Okay, as I was thinking about it, I know that SMG4 confirmed that SMG4 Tari and Meta Runner Tari are both different people from different universes despite similar personalities and powers, but I just had this thought while I was daydreaming.
I can imagine that at the end of the upcoming Meta Runner series (when it’s released and it reaches the end), Lux is stopping at nothing to capture Tari, in which Tari’s allies build a portal for Tari to send her to another universe to avoid being captured by Lux, and thus leaving her home universe and her friends, gets transported to the SMG4 Universe and gaining her SMG4 model. Remember SMG4: Mario The Ultimate Gamer, when Mario first met Tari? That could be where Tari might end up.
I know this is all 100% false, due to SMG4’s obvious confirmation that the two versions of Tari are different people, but this scenario was a “what if SMG4 didn’t confirm this?”. Thank you for reading this and have a good day.
