Xenoverse Trunk's first appearance in a video game consisting of him trying to help guys completely beyond his league and only managing to slow down how fast they fly to Wheelo's base is pretty funny.
Even if XV Trunks doesn't directly scale to the feat could it still upgrade some higher Xenoverse characters? The Immeasurable Speed feat goes to the base saiyans and even if he doesn't help, Trunks is present to witness Nuova Shenron and the Super Saiyan 4s fight. Should that upscale Final Form Mira above those JM GT characters as Trunks finds his power
impossible? I don't remember if he has similar statements for earlier characters.
I also definitely think this crossover is before XV1 chronologically as Trunks is using an older time machine model compared to
what they use in the XV series.
