My Hero Academia Union Arena (UE25BT): Release Date, Box Price & Is It Worth Opening?
Published October 22, 2026 · Prices updated October 22, 2026
My Hero Academia releases on December 11, 2026 (50 days from now). Presale boxes cost $299.69 on TCGplayer, 123% more than Union Arena's latest debut sets sell for today ($134.66 on average). For Union Arena's latest debut sets, the typical box opened was worth less than the box itself in 6 of 6: the value sits in star parallels most boxes never hit. Buy boxes to open for fun or to keep sealed, and buy singles for specific cards. We'll publish My Hero Academia's real numbers a few days after release.
This is a Special Booster, which may not follow the regular booster box layout. We'll update the pull estimates once English boxes are opened.

Should you preorder?
Preorder prices are set by shops guessing demand, and Union Arena boxes have moved both ways after release: some sell for well above their launch price a year later, others for less. If you want specific My Hero Academia cards, waiting for singles is almost always cheaper. If you're buying to hold sealed, you're betting the set ends up above its presale price, which nobody can know before the chase cards are revealed. A free price alert on the My Hero Academia box emails you if the presale price drops.
