era, would Jains Solo have been capable of tinting Darth Krayt? What skill set or powers would make them stand out in their time period they've been chosen to go to, and would the force user be able to adapt? What characters Jedi or Sith would've proven themselves if sent to volatile war periods like the Vong war or TOR? And if he character is Sith where would they rank if competing with other notables in eras like the PT or Legacy?

The most probable example is Revan coming back, before that biozare made Revan reborn/come back to life every motherfacking, lucqs art was making a lot of well hidden easter eggs showing us that the Dark Lord of the sith ( DL of the sith and no sisi pussy Jedi Revan) might just be sleeping somewhere

Revan at Krayt era would have in a single speech taken all the sith by his side....
Revan is pretty good at manipulating peoples... He is really wise and clever on that matter...
Some comic book character that are declared intelligent just are mother****ing sorcerers or technicalls genius... that can make amazing device.. Revan is intelligent because he can put some galactic scale scheme with just nothing but himself (AKA Tzeench AKA Just as planned master) He is slightly above Eldrad level... If you have watch the mandalorian war and Jedi civil war you will have noticed that Revan is more than amazing at turning people on his side, and they say it at the begining of KotOR : there is no greater weapon than using the ennemy own weapons aginst him. Revan is like Griffith in Berzerk, he is gifted to look awsome and be an amazing leader, while in the inside he is a totaly selfish dick cappble of anythig to achieve his goal....

For the vong War, Revan would replace thrawn (cuz tactical genius) and will be really piss-off by the new republic destroying the galaxy gun and all that, he will have bad memeories coming back, remembering how the Jedi coucil was just lawful stupid during the mandolrian war, he will go berzerk slain the new republic leaders, declare himself emperor and order 66 Luke Skywalker Jedi order... While luke will go hide on Dagobah, Revan will kick Vong ass by using mandalorians and trained units (Vong always get ass kicked by a bunch of mandalorians mercs who are so broken since Malachor V than they dod not even form am army proof that the new republic forces were just a bunch of incompetent) revan will get really piss-off if they sacrifice an SSD (AKA the ultrasmurf did sacrifice an emperor class battleship to stop the nids..... And 40 000 fan think that was a terrible waste)

Actually there is an actual EaW mod where Canderous launch the vong invasion during the Jedi Civil war era... They just get eaten by nihilus in the end after that Revan find a way to lure the vong into being force sensitive cuz being force sensitive is awsome or almost awsome when nihilus is hungry....

Too broad. There are a great many possibilities depending on the character and the time period the aforementioned character was sent to. I think a good many of us could agree that Sidious being sent to the SWTOR period would be the most interesting.

Exar Kun vs ROTS Sidious duel it out for the mantle of Dark Lord would've been awesome to see.

I agree it would be awesome to see Exar die a horrible death
